Which of the following choices below BEST describe the natural greenhouse effect?

• When the Earth's surface absorbs energy from the Sun, it radiates that energy back toward space. Greenhouse gases, such as carbon dioxide, trap some of that energy, making the surface cool

• When sunlight bounces off the Earth's surface, greenhouse gases like carbon dioxide reflect it back toward Earth, warming the surface.

• Since the Earth's atmosphere traps sunlight in much the same way that a greenhouse does, an increase in the amount of energy coming in from the Sun is warming the Earth's surface.

• The greenhouse effect is one hypothesis to explain recent measurements that the Earth's surface has been warming, but scientists aren't yet sure what causes it.

What is evaporation?

• The part of the water cycle when the sun heats up water, turning it from a liquid into water vapor or steam. It rises from the ground into the air.
• The part of the water cycle when the water vapor in the air gets cold. The water turns back into a liquid and forms clouds.
• The part of the water cycle when clouds get heavy and can no longer hold the liquid water. This causes the water to fall from the sky to the earth as rain, snow, sleet, or hail.

What is condensation?

• The part of the water cycle when the sun heats up water, turning it from a liquid into water vapor or steam. It rises from the ground into the air.
• The part of the water cycle when the water vapor in the air gets cold. The water turns back into a liquid and forms clouds.
• The part of the water cycle when clouds get heavy and can no longer hold the liquid water. This causes the water to fall from the sky to the earth as rain, snow, sleet, or hail.

How does weather and climate affect a watershed? Circle all that are correct.

• There has been a decrease in the number of droughts, so watersheds have dried up

• There has been an increase in dead zones in watersheds.

• There has been an increase in evaporation which eventually leads to severe flooding in watersheds

• It does not affect watersheds.

Which is a MAJOR cause of acid rain?

• spraying pesticides on crops

• burning fossil fuels for energy

• dumping sewage in rivers

• using Nuclear power stations

Which is NOT caused by acid rain?

• damage to statues

• dying fish

• spread of disease

• weakened trees
