Earth's Energy

Test Description: Energy in the earth's system

Instructions: Answer all questions to get your test result.

1) The tremendous amount of heat within Earth's powers

Aocean currents Bweather patterns Call of the above Dplate tectonics

2) The energy stored in fossils fuels originally came from

Agravity BEarth's core Cfusion reaction in the Sun Dfission reaction in the Sun

3) What are the main greenhouse gases?

Awater vapor, nitrogen and methane Bcarbon dioxide, water and methane Ccarbon dioxide, oxygen and nitrogen Dcarbon dioxide, oxygen and water vapor

4) Which gas in the atmosphere has been increasing significantly because of human burning fossil fuels?

Aoxygen Bmethane Ccarbon dioxide Dnitrogen

5) Light that reaches the Earth's surface is either

Areflected and coverted into shorter wavelengths. Babsorbed or refracted back to space Cabsorbed or reflected back into space Dabsorbed or converted into shorter wavelengths.

6) Why is Earth's surface warmer at the equator than at the poles?

Athe Sun is closer to the equator than the poles Bice at the poles keep the surface colder Cthe equator receives more direct sunlight that the poles Dthere is more water vapor at the equator

7) In what are ocean currents and air currents the same?

Acool air sinks, just as coolr or more saline water sinks, and warm air, like water rises. Bwarm air flows more swiftly than cool water, just as warm winds are stronger than cool winds Cboth form currents that flow mostly from cool areas to warm areas Dcool water evaproates and rises into atmopshere

8) Which occurs during a temperature inversion?

Awarm air rises and cold air sinks Bcold air rises and warm air sinks Ca layer of warmer air lies over a cool layer of air. Da layer of cooler air lies over a relatively cool layer of air

9) What is the driving force for surcace ocean currents?

Asalinity Bglobal winds Cthe Coriolis effect Ddensity layering

10) What causes the wind deflection from the north and south poles?

Athe difference of total land mass of the north and south hemisphere Brotation of Earth on its axis Ctilt of Earth's axis Dshape of earth
