D, Review and Reinforce – . factors as climate, natural resources, and economic How scientists use radioactive dating of rocks to determine major events in Earth's. The key to weather prediction lies in accurately measuring these variables and feeding the data into numerical models that can predict changes.
What I can offer is my own experience as it relates to the accuracy of the Bible.
The fatal flaw with radioactive dating methods
The truth found there transformed my life from one of confusion, selfishness, and uncertainty to one of peace, purpose and understanding. When I realized that Jesus died on a cross because of people like me or more specifically for me, I chose in that moment to surrender my life to Him. From that moment I was filled with peace in knowing that regardless of where the path would lead, as long as God was in control, it mattered very little which direction it took.
Only that if God was leading it would be right and good. Well, 24 years later I can say that has been true and so has the Bible.
Yes, believing in a young earth sometimes takes faith but not near as much faith as it takes to believe in evolution. I think one has to work hard to believe that the intelligent design behind even the simplest organism is due to random formations of the elements around us. Since I have a personal and intimate relationship with the One who gave me new life, and since His Word the Bible has proven itself true over and over in spiritual things, I feel the other facts found there pertaining to creation etc.
My prayer for them is that the God of all creation will have mercy on them and open their eyes to the glorious truth revealed in Jesus Chist, that they might find peace and eternal life with the One who is love. November 27, Glauron got me right. Their admissions of no eyewitnesses are enough to lead one to presume that these stories have been embellished.
The Torah is the Hebrew name for the five Books of Moses. If the texts were embellished then you would think that they would have whitewashed their heroes. December 31, Adam was there. He could have easily recorded the events after he was created. And we know from the biblical record that he personally talked with God. He is only six days out from the original creation. Light March 8, ALL recorded history goes back only a little over years which is also the age of man according to the Bible — there is no older written history.
Earthquakes in one place after another were all predicted and if you study the statistics for earthquakes you will find that they have increased exponentially starting with There are many more prophesies that are coming true NOW.
Read Matthew chapter 14 and Like chapter 21 to see the change in conditions predicted for the time we live in and 2 Timothy Chapter 3 for the predictions of the increasing bad attitudes of PEOPLE in this time.
If you found a very primitive little hut made of sticks constructed in the middle of what you thought was an uninhabited island you would conclude that some intelligent being had constructed it — you would NOT ever think that the sticks came together and were tied together with vines to form a roof and walls by coincidence from the wind!

And you that chose to believe this consider yourselves somehow superior in intelligence compared to those that believe in an intelligent creator? Can't Stop Believing March 16, When you throw in all of the recent scandals of climate-gate, one has to really question the integrity of the scientific community.
HG April 3, Radiocarbon Dating is used on organic objects only, so the fact that your whole example is based on inorganic rocks and radio carbon dating only suggests that you do not know with any detail or understanding the topic that you are discussing. Your arguments have no research, you have a biased opinion because of your faith, and are not willing to look at the truth, only your version of it.
The atmosphere is composed of a mixture of gases that exert pressure in all directions, pushing equally on all sides of our bodies. The higher you go in the atmosphere, the lower the air pressure, which makes sense as there is less air above you, pressing down. In the lower levels of the atmosphere close to the earth's surface, the weight of all the air above squeezes the air molecules together, making it denser and heavier.
By contrast, in the higher levels, there is less weight above to force the air to compress, and the air molecules can spread out more, making it lighter and less dense. Now place a piece of cardboard over the top of the cup and hold it in place while you quickly invert the cup. Take your hand away. If atmospheric pressure were not pushing up against the cardboard, the weight of the water would push the cardboard off, causing the water to spill out.
Because the air does push up, though, and with a greater force than the water exerts, the cardboard stays in place, appearing to "stick" to the cup.

For example, the air pressure is lower at the top of a mountain than it is at the base. This is the reason you were asked to set your barometer to the mean sea level pressure in Chapter 1. That allows you to compare your readings with those of other schools because all the barometers are using the same reference point - the elevation of zero. Air pressure decreases with altitude Note If your students are interested in making a barometer try Activity number 3.
Although you cannot see or hear air pressure, you do feel it, especially when it changes rapidly. For example, if you have ever flown in an aircraft, ridden in the elevator to the top of the CN Tower or taken a chairlift to the top of a ski mountain, there is a good chance your ears popped at some point during the journey. That pop signaled a rapid change in air pressure. Note To show your students that air exerts pressure try Activity number 4. The air pressure also changes when the air heats up or cools down.
When heat, a form of energy, is added to a parcel of air, the air molecules move faster and tend to move farther apart from each other. Consequently, when air warms up, it expands and becomes lighter.
Conversely, cold air is heavier and denser because the air molecules are less active and closer together. As the atmosphere strives to create a balance, the air moves from areas of high pressure, which are often associated with cool air, to areas of lower pressure, which are often areas of warmer air.
The greater the contrast or difference in air pressure between the two areas, the stronger the winds. Top of page Local Winds The global pattern of winds establishes the prevailing winds over large regions. In Canada, for instance, the prevailing winds are from the west. But local differences in air pressure and air temperature as well as lakes, hills and valleys also affect the direction and strength of the winds.
Note If your students are interested in making an anemometer and wind streamer, try Activity number 5 and Activity number 6. The atmosphere behaves like a liquid. If you scoop a cup of water out of a bucket of water, what remains quickly flows in to fill the hole and restore the balance.
