TOPIC 2

Question 1

varies as one moves upward from the surface of the Earth

Answer 1

Temperature of the Earth

Question 2

Region where nearly all water vapor exists and essentially all weather occurs.

Answer 2

troposphere

Question 3

the temperature decreases with height at the rate of approximately 6.5°C per 1000m of altitude.

Answer 3

tropophosphere

Question 4

increases with height, and regions where the temperature decreases with height.

Answer 4

Temperature

Question 5

Temperature decreases with altitude since it absorb very little of the incoming solar radiation.

Answer 5

troposphere

Question 6

Heating is most effective near the ground

Answer 6

troposphere

Question 7

Region above the troposphere and a region where temperatures actually increase with increasing height.

Answer 7

stratosphere

Question 8

Temperature remains isothermal until about 20 km.

Answer 8

stratosphere

Question 9

directly warmed by the Sun

Answer 9

stratosphere

Question 10

higher concentration of ozone

Answer 10

stratosphere

Question 11

an effective absorber of solar ultraviolet radiation.

Answer 11

stratosphere

Question 12

Approximately 90% of the ozone in the atmosphere resides in the?

Answer 12

stratosphere

Question 13

Ozone concentration in the this region is about 10 parts per million by volume (ppmv) as compared to approximately 0.04 ppmv in the troposphere.

Answer 13

stratophere

Question 14

Air is very thin at this height and temperature decreases with increasing height.

Answer 14

mesosphere

Question 15

The thin air and small amounts of ozone prevent the air from warming much.

Answer 15

mesosphere

Question 16

The region of the atmosphere where the most energetic solar energy is absorbed.

Answer 16

thermosphere

Question 17

Region where ultraviolet radiation, visible light, and high-energy gamma radiation are all absorbed by the thermosphere, which causes the few particles present to heat up considerably.

Answer 17

thermosphere

Question 18

Amount of water in the air relative to the saturation amount the air can hold at a given temperature multiplied by 100.

Answer 18

relative humidity

Question 19

higher value of RH means that the atmosphere is?

Answer 19

nearing saturation

Question 20

a lower value means the atmosphere is?

Answer 20

far from saturation

Question 21

the molecules in the air apply pressure to everything on earth, including us.

Answer 21

air pressure

Question 22

High pressure in the atmosphere causes?

Answer 22

the air to compress and sink, leading to clear skies and calm conditions.

Question 23

Measures the ‘heaviness’ of an object or how closely ‘packed’ the substance is.

Answer 23

density

Question 24

Measure of number of air molecules in a given area.

Answer 24

density

Question 25

Higher the number of molecules the?

Answer 25

dense the air is
