Week 17 Atmosphere

What is the atmosphere?

• all of the water

• all of the gases

• all of the organisms

• all of the soil and rocks

Water vapor is invisible. Liquid water can be seen. Clouds form when water vapor cools, then condenses into water droplets. The stratosphere is warmer than the troposphere. Why are there rarely clouds in the stratosphere?

• The stratosphere makes the clouds invisible.

• Water droplets evaporate in the stratosphere.

• The stratosphere is too far away to see clouds.

• No water droplets can reach the stratosphere.

How might the atmosphere affect the geosphere?

• An avalanche buries a pond.

• A river carries soil into the ocean.

• A tornado removes soil from fields.

• An earthquake knocks down buildings.

How might the atmosphere affect the biosphere?

• Waves carve caves in a cliff.

• Warm ocean water forms storms.

• Wind causes a wildfire to grow larger.

• A volcanic eruption creates new land.

What causes a convection current?

• Warm air falls, and cold air rises.

• Warm air rises, and cold air falls.

• Microbursts force air downward.

• The ozone blocks and absorbs heat.

What would happen to the biosphere if the ozone layer thinned?

• Plants would grow larger due to more sunlight.

• Cancer would increase due to ultraviolet radiation.

• Glaciers would melt due to increased temperatures.

• Sea animals would lose habitats due to smaller oceans.
