Water Cycle and Freshwater

The picture below shows the polar ice caps in the Arctic sea. What will happen to the ice caps if the Sun's energy gets stronger?

• The ice will become much colder, causing

  clouds to form less rainfall.

• The ice will become much harder, causing

  clouds to form more rainfall.

• The ice will become water, then the water will

  become vapor.

• The ice will become vapor, then the vapor will

  become water.

Why is the ice melting in picture Y, but not picture X?

• The Sun's energy is heating the ice and turning

  it into water.

• The Sun's energy is heating the water and

  turning it into ice.

• The clouds are heating the ice and turning it into

  water

• The clouds are heating the water and turning it

  into ice.

If the sky was clear in picture X, then the snow on

top of the mountain would

• take in heat energy from the Sun and turn into

  ice.

• give off heat energy to the Sun and turn into a

  liquid.

• give off heat energy to the Sun and turn into a

  gas.

• take in heat energy from the Sun and turn into a

  liquid.

Where does most of the water evaporation on

Earth come from?

• surface lakes

• transpiring plants

• oceans

• rivers

What would happen if the lamp were removed from this model?

• The clay in the mountain would harden more

  quickly.

• The ice would continue to stay frozen in the cup

  and not change states.

• The water at the bottom of the aquarium would

  evaporate more slowly.

• The temperature of the aquarium would greatly

  increase.

What would NOT happen if another lamp were added to the model?

• The ice would melt more quickly because of the

  extra heat.

• More clay would form and the mound would get

  higher.

• The temperature inside the aquarium would

  increase.

• More water in the aquarium would turn into a

  gas more quickly.

Most of Earth's surface is covered with water. Only 2.5% of Earth's global water is freshwater. Of all the freshwater on Earth, 78% is frozen. Where is most of Earth's water found?

• glaciers

• lakes

• oceans

• rivers

The graph shows the distribution of water on Earth's surface. What can be concluded from this image?

• Most of the freshwater on Earth is found in groundwater.

• Most of the the water available on Earth is drinkable.

• Most of the water available on earth is not drinkable

• Most of the freshwater on Earth is found in oceans.

How does most of the water in the water cycle move from lakes and rivers directly back into the atmosphere?

• precipitation

• respiration

• evaporation

• condensation
