Climate Change

Question 1

Water heats up faster than land. (true or false)

Answer 1

false

Question 2

What is albedo?

Answer 2

The reflectivity of a surface.

Question 3

Why does it take a long time for water to heat up/cool down?

Answer 3

high thermal heat capacity

Question 4

dark surfaces –> low albedo –> absorbs sun/heat (true or false)

Answer 4

true

Question 5

Glaciers have a high albedo. (true or false)

Answer 5

true

Question 6

What is climate?

Answer 6

The weather conditions prevailing in an area in general or over a long period.

Question 7

What is weather?

Answer 7

The state of the atmosphere at a given time and place.

Question 8

The state of the atmosphere at a given time and place.

Answer 8

temperature and precipitation

Question 9

How do bodies of water affect local climate?

Answer 9

Moderates climate because of water’s high thermal heat capacity. (It takes a long time to warm up and a long time to cool down.) Buffers temperatures

Question 10

How do ocean currents affect climate?

Answer 10

Ocean currents act as conveyor belts of warm and cold water, sending heat toward the polar regions (from the equator) and helping tropical areas cool off (from the polar regions), thus influencing both weather and climate.

Question 11

What are the 3 types of energy transfer?

Answer 11

convection, conduction, radiation

Question 12

What is convection?

Answer 12

Heat transfer in a fluid in which hot fluid rises and cold fluid sinks, setting up a cycle (heating through flow).

Question 13

What is conduction?

Answer 13

The transfer of heat through direct contact (heating through touch).

Question 14

What is radiation?

Answer 14

The transfer of energy by electromagnetic waves (from the sun).

Question 15

Name the 3 factors that affect climate precipitation?

Answer 15

prevailing winds, mountain ranges, bodies of water

Question 16

What is the greenhouse effect?

Answer 16

A process that occurs when gases in Earth’s atmosphere traps the Sun’s heat. This process makes Earth much warmer than it would be without an atmosphere. The greenhouse effect is one of the things that makes Earth a comfortable place to live.

Question 17

What is global warming?

Answer 17

A gradual increase in the overall temperature of the earth’s atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, chlorofluorocarbons, and other pollutants.

Question 18

Which holds heat longer, land or water?

Answer 18

water

Question 19

How is Carbon Dioxide added to the atmosphere?

Answer 19

Carbon Dioxide is added to the atmosphere through natural and unnatural sources. These include volcanoes, decomposition, deforestation, burning of fossil fuels.

Question 20

What are fossil fuels?

Answer 20

Fossil fuels are made from decomposing plants and animals. These fuels are found in the Earth’s crust and contain carbon and hydrogen, which can be burned for energy. Coal , oil , and natural gas are examples of fossil fuels.

Question 21

What is the impact on the environment when fossil fuels are burned?

Answer 21

It causes carbon dioxide levels in the atmosphere to rise.

Question 22

Name a non renewable resource.

Answer 22

Coal, natural gas, oil, nuclear

Question 23

Name a renewable resource.

Answer 23

solar, wind, biomass, hydroelectric, geothermal

Question 24

The Greenhouse Effect is caused by _____________________, ________________________, and ____________________.

Answer 24

CO2 (Carbon Dioxide), Water Vapor, Sun’s energy being trapped
