Exercise 10
Step 1
1 of 3
Albedo is the amount of radiation that something reflects.
Step 2
2 of 3
The albedo effect is that ice has a high albedo so it reflects a lot of radiation, lowering temperature, which allows for more ice to form. This is a positive feedback loop
Result
3 of 3
Albedo is the amount of radiation that something reflects.
Exercise 11
Step 1
1 of 4
a) far away from water would reduce the amount of moisture in the air thus the amount of precipitation would be lower
Step 2
2 of 4
b) prevailing winds make for a windy climate that may be slightly cooler as well as bring in rapid changes in precipitation
Step 3
3 of 4
c) mountains may protect areas from wind and lessen the amount of precipitation received by regions between mountains
Result
4 of 4
a) far away from water would reduce the amount of moisture in the air thus the amount of precipitation would be lower
Exercise 12
Result
1 of 1
The poles receive less sunlight that the equator does, so less energy is absorbed that helps heat the environment
Exercise 13
Result
1 of 1
Earth is always reflecting the sun’s energy just as it absorbs it
Exercise 14
Result
1 of 1
Greenhouse gases act as an envelope that lets in the sun’s energy, but prevents most of it from escaping. It warms the Earth like a blanket
Exercise 15
Result
1 of 1
The Earth’s atmosphere will absorb and radiate less energy since the sun transmits less energy, which would have an effect on the climate
Exercise 16
Step 1
1 of 3
a) As ice melts, its albedo lowers, which leads to more ice melting since it is a positive feedback loop.
Step 2
2 of 3
b) As ice albedo increases, less energy is absorbed and temperature decreases, causing more ice to form. This is positive feedback since the change results in an amplification of the change
Result

a) As ice melts, its albedo lowers, which leads to more ice melting since it is a positive feedback loop.
Exercise 17
Result
1 of 1
Color and size allow scientists to make predictions on yearly weather compared to normal years, and scarring could indicate forest fires.
Exercise 18
Result
1 of 1
The clouds of smog block sunlight and can lower temperatures or raise them depending on if the smog contains greenhouse gases
Exercise 19
Result
1 of 1
By blocking sunlight they can reduce temperature to prevent the accelerated vaporization of water. By the greenhouse gas effect they can increase temperatures, causing more water to vaporize
Exercise 20
Step 1
1 of 3
a) the winds off of the lake are often colder than the air in the city and bring precipitation due to the water evaporated off the lake.
Step 2
2 of 3
b) the Great Lakes create lake effect snow, which increases the amount of snowfall that downwind regions receive.
Result

a) the winds off of the lake are often colder than the air in the city and bring precipitation due to the water evaporated off the lake.
Exercise 21
Result
1 of 1
Earth’s climate system acts to regulate conditions on Earth. This involves the absorption and radiation of energy, the water cycle, and the carbon cycle. The regulation of these to the best of Earth’s ability allow for life.
Exercise 22
Step 1
