Q

32
Q

What does the Gulf Stream bring to Northern Europe that has a huge impact on its climate?

A

Warm water/heat

33
Q

We had a recent day where the outside air temperature was -13°C (8°F). Does this mean that global warming is not occurring? Why?

A

No, it is an example of weather and not climate. Climate is the average weather over a long period of time

34
Q

What biome do caribou live in normally? What is an example of an adaptation that they have to survive in this environment?

A

Tundras, their spreading hooves are able to help them in the snow in winter and marshy tundra in summer. Hallow hair for insulation to help keep them warm.

35
Q

Name the 3 global convection cells that redistribute thermal energy from the equator to the poles.

A

Hadley cell,ferrel cell and polar cell

36
Q

Why is there typically more rain near the equator?

A

More direct sunlight leads to evaporation, the air rises, cools, condenses and then causes precipitation

37
Q

Why would two cities that have similar latitude and altitude have dramatically different climates? (An example would be Waterford, CT and Portland, OR).

A

Proximity to a large body of water and prevailing winds.

38
Q

Name the 3 major factors that influence climate.

A

Latitude,altitude, distance from a large body of water.

39
Q

One day in Waterford, CT the weather forecast calls for rain and a temperature of 1°C (34°F). You plan on going to skiing in Killington, Vermont, which has an altitude that is 2,000 feet higher. How might the weather be different in Vermont?

A

It would be colder because it has a higher elevation and you would probably see snow.

40
Q

What variable has the biggest impact on climate in a city?

A

Latitude

41
Q

You are trying to determine the climate of a region, what period of time would you want to see to determine the climate of the region?

A

30 year span

42
Q

What happens to the temperature range of air masses as they move across a continent?What happens to the temperature range of air masses as they move across a continent?

A

It increases

43
Q

What happens to air temperature when air rises from the surface and gains altitude to about 20,000 feet?

A

It cools

44
Q

Name 2 ways that heat can be moved from the equator to the poles.

A

Ocean currents (water) and convection cells (air)

45
Q

Why are rainforests typically found near the equator?

A

More direct sunlight leads to evaporation; the air rises, cools,condenses then causes precipitation

46
Q

Why are deserts typically found at 30° North and 30° South of the equator

A

It is between the hadley and ferrel cells and the air is moving downward, which causes it to warm and be able to hold more moisture. This causes those areas to have little rainfall.

47
Q

Explain why there is a forest on the windward side and a desert on the leeward side of the mountain

A

Lee rain shadow. as air move up the mountain, the air cools causing condensation and precipitation. The opposite happens as the air moves down the mountain.

48
Q

How do greenhouse gases impact temperature of planets

A

They trap heat causing the temperature to increase

49
Q

You are building a cottage in Key West, FL. You want to try to spend the least amount of money on air conditioning. What color should you paint the cottage?

A

White

50
Q

Name the reservoirs where carbon is stored on Earth

A

Air,Water,living things,land
Atmosphere, hydrosphere, biosphere, geosphere

51
Q

Name 2 processes where carbon is removed from the atmosphere

A

Photosynthesis,ocean diffusion,fossil fuel formation,chemical weathering

52
Q

Name 2 processes where carbon is put into the atmosphere.

A

Respiration and decomposition,combustion,volcanism, ocean diffusion

53
Q

Why does burning fossil fuel contribute more carbon dioxide into the atmosphere than burning biofuels like ethanol?

A

Because fossil fuels take a very long time to form the plant used to male the ethanol is undergoing photosynthesis when it grows

54
Q

What percent of light gets reflected when a surface has an albedo of 1

A

100%

55
Q

What do we call the spaces in between rocks and sand grains where water can be stored?

A

Q

What do we call an area of rock that contains well connected pores that allows groundwater to flow through it

A

Aquifer

57
Q

What would happen if you put a raft into the Gulf Stream?

58
Q

Name the fossil fuels

A

59
Q

What latitudes include the tropics?

A

60
Q

What latitudes include the temperate zones

A

23.5 degrees to 66.5 degrees north and south

61
Q

What latitudes include the polar zones?

A

66.5 degrees to 90 degrees north and south

62
Q

What primary feature is used by the Koppen climate classification system?

A

Most commonly found plants in the region, temperature and rainfall

63
Q

What causes the seasons?

A

Revolution around the sun

64
Q

Is El Niño short term or long term climate change?

A

Short term climate change

65
Q

What are the products of the combustion of hydrocarbons?

A

Water and carbon dioxide

66
Q

How does deforestation impact global warming?

A

It decreases photosynthesis causing the concentration of carbon dioxide in the atmosphere

67
Q

Where does El Nino start?

A

Off the coast of peru with weakened trade winds and warmer water in the pacific ocean

68
Q

How is climate different than weather?

A

Climate is long term, weather is short term

69
Q

What part of the Earth gets the most solar radiation?

A

The tropics

70
Q

Temperature, cloud cover, wind speed, humidity, air pressure and wind direction are all factors of what?

A

Weather

71
Q

What causes deep ocean currents?

A
