climate change

Question 1

weather

Answer 1

The atmospheric conditions including temperature, humidity precipitation and wind in a particular location over a short period of time 

Question 2

climate

Answer 2

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

Question 3

components of earths climate system

Answer 3

 atmosphere hydrosphere, lithosphere, living things

Question 4

what is the air we breathe in mostly made up of

Answer 4

Nitrogen gas

Question 5

how is the ozone in the troposphere different than ozone in the stratosphere?

Answer 5

• ozone in troposphere: toxic and offers no UV protection
• ozone in stratosphere: naturally occurring, serves as protective function, absorbs high energy UV radiation

Question 6

what is the region of the atmosphere where weather happens

Answer 6

Troposphere

Question 7

layers of the atmosphere from lowest to highest altitude

Answer 7

troposphere, stratosphere, mesosphere, thermosphere, exosphere

Question 8

Atmosphere

Answer 8

Made of layers of gases surrounding earth

Question 9

hydrosphere

Answer 9

Includes liquid water and lakes, oceans, water vapor, and atmosphere and ice glaciers

Question 10

Lithosphere

Answer 10

Earths rock crust, including land surfaces

Question 11

Living things

Answer 11

all living things on earth are part of the climate system 

Question 12

greenhouse, gas effect

Answer 12

Processes whereby gases and clouds absorb Infared radiation, emitted from earths surface and radiate it, heading to the atmosphere and earths surface

Question 13

carbon sink

Answer 13

A Reservoir that absorb carbon dioxide from the environment and stores in another form
Plants, soil, ocean

Question 14

impact of carbon dioxide

Answer 14

Causes up to 25% of greenhouse effect

Question 15

Impact of water vapour

Answer 15

2/3 of greenhouse effect is caused by this

Question 16

impact of methane

Answer 16

23x more powerful than greenhouse effect

Question 17

impact of nitrous oxide

Answer 17

300x more effective as greenhouse than carbon dioxide

Question 18

impact of ozone

Answer 18

toxic in troposphere

Question 19

anthropogenic

Answer 19

Trapping of lower energy Infared, radiation by atmosphere, as a result of human activity
Carbon dioxide, methane

Question 20

Anthropogenic sources

Answer 20

carbon dioxide - burning fossil fuels
Nitrous oxide - agriculture
Methane - fertilizer
CFCs - refrigeration methods

Question 21

albedo effect

Answer 21

A measure of how much of the suns radiation is reflected by surface

Question 22

Why are photosynthesis and cellular respiration important to the carbon cycle?

Answer 22

photosynthesis removes carbon dioxide from the atmosphere and cellular respiration, adds it to the atmosphere

Question 23

Heat sink

Answer 23

A reservoir, such as the ocean that absorbs in stores, thermal energy 

Question 24

Proxy records

Answer 24

Stores of information in a tree rings, ice, cores, and fossils that can be measured to give clues to what the climate was like in the past

Question 25

Plate tectonics

Answer 25

The theory explaining the slow moving of large plates in the earths crust

Question 26

Continental drift

Answer 26

The theory that earths continents used to be one big supercontinent called PANGAEA

Question 27

Eccentricity

Answer 27

The earth is not perfectly circular

Question 28

Tilt

Answer 28

Earth tilt back and forth

Question 29

Procession of tilt

Answer 29

The earth wobbles

Question 30

what is IPCC

Answer 30

intergovernmental panel on climate change Group of scientist summarize the latest research on climate change

Question 31

actions, government, industries, or businesses can take to reduce greenhouse, gas emissions

Answer 31

Transportation - drive less Energy production - improve energy, efficiency, through new technologies Waste management - compost all organic waste, so it doesn’t go to landfills

Question 32

Changes in the Arctic affecting the rest of the world

Answer 32

albedo effect Release of carbon dioxide Sea levels rising Ocean currents

Question 33

What is clean energy?

Answer 33

Energy coming from generation systems that do not produce any pollution Solar energy, and wind energy 

Question 34

convection current

Answer 34

A circular current in air, that other fluids caused by the rising of warm fluid as cold fluid sinks

Question 35

how do prevailing winds relate to precipitation

Answer 35

as prevailing wins, pass over the ocean, it picks up water vapour and condenses bringing rain

Question 36

thermohaline circulation

Answer 36

The continuous flow of water around the world, oceans driven by differences in water temperatures in salinity

Question 37

problems caused by melting ice glaciers

Answer 37

Rising sea levels Increase in the coastal erosion
