Water Cycle Test Review

Planet Earth is called the blue planet because it has so much water. Water is one thing that drives the weather on Earth. Which of the following is a major energy source that drives the water cycle and helps determine the weather on Earth?

• ocean tides
• energy from the sun
• energy inside Earth's core
• winds in Earth’s atmosphere

An ___________________is an underground layer of rock, sand, or gravel that stores groundwater.

• resevior
• aquifer
• trench
• groundwater

Evaporation and transpiration are two processes included in the water cycle. The energy source that drives these processes is____________

• infiltration
• run off of rain water
• heat from the sun
• convection with in the Earth's mantle

Renewable resources like groundwater and oxygen, are purified when they move through Earth's cycles. Which of the following describes how groundwater is purified or cleaned in the water cycle?

• Surface runoff is purified as it flows through streams and rivers into lakes.
• As water evaporates from oceans, it is purified and becomes water vapor.
• Rain and snow is purified during infiltration through layers of soil and rock.
• When water condenses in clouds, it is purified as precipitation is produced.

During the water cycle, water moves from the air to the ground and then back to the air. Which of the following processes causes water to move from Earth’s surface to the atmosphere during the water cycle?

• evaporation
• sublimation
• condensation
• infiltration

Water is absorbed by the roots of a plant. It travels through the plant to the underside of the leaves. Energy from the Sun hits the leaves, causing the water to be released into the atmosphere. The picture below illustrates this process. What is the name of this process?

• condensation
• evaportation
• precipitation
• transpiration

Which of the following is an example of condensation in the water cycle?

• the formation of icebergs
• the formation of clouds
• the formation of water vapor
• the formation of ground water

All water enters the atmosphere as water vapor. What happens to the kinetic energy of the water molecules when the state of matter changes from a liquid to a gas?

• The kinetic energy increases.
• The kinetic energy decrease.
• The kinetic energy stays the same.
• There is only potential energy in water vapor.

The water cycle is driven by two forces. What are the specific forces?

• Gravity; Potential energy
• Gravity; Kinetic energy
• Thermal Energy; Gravity
• Molecular energy; Radiant energy

_______________________ occurs when the water vapor freezes forming ice crystals.

• condensation
• crystallization
• conduction
• convection
