Which type of soil can retain the greatest amount of water?
one that has low porosity
one that has high porosity
one that has low permeability
one that has high permeability
Which of these circle graphs most correctly shows the approximate proportions of fresh water and salt water on the surface of the earth?
A glass of ice water is shown below before and after it reaches room temperature. Which of the following correctly explains something that occurred in the time between these two images?
As water vapor condensed on the glass, it absorbed energy.
The ice cubes expanded in volume as they melted into liquid water.
The water droplets outside the glass absorbed energy as they evaporated.
Some liquid water inside the glass sublimated into water vapor in the air.
Which of the following is not a way that water reaches Earth’s atmosphere?
Condensation
Sublimation
Transpiration
Evaporation
Which of the following correctly explains why icebergs float in the ocean?
Ice is less dense than liquid water because water contracts when it freezes, filling in open space between molecules.
Ice is less dense than liquid water because there is more open space between molecules in ice than in liquid water.
Ice is more dense than liquid water because there is less open space between molecules in ice than in water.
Water is a polar molecule, so the net positive electrical charges in the water repel the net positive electrical charges inside the iceberg.
A certain percentage of water that falls to Earth’s surface as precipitation each year does not immediately return to the water cycle. Which of the following is the best explanation as to what happens to most of this water?
The water falls into the ocean, where it evaporates back into the atmosphere.
The water is stored as snow and ice on the Earth’s surface.
The water molecules are broken down into hydrogen and oxygen atoms.
The water is absorbed and used by plants.
Which of the following is an incorrect statement about the flow of water through watersheds?
A watershed can be fed by groundwater.
The boundary separating two watersheds is called a divide.
Plant life often alters the flow of water in a watershed by causing erosion.
The gradient of the land can affect the flow of water through a watershed.
Which of the following is the name for all the materials carried by a stream other than the water itself?
Discharge
Flow
Gradient
Stream Load
Which of the following is a measure of the amount of open spaces between the particles of rock and soil?
Porosity
Saturation
Permeability
Precipitation
The table below shows the amounts of different types of surface water on Earth. Based on the table, about how much water is available to provide habitat for wildlife?
just over 3,000 cubic miles
nearly 43,000 cubic miles
about 46,000 cubic miles
close to 6,000,000 cubic miles
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?
how most water on Earth is in the form of water vapor
how land is the main source of water during the water cycle
how the ocean is large enough that it never runs out of water
how the sun is the main source of energy for the water cycle
Which term is used to refer to the path that a river or stream takes?
Divide
Channel
Gradient
Tributary
Some hurricanes originate in the tropical regions of the Atlantic Ocean or Caribbean Sea, and they often travel along the coast of Florida. The figure below shows a hurricane cloud that formed over the Atlantic Ocean. Which two processes would have occurred for the hurricane to form over the ocean?
freezing and condensation
evaporation and precipitation
evaporation and condensation
condensation and precipitation
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?
Sublimation
Melting
Deposition
Freezing
After a day of rain, Samuel 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?
The water was absorbed into the soil.
The water seeped through the ground.
The water evaporated into the atmosphere.
The water slowly trickled to lower ground as runoff.
Hydrogen and oxygen are the two elements that make up water. Which of the following diagrams correctly shows how these elements form a water molecule?
The diagram below shows a side view of several layers of rock below Earth’s surface. Which rock layer would be recharged more quickly than the others?
Layer I
Layer II
Layer III
Layer IV
What percentage of water on Earth is fresh water?
0.5
3
7
18
Which of the following most directly prevents erosion in a watershed?
plant life
soil type
sediment transport
agricultural irrigation
How does the property of cohesion affect the way liquid water behaves?
Water forms droplets whenever possible.
When water freezes, it becomes less dense.
Water retains heat longer than other substances do.
When water vaporizes, it stores more energy than liquid water stores.
