6th grade Water Unit Review

Sam planned an investigation to determine the conditions that lead to the cycling of water. What factor that drives the cycling of water must be included in Sam's investigation?

• plants and trees in the biosphere

• the surface features of Earth

• water in the hydrosphere

• the energy from the Sun

Corbitt takes a bottle of juice out of the refrigerator. He notices that water begins to form on the outside of the bottle. Which of the following explains why the water started to form?

• Evaporation occurs on the bottle because the room is cooler than the bottle

• Condensation forms on the bottle because the room is warmer than the bottle.

• The bottle is melting because the room is warmer than the bottle.

• The bottle is freezing because the room is cooler the bottle.

Which of the following would cause surface ocean water to have a higher salt content?

• the flowing of a river into the ocean

• the melting of sea ice

• high rates of evaporation and low rates of precipitation

• low rates of evaporation and high rates of precipitation

Which of the following characteristics alters the density of ocean water?

• temperature and wave speed

• salinity and temperature

How do ocean currents on the water's surface transfer energy?

• Currents transfer heat among the tropical latitudes

• Currents transfer heat from deep ocean water to shallow water.

• Currents transfer heat from warm tropical latitudes to cooler latitudes

• Currents transfer heat from the Pacific Ocean to the Atlantic Ocean

Aquifers are sources of

• silica, which is used to make glass and paper products

• oil, which is drilled from the aquifer and used to power homes

• saltwater, which is pushed through turbines to make energy.

• freshwater, which is used for drinking, bathing, and watering crops

Why are oceans a major part of the water cycle?

• because they are large bodies of salt water that easily evaporate salt into the air

• because they are large bodies of salt water that fresh water can be evaporated from

• because the salt water condenses easily to become a gas in the air

• because the salt water runs off onto land to fill lakes and streams

What is the primary cause of water evaporation from Earth's oceans and lakes?

• energy from the Sun

• heat from the surrounding land

• warm air masses from the tropics

• circulation of warm water currents
