Climate Change

Question 1

Factors affecting climate change

Answer 1

• latitude
• elevation
• air masses over area
• areas near bodies of water

Question 2

What is conduction

Answer 2

Transfer of thermal energy through direct contact between particles without moving them to new location (TOUCHING)

Question 3

What is radiation

Answer 3

Emission of energy as waves. Substance higher then surrounding will emit radiant energy (infrared radiation) (NOT TOUCHING)

Question 4

What is convection

Answer 4

Transfer of thermal energy through movement of particles from one location. to another (bathtub hot and cold), gasses and liquids (TOUCHING)

Question 5

Layers of atmosphere

Answer 5

Troposphere (life and weather)
Stratosphere (ozone gas and little moisture)
Mesosphere (little gas and air pressure)
Thermosphere (absorbs x-rays and gamma, little gas, auras are)

Question 6

Global warming potential

Answer 6

Measure of ability of gas to trap thermal energy in atmosphere over time

Question 7

Persistence

Answer 7

Length of time gas in atmosphere

Question 8

Coriolis Effect

Answer 8

Moving air to turn right in noters hemisphere and left in southern

Question 9

Natural greenhouse effect

Answer 9

Trap thermal energy for life, water vapour contributes the most, solar radiation absorbed in earths surface and reemitted into atmosphere and thermal energy (absorbed by gas and clouds)

Question 10

Anthropogenic greenhouse effect

Answer 10

Enhancement of natural greenhouse effect from humans, most significant gas is CO2 released from burning fossil fuels

Question 11

Greenhouse gases

Answer 11

Greenhouse gases are gases in the earth’s atmosphere that trap heat.

Question 12

Temperate coniferous

Answer 12

• lots of precipitation
• warm summers, wet winters
• located in canada vancouver
• includes tall coniferous trees, coyotes, bears, lynx

Question 13

Temperate deciduous

Answer 13

• south of boreal
• eastern canada and central (us)
• deciduous trees
• many animals and plants
• MOST PRECIPITAION
• fast decomposition
• includes mice, deer, birds, wolves, trees

Question 14

Boreal

Answer 14

• IN EVERY PROVINCE
• conifers
• south of tundra
• more perception then tundra
• acidic soil
• conifer needles
• birds eating seeds, squirrels, hare, deer, coniferous trees

Question 15

What is climate change

Answer 15

long-term change in climate (average weather over period of time)

Question 16

What is global warming

Answer 16

average annual temp

Question 17

What is weather

Answer 17

day to day environmental conditions

Question 18

Evidence of climate change

Answer 18

• Tree ring analysis
• sedimentary rock (how much carbon was being used and showing former climates)
• ice cores (layers lice showing climate conditions at time)

Question 19

Effects. of climate change

Answer 19

• heat waves
• drought
• wildfires
• storms
• floods
• melting ice
• loss of habitats
• range shifts
