Semester 2 Earth Science Final Review

What surface would you expect to have the highest albedo?

• a black asphalt road

• The top of a snow capped mountain

• a prairie filled with green grass

• A red tin roof

As part of the greenhouse effect, Earth’s surface radiates heat back into the atmosphere and the atmosphere absorbs this heat. Why do areas near the equator generally radiate more energy back into the atmosphere than areas near the poles?

• Areas near the equator have more clouds in the atmosphere than areas near the poles.

• Areas near the equator receive more incoming solar energy than areas near the poles.

• The greenhouse effect only occurs near the equator.

• The greenhouse effect only occurs near the poles.

Which process causes Earth’s surface to warm?

• the conduction of heat by air above Earth's surface

• the reemitting of solar radiation as infrared waves (heat) by the Earth

• the convection of warm air from the atmosphere

• the reflection of electromagnetic waves off bodies of water

Which is one factor that adds to the greenhouse effect?

• a decrease in the amount of dust in the atmosphere

• a decrease in the amount of water on Earth’s surface

• an increase in gases in the atmosphere that absorb heat

• an increase in the amount of solar radiation that reflects into space

Where does the energy within the greenhouse effect originate?

• from convection within the atmosphere

• from the circular movement of hot and cold air

• from solar radiation entering the atmosphere

• from the conduction of heat from the ground to the air

What event helped spawn the Second Great Oxidation Event by decreasing the amount of harmful ultraviolet light, allowing multicellular plants and animals to emerge?

• Increased production of oxygen, which led to the development of an ozone layer.

• The development of chemosynthesizers (the first organisms on our planet) that started to produce oxygen.

• The Earth continually being struck by meteors, asteroids, & comets.

• The introduction of cyanobacteria that used photosynthesis to produce oxygen.

What event helped spawn the First Great Oxidation Event by having oxygen (O2) levels rise abruptly and hydrogen (H2) concentration decline?

• Increased production of oxygen, which led to the development of an ozone layer.

• The development of chemosynthesizers (the first organisms on our planet) that started to produce oxygen.

• The Earth continually being struck by meteors, asteroids, & comets.

• The introduction of cyanobacteria that used photosynthesis to produce oxygen.

What gas makes up approximately 21% of the present day atmosphere around our planet?

• oxygen

• nitrogen

• carbon dioxide

• hydrogen

Which statement accurately describes the relationship between air pressure, air density, or altitude?

• As altitude increases, pressure increases.

• As altitude increases, air density increases.

• Air pressure and density are lowest at sea level.

• Denser air exerts more pressure than less dense air.
