A student is doing a science experiment on the stomata of plants. He has a tomato plant. He uses wax to cover all the stomata on the leaves of the plant. After five days, he observes that the plant is wilting. What is the best explanation ?
a) The plant released too much water into the air.
b) The plant was unable to carry out transpiration.
c) Condensation could not occur on the leaves of the plant.
d) The plant was unable to take in water through its leaves.
As water changes state, the water either absorbs or releases energy. Which of these answers is a process that releases energy
a) lake water freezing
b) ice subliming
c) snow melting
d) ocean water evaporating
Which process changes ice directly into a gaseous state?
a) deposition
b) evaporation
c) condensation
d) sublimation
If a warm wind passes over snow, the snow can be heated rapidly. When this happens, the snow can change directly into water vapor without first becoming liquid water. What is the correct term for this process?
a) condensation
b) melting
c) deposition
d) sublimation
After a day of rain, a student observed that a field on his family’s farm was covered in water. The next morning, the field appeared dry. Which of these statements is the LEAST likely explanation of what happened to the water?
a) The water was absorbed into the soil.
b) The water evaporated into the atmosphere.
c) The water seeped through the ground.
d) The water moved to lower ground as runoff.
A weather report stated that rain was likely with some snow and hail also possible. Which statement is NOT true about rain, snow, and hail?
a) They all form in clouds.
b) They are all precipitation.
c) They are all made of water.
d) They are all the same state.
On an island near the equator, the sun's energy causes ocean water to evaporate during the day. In the afternoon, heavy rains fall. This process is repeated during the summer months. What does this example best show?
a) how most water on Earth is in the form of water vapor
b) how land is the main source of water during the water cycle
c) how the sun is the main source of energy for the water cycle
d) how the ocean is large enough that it never runs out of water

a) minerals
b) gravel
c) leaves
d) pebbles
In which part of the water cycle are dissolved solid impurities separated from the water?
a) Evaporation from the ocean
b) Cloud formation in the atmosphere
c) Precipitation from the clouds
d) Water flow from the lake to the ocean
Runoff is most like which of the following?
a) a puff of steam
b) a flowing stream
c) a cloud in the sky
d) an invisible form of water
Which of the following is NOT a way that water reaches Earth’s atmosphere?
a) evaporation
b) sublimation
c) condensation
d) transpiration
A percentage of water that falls to Earth’s surface as precipitation each year does not become surface water or groundwater and does not evaporate back into the atmosphere. Which of the following MOST LIKELY explains what happens to this water?
a) The water falls into the ocean, where it evaporates back into the atmosphere.
b) The water molecules are broken down into hydrogen and oxygen atoms.
c) The water is stored as snow and ice on the Earth’s surface.
d) The water is absorbed and used by plants.
Over 6 billion people on Earth use water every day, yet Earth's water supply remains relatively constant. This is because __________.
a) the sea level is rising
b) water exists in three phases on Earth
c) global warming melts ice to replace water that is used
