Unit 3 Study Guide Science

According to the image, which layer is the densest?

• The Troposphere is the densest according to the image.

• The stratosphere is the densest according to the image

• The mesosphere is the densest according to the image

• The thermosphere is the densest according to the image.

Using the Pie chart above what  is the

 majority of our atmosphere composed of? 

• According to the image, the majority of the atmosphere is composed of nitrogen.

• According to the image, the majority of the atmosphere is composed of oxygen.

How does temperature change throughout the layers?

• Troposphere: Decreases with altitude.

  Stratosphere: Increases with altitude.

  Mesosphere: Decreases with altitude.

  Thermosphere: Increases with altitude.

• Troposphere and Thermosphere increase, stratosphere and mesosphere decrease.

This is a lava lamp. When the light bulb heats the wax, the wax rises. When the wax cools, it falls. The cycle of rising /falling is an example of:   

• convection

• conduction

• radiation

At the beach the sand is scalding (very) hot! To cool off you run into the water because you know it is cooler. Explain why the water is cooler than the sand.

• The water is cooler than the sand because during the day, the water heats up slower than the land, therefore the water is cooler.

• The water is warmer than the sand because during the day, the water heats up faster
