Rock's

1. Earth's crust began as Molton Rock. 

2. In the beginning, all rocks were Igneous.

3. Volcanoes deliver igneous rocks to the surface.

4. Rock that forms underground is called intrusive. 

5. Rock that forms from from igneous rock fragments (sediments) are called sandstone. 

6. Sand that is formed into rock is called living things.

7. Layers of coal are formed from sandstorm.

8. Limestone is formed from volcanic rock

9. Rocks that have been changed since they first formed are called metamorphic

10. Limestone under great pressure turns to high formed rock.

11. When metamorphic rock reaches the surface, it weathers and becomes Lava

The Thermal Structure and Chemical Composition of the Earth's Atmosphere

1. The Layers of the gases that make up the earth's atmosphere are nitrogen which the % is 78, oxygen 21%, argon 0.9%, carbon dioxide 0.03%.

2. The atmosphere is within 300 miles thick, but most of it is within 10 miles of the  surface os the earth. 

3. The air pressure within the earths surface is 10 pounds per square inch. 

4. Troposphere thickness is the lowest region in the earth and the altitude increases.  

5. Stratosphere is 11 and 31 miles above the earth's surface and it reaches lower. 

6. As the altitude decreases then stratosphere increases. 

7. The earth was formed by planetary degassing. 

8. Since the earths formation life has modified the earth. 

9. The atmosphere is mostly made out of different gases.

10. nitrogen is important to life processes.

11. Oxygen is the second most gas in our atmosphere.

12. Oxygen is good for time to time and place to place. 

13.  Carbon dioxide  is the third most gas in our atmosphere and its good to keep the earth warm. 

14. The gas that is forth in the atmosphere is argon. 

15. The other non- gases that are in the atmosphere are water vapor, dust particles, and ozone. 

Planet's Atmosphere

2. The original atmosphere was similar to what planet's atmosphere?The original atmosphere may have been similar to the composition of the solar nebula

4. What happens in the Troposphere? Answer the question and add an image that represents the answer. The troposphere is where all weather takes place; it is the region of rising and falling packets of air.

5. What happens in the Stratosphere? Answer the question and add an image of Stratospheric Clouds.

Above the troposphere is the stratosphere, where air flow is mostly horizontal.

6. What is the Ozone Layer primarily responsible for?The thin Ozone Layer in the upper stratosphere has a high concentration of ozone, a particularly reactive form of oxygen

7. Go here, find an image that has something to do with the Ozone layer and explain what the picture shows. The Ozone Layer is the one who surrounds the entire earth.

8. What takes place in the Ionosphere? Find a picture that represents it and post it. Answer the question also. Ionosphere is the one that is responsible for absorbing most energetic photons form the sun. 

Earth's Atmosphere

1. Earth's Atmosphere-The earth's is surrounded by a blanket of air,which we call the atmosphere 

2. Troposphere-The troposphere starts at the Earth's surface and extends 8 to 14.5 kilometers high (5 to 9 miles). This part of the atmosphere is the most dense. As you climb higher in this layer, the temperature drops from about 17 to -52 degrees Celsius. Almost all weather is in this region. The tropopause separates the troposphere from the next layer. The tropopause and the troposphere are known as the lower atmosphere.

3. Stratosphere- The stratosphere starts just above the troposphere and extends to 50 kilometers (31 miles) high. Compared to the troposphere, this part of the atmosphere is dry and less dense. The temperature in this region increases gradually to -3 degrees Celsius, due to the absorbtion of ultraviolet radiation. The ozone layer, which absorbs and scatters the solar ultraviolet radiation, is in this layer. Ninety-nine percent of "air" is located in the troposphere and stratosphere. The stratopause separates the stratosphere from the next layer.

4. Mesosphere-The mesosphere starts just above the stratosphere and extends to 85 kilometers (53 miles) high. In this region, the temperatures again fall as low as -93 degrees Celsius as you increase in altitude. The chemicals are in an excited state, as they absorb energy from the Sun. The mesopause separates the mesophere from the thermosphere. The regions of the stratosphere and the mesosphere, along with the stratopause and mesopause, are called the middle atmosphere by scientists. This area has been closely studied on the ATLAS Spacelab mission series.

5. Thermosphere-The thermosphere starts just above the mesosphere and extends to 600 kilometers (372 miles) high. The temperatures go up as you increase in altitude due to the Sun's energy. Temperatures in this region can go as high as 1,727 degrees Celsius. Chemical reactions occur much faster here than on the surface of the Earth. This layer is known as the upper atmosphere. The upper and lower layers of the thermosphere will be studied more closely during the Tethered Satellite Mission (TSS-1R).
