Section 8-4: Components of Earth’s Climate System

Exercise 1

Step 1

1 of 3

a) atmosphere, hydrosphere, lithosphere, biosphere, and the cryosphere

Step 2

2 of 3

b) The atmosphere is the gases that surround Earth
The hydrosphere contains the waters of Earth
The biosphere contains the living organisms
The cryosphere contains ice
The lithosphere contains solid Earth such as rock and land formations

3 of 3

a) atmosphere, hydrosphere, lithosphere, biosphere, and the cryosphere

Exercise 2

Result

1 of 1

Troposphere, stratosphere, mesosphere, themosphere, exosphere

Exercise 3

1 of 1

This is not a contradiction because the ozone levels within the different layers can be dealt with separately.

Exercise 4

Solution 1

Solution 2

Result

1 of 1

The permanent ice creates cold regions where few plants and animals can live. These lands are often uninhabited by humans due to the poor weather

Step 1

1 of 2

Continual ice is an important part of the global climate system because it reflects light, so most of the sunlight that reaches the surface is reflected into the atmosphere, instead of heating the Earth’s surface. The presence and absence of ice affect the warming and cooling of the Earth’s surface and it also affects equilibrium energy distribution on the planet.

Exercise 5

Result

1 of 1

The large bodies of water have the capacity to store lots of thermal energy from the sun

Exercise 6

Step 1

1 of 4

a) The higher the altitude the lower the atmospheric pressure and often the colder the temperature and more likely to experience snow

Step 2

2 of 4

b) Mountain ranges often block winds but allow for snow and rain runoff

Step 3

3 of 4

c) The side of land that the wind goes to from the lake will be cooler since the wind carries cool air and rain from the lake

Result

4 of 4

a) The higher the altitude the lower the atmospheric pressure and often the colder the temperature and more likely to experience snow

Exercise 7

Step 1

1 of 3

a) If plants could absorb more carbon dioxide, the atmosphere would be cleaner and there would be more oxygen for us to breathe

Step 2

2 of 3

b) If organisms released more methane than the atmosphere would be in worse condition than it already is from cows and industry releasing methane

Result

3 of 3

a) If plants could absorb more carbon dioxide, the atmosphere would be cleaner and there would be more oxygen for us to breathe
