1

What is the layer of gas that surrounds the earth?

Atmosphere

2

What are the layers of the atmosphere?

1. Troposphere
2. Stratosphere
3. Mesosphere
4. Thermosphere
5. Ionosphere

3

Which layer contains gases essential for life?

Troposphere

4

Which layer does weather occur in?

Troposphere

5

In what layers does the temp decrease as the altitude increases?

Troposphere and Mesosphere

6

In what layers does the temp increase as the altitude increases?

Stratosphere and Thermosphere

7

Which layer includes the ozone?

Stratosphere

8

Which layer do planes fly in?

Stratosphere

9

Which layer is 50-80 km?

Mesosphere

10

Which layer begins to merge with space?

Thermosphere

11

Which layer has air that is highly ionized by UV rays?

Ionosphere

12

What is special about the Ionosphere?

1. It keeps radio waves from completely leaving the atmosphere
2. It causes Auroras

13

What gases are found in the atmosphere?

Oxygen, Nitrogen, CO2 and Argon

14

Where are most of the gases found?

In the lower atmosphere

15

Which component of the atmosphere formed from the surface of the earth and pollution?

Dust

16

Which component is always present due to evaporation and is mostly near the surface?

Water vapor

17

Which component blocks UV rays in the higher atmosphere and is considered a pollutant in the lower atmosphere?

Ozone

18

What are ionized particles sent out by the sun?

Auroras

19

What are single oxygen molecules bounded with paired oxygen?

Ozone

20

What does the Ozone do?

It blocks 99% of UV radiation

21

What is causing ozone thinning?

The release of CFC's

22

Where is the hole in the ozone?

Antarctica

23

What does dust form in the atmosphere?

Rain and fog

24

What is the transformation of water vapor to liquid when it comes in contact with a cooler object?

Condensation

25

What is energy in the form of water?

Radiation

26

What is the direct transfer of heat from a hot object to a cooler object?

Conduction

27

What is the transfer of heat as warm air or liquid rises and cools air or liquid falls?

Convection

28

What is the only way heat can enter the earth?

Radiation

29

What is the effect that traps heat radiation that radiated from the earth?

Greenhouse Effect

30

Why is the greenhouse effect necessary for life?

The earth would be frozen without it

31

What is the main cause of the modern greenhouse effect?

CO2

32

What are some other causes of the modern greenhouse effect?

Burning fossil fuel, deforestation, methane, and CFC

33

What is the relationship between temperature and altitude?

As altitude increases, temperature decreases

34

What is an upside down temp, condition where the ground radiates heat and cools faster than air?

Temperature Inversion

35

How does temperature inversion form?

Cool air stays near the ground and traps smoke, fog, and other pollutants

36

What is smoke and fog mixed together?

Smog

37

How does the rotation and the tilt of the earth effect the temp of the earth?

1. The closer you are to the equator the more direct sunlight you are going to get, causing small differences between the warm seasons.
2. The middle part of the earth gets direct rays half of the year, causing extreme differences in the seasons

38

What is going on during the Winter Solstice?

The sun's rays are below the equator at the tropic of capricorn and are starting to go higher

39

What is going on during the Summer Solstice?

The sun's rays are above the equator at the tropic of cancer and are starting to go lower

40

What is going on during the Spring Equinox?

The sun's rays are at the equator and are rising

41

What is going on at the Autumnal Equinox?

The sun's rays are at the equator and are falling

42

What are the seasons of the earth like in the polar regions?

There are few direct rays, so it is cold most all of the year

43

What are the seasons of the earth like near the equator?

There is more direct sunlight, so there are only small differences between the warm seasons

44

What are the seasons of the earth like between the polar regions and equatorial regions?

There are direct rays for only half of the year, so there are extreme differences in the seasons

45

When are the warmest and coldest times of the day?

Warmest - Late afternoon
Coldest - Just before dawn

46

When is the warmest and coldest time of the year?

Warmest - July
Coldest - January

47

How is water heated and what affects the heating?

Heats up at different levels based on water clarity

48

How is land heated?

Only heats on surface, the top 1-2 feet

49

How does heat spread through water and land?

Much easier in water because of fluid and convection

50

What is it called when liquid water warms up and converts to water vapor?

Evaporation