So it is with air. The atmosphere tries to create a balance by flowing from areas of high pressure to areas of low pressure. Here, too, the Coriolis force affects the direction of the winds. They blow clockwise around and out of a high pressure area and counter-clockwise into a low pressure area. The greater the difference in air pressure between the two areas, the harder the winds blow. In Canada the wind speed is given in kilometres per hour and the direction is named for the direction from which it blows.
For example, a north wind comes from the north. Wind Circulation in the Northern Hemisphere: Winds blow counter-clockwise into an area of low pressure and clockwise around an area of high pressure. Fast Fact If you stand with your back to the wind in the Northern Hemisphere, the area of lower pressure will be on your left.
Check it out using the diagram of pressure centres and winds. If you stand with your back to the wind in the Northern Hemisphere, the area of lower pressure will be on your left. Local differences in temperature also help to create local winds, particularly around large lakes such as the Great Lakes. For instance, since land heats up more quickly than water, the difference in temperature between the two creates a breeze.
What happens is this. On a warm, sunny day the land near a lake heats the air above which then rises. Cooler air from the lake blows in to replace the rising air, which travels out over the water where it cools and sinks to replace the cooler air blowing on shore.
In this cycle, the winds blowing on shore are called Lake Breezes. In the evening when the sun has gone down, the cycle reverses itself. Since land also cools more quickly than water, the air over the water is now warmer than the air over the land. The air heated by the water rises and is replaced by cool air from the land. At the same time, the warm air from the water moves over the land where it cools and sinks. In this cycle, the winds blowing off shore are called Land Breezes. A similar process occurs between hills and valleys, where the valleys are normally cooler than the hills during the day.
Cities and natural features of the landscape such as forests also affect winds. Cooler air over water moving towards land; Air heating over land and rising; Warm air cooling and descending.
Warm air over water rising; Air cooling and descending; Cooler air over land moving towards water. In the glossary of Canadian winds a Barber does not cut your hair. A Barber is a strong wind which brings precipitation that freezes on contact, especially if the contact is with hair or beard.
A Flaw is not a mistake but another name for a Scud or sudden gust of wind. Top of page Air Masses The water and land heat or cool the air above them. This creates large masses of air with roughly the same temperature and moisture content. These air masses extend for hundreds of kilometres and are often classified according to the region that produced them.
For example, air which sits in the Arctic for a few months during the dark days of the polar winter turns cold and dry like the snow and ice below.
Meteorologists may call this an Arctic air mass. Similarly, air which sits above the Gulf of Mexico or the Caribbean Sea during the summer months becomes warm and moist.
This type of air mass is often called tropical. Air masses over North America in the summer. Air masses over North America in the winter. The weather would be easy to forecast if these air masses stayed put. But they do not. They move, pushed by the circulation of air in the upper reaches of the troposphere. As air masses move, their temperature and moisture content change.
For example, an air mass travelling down from the Arctic may warm up as it moves over southern Canada. If the air mass also passes over a large body of water such as Great Slave Lake or Lake Superior, then the air mass may pick up moisture too. Conversely, an air mass may also dry out as it moves inland from the Pacific Ocean. In this case, the air mass may lose its moisture in the form of rain or snow as it rises and crosses over the Coast and Rocky mountains.
There is one other point about air masses, which you have probably noticed. They do not always enter or leave quietly. Top of page Fronts A front is the boundary or transition zone between an air mass, which is entering a region, and the air mass, which is leaving it. Usually the two air masses have originated in quite different places, such as the Arctic and the Caribbean.
Consequently, they possess different characteristics of temperature and moisture. The interaction between the two air masses may produce dramatic changes in weather, and sometimes, violent weather itself, such as high winds and thunderstorms. Meteorologists name fronts after the air mass that is entering the region. If cold air is pushing in from the Arctic, displacing the warm air, then the leading edge of the Arctic air mass is called a cold front.
If cold air is retreating, allowing warm air to move in, then the leading edge of the warmer air mass is called a warm front.
A warm air mass will never push a cold air mass out of a region because cold air is heavier and denser. Interestingly, the slope of a cold front is, on average, 4 times steeper than the slope of a warm front. That is because when a cold air mass pushes into an area, there is friction, called surface friction, between the advancing air and the land. This friction causes the leading edge to buckle somewhat. Thunderstorms often develop more quickly along a cold front, because its steeper slope lifts the warm air ahead of it up rapidly, creating ideal conditions for the quick formation of thunderclouds or cumulonimbus clouds.
Cold Front, Warm Front: The slope of a cold front is steeper than that of a warm front because of the friction between the cold air and surface. To show your students why a cold front has a steep slope, ask them to rest their hands flat on their desks with their palms down. Then ask your students to slide their hands forward toward the front edge of the desk, pause, and pull them backward to the original position. What happened to your students' fingers as they pushed their hands forward?
Was there a difference when they pulled their hands back? The students' fingers probably buckled when they pushed their hands forward, as advancing air does, and then flattened when they were drawn back. This is similar to retreating air. Top of page Weather Maps One of the tools that forecasters use to identify and locate air masses, pressure systems, and fronts is the weather map. These maps are normally prepared at 3- or 6-hour intervals.
Weather observations from hundreds of places in North America are plotted on a weather map like the one on the next page.
As there isn't enough room to write out all the observed information and still have the map readable, a code was developed to condense the information into a smaller space. This code is called the station model. The station model uses a graphical format to fit all of the following information into a space about the size of a dime: Temperature and dew point Amount of the sky covered Visibility and present weather conditions Types of clouds present Change in pressure over the last 3 hours and whether it's rising or falling Here's how a simple station model looks.
