What is the relationship between the hydrosphere and the cryosphere?

• The hydrosphere is part of the cryosphere.
• The cryosphere is part of the hydrosphere.
• The hydrosphere contains water.
• There is no relationship of the two spheres.

If the hydrosphere changed, other spheres would be affected. What is one possible way that the biosphere might change?

• Increased rainfall would reduce the population.
• Lower lake levels would eliminate habitats.
• Higher lake levels would decrease the amount of available food.
• Reduced rainfall would reduce the amount of available food.

Caroline opened a map to complete her homework by identifying some of the landforms she had learned. She noticed a particular landform reaching from Florida all the way up to Massachusetts. What type of landform is this?

• Plateau
• sand dunes
• coastal plain
• delta

Sarah learned that natural forces are normally either destructive, like a volcano, or constructive, like mountain ranges. However, she read that water can be considered both a constructive and destructive force. In what way can water be a destructive force?

• erosion of landforms
• depositing sediment
• forming a delta
• creating a lake

Felix showed that certain elements of the geosphere and biosphere can affect the amount of water in the water cycle. In what ways do the geosphere and the biosphere add water to the water cycle? Choose the two that apply.

• Rain falls from the clouds.
• Water evaporates from the soil.
• Animals breathe.
• Water evaporates from the ocean.

He showed his dad that water travels through all the spheres. Felix also showed him that the total amount of water on Earth has stayed the same. Why has the total amount of water in the water cycle remained constant?

• More water vapor condenses to keep the cycle in balance.
• More precipitation falls than can evaporate and condense.
• The rate of precipitation and evaporation are in balance.
• The rate of evaporation competes with the balance of precipitation.

Paola is writing an essay about lakes for her science class. She knows that these particular landforms are created in a variety of ways. Which of the following should she include in her essay? Choose the three that apply.

• in rift valleys
• in empty volcano craters
• from melted ice sheets
• by rainfall
• in a watershed

Jasmine breathed against the window pane and noticed that her breath made a spot on it from the water vapor in her breath. Which stage of the water cycle would this show?

• Precipitation
• Evaporation
• Condensation
• transpiration

Ethan watched the news one evening. During the weather section, the meteorologist said a cold front was moving in and then showed a picture of the front. How will these two air masses interact, and what kind of weather will they bring?

• The warm air rises above the heavier cold air and this front brings clear skies.
• The warm air rises above the heavier cold air and this front brings severe weather.
• The cold air rises above the heavier warm air and this front brings light rain.
• The cold air slides under the warm air and the front becomes occluded.
