Climate

Question 0

Climate

Answer 0

The average of the weather in a region over a long period of time

Question 1

Weather

Answer 1

Atmospheric conditions in a particular location over a short period of time

Question 2

Weather predicting technologies

Answer 2

Weather stations
Weather balloons
Aircraft
Satellites

Question 3

Ice age

Answer 3

When most of earths surface is covered with ice

Often followed by a warm period

Question 4

Evidence of climate change today

Answer 4

Global warming
Rising sea levels
Changes in weather patterns
Changes in seasons
Changes in ecosystems

Question 5

When radiation hits a particle of matter, the radiation may be

Answer 5

ABSORBED by a particle
TRANSMITTED through the particle
REFLECTED off the particle

Question 6

The energy absorbed by earths atmosphere, water, and land is converted into…

Answer 6

Thermal energy

Question 7

Thermal energy

Answer 7

The energy of particles associated with temperature an changes of state

Question 8

Heat sink

Answer 8

A reservoir (ocean) that absorbs and stored thermal energy

Question 9

Proxy records

Answer 9

Stores info and found in natural materials hat give clues to what the climate was like in the past
Ex) ice cores. Tree rings. Coral reefs. Fossils.

Question 10

Albedo

Answer 10

The proportion of the suns radiation that is reflected by a surface. Surfaces with a high albedo reflect more

Question 11

Positive feedback loop between ice and earths surface/average temperature

Answer 11

1. Ice melts
2. Albedo increases
3. Less incoming radiation from sun is reflected
4. More energy is absorbed
5. Earths temperature increases
6. Ice melts

Question 12

Earths climate systems

Answer 12

Keeps global temperature constant

1. Atmosphere (gases)
2. Hydrosphere (liquid)
3. Lithosphere (rocks)
4. Living things (people, plants &amimals)

Question 13

Earths climate systems

1. Atmosphere

Answer 13

1. Troposphere
2. Stratosphere
3. Mesosphere
4. Exosphere
   (Decreasing oxygen)
   -ozone layer

Question 14

Earths climate systems

2. Hydrosphere

Answer 14

• Water cycle
• ice
  
  • ice reflects radiation
    
    • more heat = ice melts = flooding

Question 15

Earths climate systems

3. Lithosphere

Answer 15

• mountains effect air flow
• effects rainfall
  
  • wet coasts and dry interiors

Question 16

Earths climate systems

4. Living things

Answer 16

• plants use CO2
• animals produce CO2
• animals, insects, and bacteria produce methane
• CO2 and methane are greenhouse gasses

Question 17

The greenhouse effect

Answer 17

• a natural process
• gasses and clouds absorb infrared radiation emitted from earths surface and radiate it
• heats the atmosphere and earths surface

Question 18

Anthropogenic greenhouse gasses

Answer 18

• due to human activity
• carbon dioxide
• methane

Question 19

The greenhouse effect

Carbon dioxide

Answer 19

Sources of carbon
-volcanic eruptions
- burning organic matter
- cellular respiration
Carbon sinks
- absorb carbon from the atmosphere and store it in a different form

Question 20

Greenhouse gasses

Answer 20

Any gasses in the atmosphere that absorbs thermal energy

• nitrogen
• carbon dioxide
• methane
• oxygen
• water
