Atmosphere Review

Some text here about the topic of discussion

​There are 5 Main layers of the atmosphere:

1. ​Troposphere

2. Stratosphere

3. Mesosphere

4. Thermosphere

5. Exosphere​

​Some text here about the topic of discussion.

​How do we tell where they begin and end?

​The layers are separated by temperature.

Multiple Choice

What happens to temperature as you go from Troposphere to Stratosphere?

• Temperatures increase as you go up

• Temperatures decrease as you go up

Multiple Choice

What happens to temperature as you go from Mesosphere to Thermosphere?

• Temperatures increase as you go up

• Temperatures decrease as you go up

Multiple Choice

What is one way the troposphere and the mesosphere are alike?

• Weather occurs in both

• The thickness of the layers is the same

• Both layers have a layer of ozone near the top

• It gets colder as you go up

​The amount of air pushing down on an object.

Imagine a column of air on top of your head​

​Air pressure

​Mass divided by volume

​

The amount of mass in a given volume​

​Density

​The distance above Sea level

​

Sea level is 0 ft. ​

​Altitude

​Remember:

The higher you go up in altitude, the lower the air pressure. ​

​for example:

The air pressure in the mesosphere is lower than in the troposphere because it is higher up. ​

Multiple Choice

Which layer has the highest air pressure?

• Troposphere

• Stratosphere

• Mesosphere

• Thermosphere

• Exosphere

Multiple Choice

Which layer has the lowest air pressure?

• Stratosphere

• Mesosphere

​Greenhouse effect:

​Greenhouse gases trap heat in the atmosphere.

​

Carbon dioxide is the most abundant greenhouse gas. ​

​Why is it important?

• ​Volcanic Eruptions

• Animals breathing

• ​Decaying plants

  ​

​Natural Effect

​Burning Fossil Fuels

• Driving cars

• Flying Planes

​Human Effect

​It keeps temperatures on earth steady

Multiple Choice

What is the importance of Earth's natural greenhouse effect?

• It provides water for plants to grow

• It keeps temperatures on earth steady

• It produces gases that make up air

• It causes seasons to happen every year
