3D Geography

Question 1

What are the factors of longitude? (4)

Answer 1

• Also called meridian
• Highest & lowest value: from 0 - 180 degrees
• Prime meridian : goes through England
• International dateline: 180 degrees

Question 2

What is its significance? (Factor of longitude) (2)

Answer 2

• indicates time
• when the date actually changes

Question 3

How many time zones in Canada?
In China?

Answer 3

• 5.5
• 1

Question 4

What are the factors of latitude? (4)

Answer 4

• Also called parallels
• Highest & lowest value : from 0 (Equator) to 90 degrees
• Revolution: 365 days + 1/4
• There would be no seasons if it was straight

Question 5

Is the tilt always the same?

Answer 5

Yes

Question 6

What are seasons caused by?

Answer 6

The tilt of the planet

Question 7

What creates hot/cold places on the planet?

Answer 7

The angle of the hit of the sun

Question 8

How long is the revolution?

Answer 8

365 days

Question 9

How does the planet rotate and how long does it take to do a full rotation?

Answer 9

• on itself
• 1 day

Question 10

What is insolation?

Answer 10

The amount of solar energy captured by the earth

Question 11

What is the problem with living on Mars?

Answer 11

Not enough atmosphere: -63 degrees

Question 12

What is the problem with living on Venus?

Answer 12

Too much atmosphere: 462 degrees

Question 13

What are the atmospheric layers? (4)

Answer 13

• Troposphere ~ 12 km thick –> Mount Everest, GHG
• Stratosphere –> contains ozone layer
• Mesosphere
• Thermosphere

Question 14

What is the difference between GHG and Global Warming?

Answer 14

GHG are good and is a natural phenomena; GW is bad and is caused by an amplified effect

Question 15

What are the causes of Global Warming? (3)

Answer 15

• More GHG’s than the earth can absorb and recycle
• Too much Methane (CH4)
• Climate change

Question 16

What are the factors of “more GHG’s than the earth can absorb and recycle” ? (3)

Answer 16

• too much CO2 to absorb
• fossil fuels need to stay in the ground instead of being burnt
• need to increase “carbon sinks”, ex.: vegetation –> absorbs extra CO2

Question 17

What are the causes of “too much Methane” ? (2)

Answer 17

• from decomposition of organic matter –> permafrost needs to stay frozen to avoid swampy land that releases methane; cattle mature = problematic (manure + digestion gases = methane)

Question 18

What causes wind (air movement) ?

Answer 18

Principle of convection caused by a difference in temperature

Question 19

What does the convection process produce and where?

Answer 19

Convection cells in the troposphere

Question 20

What are the factors of low pressure zones? (4)

Answer 20

• heated air rises
• within the air, moisture rises too through evaporation
• cloud forms as the H2O condenses
• Precipitation (rain/snow/hail) falls in the zone of rising air

Question 21

What are the factors of high pressure zones? (2)

Answer 21

• as air rises, it cools and travels to away from rising air (L) zones
• cool air : heavier than warm air, so it will drop to the ground
