Apes 4.4, 9.1, 9.2

Question 1

Troposphere

Answer 1

Layer closest to earth. Temp decreases as you get farther away from surface of Earth. Where weather occurs.

Question 2

Stratosphere

Answer 2

Layer above Troposphere. Less dense & contains ozone layer which absorbs UV-B & C radiation

Question 3

Stratosphere temp

Answer 3

Increases as the altitude gets higher, because the upper stratosphere absorbs more radiation that converts to heat

Question 4

Next three layers after stratosphere

Answer 4

Mesosphere, thermosphere, exosphere

Question 5

Unequal heating (sun angle)

Answer 5

Sun strikes equator at perpendicular angle while strikes polar regions at more oblique angle - heat is much more spread out for polar regions

Question 6

Albedo

Answer 6

The percentage of incoming sunlight reflected by a surface

Question 7

What Earth’s axis of rotation leads to

Answer 7

tilted 23.5 degrees. Latitude receives most direct rays of sun & most hours of daylight changes throughout the year as Earth orbits the sun

Question 8

UV-B radiation

Answer 8

Harms plants’ ability to perform photosynthesis. Increases risk of skin cancer and cataracts for humans

Question 9

UV-C radiation

Answer 9

Causes tissue & DNA damage in organisms

Question 10

CFCs

Answer 10

Introduce chlorine, which binds to ozone & takes an oxygen atom, forming chlorine monoxide. Chlorine monoxide, then reacts w/ an oxygen atom, forming O2.

Question 11

Whats causing global trend of decrease in stratospheric ozone

Answer 11

Increased concentration of chlorine in the atmosphere
