Q

Why does climate change with latitude?

A

As you go farther away from the equator the suns rays get more spread out because the earth is a sphere

Q

What are the four main factors that control climate?

A

Sunlight- brings energy into the system
Volcanic Eruptions- release sulfur dioxide which temporarily reflect sunlight
Greenhouse gases- trap the heat and slow heat from Levi’s g the system
Snow and Ice- Reflect light and heat due to the Albedo affect

Q

Climate is also affected by what 6 factors?

A

Water, ocean currents, snow and ice cover, altitude, latitude, and topography

17
Q

In the Northern Hemisphere water turns what way?

A

Clockwise

18
Q

In the Southern Hemisphere water turns what way?

A

Counter clockwise

19
Q

What is the water current that flows near the east side of the United States? Is it warm or cold? Which direction does it flow?

A

Gulf Stream, warm, north

20
Q

What is the water current that flows near the west side of the United States? Is it warm or cold? Which direction does it flow?

A

California current, cold, south

21
Q

What causes the Coriolis Affect?

A

The earth spinning

22
Q

What does the Coriolis Affect do to weather and hurricanes in the Northern and Southern Hemisphere?

A

Northern- Turns right

Southern- Turns left

23
Q

What are the three main green house gases?

A

Carbon dioxide, water vapor, methane

24
Q

How do these gases produce the Green House Affect and why?

A

Since they are made of three loosely bonded atoms when the energy from the sun hits them the atoms start to shake violently. Eventually it will release the energy but another will pick it up, trapping the heat.

25
Q

What is the Green House Affect?

A

Molecules trapping the heat going into space and holding it in the atmosphere.

26
Q

Why are oxygen and nitrogen good green house gases?

A

They are made of two tightly bonded atoms

27
Q

What would happen to Earth if there was no greenhouse Affect?

A

Earth would be 40°F colder every day. Earth would freeze

28
Q

What is expected for the CO2 levels to due this century?

A

Double

29
Q

What are the main reasons for admitting CO2?

A

Burning fossil fuels, cellular respiration (breathing), forest fires, and vehicles (cars)

30
Q

Main reasons for methane admissions?

A

Farming cows and rice. Also using natural gas

31
Q

What has the IPPC concluded?

A

The cause of climate change is due to burning fossil fuels and land deforestation

32
Q

What are 6 possible outcomes of climate change?

A

Sea level rise, less predictable weather patterns, increase in server weather, melting of the ice caps, species extinctions, and change in crop yield
