1. The Greenhouse Effect

The Greenhouse Effect is when the earth absorbs heat from the sun and surface warms up. then the earth cools off because it releases energy in the form of inferred radiation. The atmosphere is like a dome that keeps all the heat from escaping into space. This makes the atmosphere warmer and the earth too. If there was no Greenhouse Effect the Earth would freeze and so would all living things.

2. Heat Distribution in The Troposphere

Energy is distributed by radiation, conduction and convection. Radiation is the movement of energy in waves at or near the speed of light. Conduction is the movement of energy by direct contact. An example of this is a pan warming that is on the fire. Convection is the movement of heat by the mixing of a fluid. A fluid is a gas or liquid. Convection does not take place to a significant degree in solids since the molecules are not free to move like with gas or liquids.

3. The Wind

The wind can move easily from another place to place. Differences in air pressure cause the air to move. Wind is air in motion air moves from high pressure to low pressure the speed and direction of wind.

4. The Water Cycle

The water cycle describes the recent movement of water on, in or above the earth. Earth's water is always moving and is always going from state to state. The water cycle has been working for billions of years. All of earth's life depends on the water cycle.

5.Humidity in The Air

If Earth did not rotate wind would blow in a straight line from the North and South Poles toward the equator. This happens because earth is rotating a straight path the wind blows earth rotates from west to east.

6. How Clouds Form

Here are some steps on how clouds form.

  1. A warm layer builds up in the range of 1,000 to 5,000 ft.
  2. A warm layer builds up in the range of 1000 to 5000 ft.
  3. Arising air currents organize into thermals.
  4. water vapor in the rising air particles condense to form a cloud that is moist and soft

7. Rain, Hail, and Snow

Raindrops are formed from water condensing out of moist air that cools. Hail is formed when drops of water are pushed higher into storm clouds and freeze. They then fall and lay on the ground. Snow is formed when very cold weather freezes in the clouds. The crystals of snow form like rain around dust, but form light we know as snow instead of raindrops.

8. Three types of Storms

Thunderstorms are formed on a hot summer day. The surface of the Earth heats the air above the surface through the process of conduction. When warm air rises and cold air sinks (convection) plays a key role when forming a Thunderstorm. If the warm air is forced to rise it doesn't stop due to the less dense surrounding air. Lastly, it will transfer heat from the surface to higher levels of the atmosphere.

Winter storms receive their energy from two air masses of different temperatures and moisture levels. Winter storms usually form when an air mass of cold, dry, air moves and interacts with a warm, moist, air. The point where these two air types meet is called a front. If cold air arrives and pushes away the warm air, it forms a cold front. When warm air arrives, it rides up over the denser, cold air to form a warm front. If neither of these two air types arrives, it forms a stationary front.

An ice storm is a type of winter storm caused by freezing rain. Ice storms form when a layer of warm air is between two layers of cold air. Frozen precipitation melts while falling into the warm air layer, and then continues to freeze in the cold layer above the ground. This creates freezing rain or a glaze ice.

9. Changes in the Weather

Humidity tells you if there is enough moisture to create rain and clouds. Air movement affects the Earth because it is caused by tempature or pressure difference in the wind. Heat affects the weather when the air gets colder and hotter throughout the day.

10. Why you need to be able to predict the weather

Its important to be able to predict the weather, because you might have to plan a trip or if you have an outside job. You need to be able to predict the weather if you have a job like NASA, Airforce, Navy or if your a construction worker.
