The water cycle describes the movement of water on Earth. About 96% of water is saltwater found in oceans while the remaining 4% is freshwater. Where would the majority of freshwater on Earth be found?
- A.
Groundwater and aquifers
- B.
Swamps and wetlands
- C.
Icecaps and glaciers
- D.
Lakes and rivers
Correct Answer
C. Icecaps and glaciersExplanation
The majority of freshwater on Earth would be found in icecaps and glaciers. Icecaps and glaciers hold a significant amount of freshwater in the form of ice. This frozen water slowly melts and contributes to the freshwater sources such as lakes and rivers. Groundwater and aquifers also hold a large amount of freshwater, but they are not the majority compared to icecaps and glaciers. Swamps and wetlands are important ecosystems, but they do not contain a significant amount of freshwater.Rate this question:

Where is most of Earth's available freshwater stored?
- A.
Underground
- B.
The atmosphere
- C.
Lakes and rivers
- D.
Icecaps and glaciers
Correct Answer
A. UndergroundExplanation
Most of Earth's available freshwater is stored underground. This includes water that is found in aquifers, which are layers of permeable rock or sediment that hold water. Underground water sources, such as wells and springs, are important for supplying drinking water to human populations and supporting ecosystems. This water is replenished through processes like rainfall and snowmelt, which slowly percolate through the ground and recharge the aquifers.Rate this question:

What land use would be the best choice for watershed drainage?
- A.
Mall
- B.
Wetland
- C.
Recreational area
- D.
Parking lot
Correct Answer
B. WetlandExplanation
A wetland would be the best choice for watershed drainage because wetlands have the ability to absorb and retain large amounts of water. They act as natural sponges, slowing down the flow of water and allowing it to gradually seep into the ground. Wetlands also help filter out pollutants and improve water quality. Additionally, they provide habitat for a variety of plant and animal species.Rate this question:

Which of the following practices is not a good way to conserve water?
- A.
Take showers that last 5-10 minutes
- B.
Wash only full loads of laundry
- C.
Keep the water running while washing dishes
- D.
Turn the water off when brushing teeth
Correct Answer
C. Keep the water running while washing dishesExplanation
Keeping the water running while washing dishes is not a good way to conserve water. This practice leads to unnecessary water wastage as the water continues to flow even when not actively being used. To conserve water, it is recommended to turn off the tap while washing dishes and only turn it on when necessary.Rate this question:

How can the atmosphere be considered part of the hydrosphere?
- A.
It is a source of water.
- B.
It blocks ultraviolet rays from the sun.
- C.
It contains the oxygen necessary for life on Earth.
- D.
It traps pollutants that would otherwise harm the earth.
Correct Answer
A. It is a source of water.Explanation
The atmosphere can be considered part of the hydrosphere because it contains water vapor, which is a source of water. Water evaporates from bodies of water and rises into the atmosphere, where it condenses and forms clouds. These clouds can then release water in the form of precipitation, such as rain or snow, which replenishes the water in the hydrosphere. Therefore, the atmosphere plays a crucial role in the water cycle and contributes to the overall water balance on Earth.Rate this question:

Which best explains why so little of the water on Earth is available for human use?
- A.
97% of total water on Earth is freshwater, and most of the remaining 3% is salt water in the ocean basins
- B.
97% of total water on Earth is salt water, and most of the remaining 3% is freshwater frozen in ice caps and glaciers.
- C.
97% of total water on Earth is freshwater, and most of the remaining 3% is salt water found in underground aquifers.
- D.
97% of total water on Earth is salt water, and most of the remaining 3% is freshwater found in lakes, rivers, and ponds.
Correct Answer
B. 97% of total water on Earth is salt water, and most of the remaining 3% is freshwater frozen in ice caps and glaciers.Explanation
The answer correctly states that 97% of the total water on Earth is salt water. This leaves only 3% of water as freshwater. Additionally, it mentions that most of this remaining 3% is frozen in ice caps and glaciers, making it inaccessible for human use. This explanation highlights the limited availability of freshwater for human consumption due to the majority of it being locked up in frozen form.Rate this question:

Slightly more water on Earth today
- B.
Significantly less water on Earth today
- C.
Significantly more water on Earth today
- D.
About the same amount of water today
Correct Answer
D. About the same amount of water todayExplanation
The statement "About the same amount of water today" suggests that the amount of water present on Earth today is similar to the amount that was present millions of years ago. This means that there has not been a significant increase or decrease in the overall amount of water on Earth over time.Rate this question:

When referring to groundwater, (1)___ refers to the volume percentage of pore space that can fill up with water, whereas (2)____ refers to the ability of water to flow through rock.
- A.
Permeability, porosity
- B.
Permeability, infiltration capacity
- C.
Porosity, infiltration capacity
- D.
Porosity, permeability
Correct Answer
D. Porosity, permeabilityExplanation
Porosity refers to the volume percentage of pore space that can fill up with water, while permeability refers to the ability of water to flow through rock. In other words, porosity represents the amount of empty space within a rock or sediment that can hold water, while permeability describes how easily water can move through that rock or sediment.Rate this question:

Which statement best explains the reason some insects can walk across the surface of a lake?
- A.
Water is a polar molecule, and its adhesiveness causes good capillary action.
- B.
Water is a non-polar molecule, and its cohesiveness causes good capillary action.
- C.
Water is a polar molecule, and its cohesiveness causes high surface tension.
- D.
Water is a non-polar molecule and its adhesiveness provides high surface tension.
Correct Answer
C. Water is a polar molecule, and its cohesiveness causes high surface tension.Explanation
Water is a polar molecule, meaning it has a positive and negative end. This polarity allows water molecules to attract and stick to each other, creating cohesion. Cohesion is the force that holds molecules of the same substance together. In the case of water, this cohesion creates high surface tension, which allows some insects to walk across the surface of a lake without sinking.Rate this question:

Which best describes the process by which water from the ocean enters the atomosphere?
- A.
Infiltration
- B.
Precipitation
- C.
Evaporation
- D.
Condensation
Correct Answer
C. EvaporationExplanation
Evaporation is the process by which water from the ocean enters the atmosphere. It occurs when the sun's heat causes the water on the surface of the ocean to turn into water vapor, which then rises into the atmosphere. This process is essential for the water cycle, as it allows water to move from the Earth's surface to the atmosphere, where it can later condense and form clouds, leading to precipitation.Rate this question:

Which best explains the relationship between water stored in the ocean and water stored in groundwater?
- A.
Water stored in ground water enters the ocean directly as discharge, but ocean water does not enter groundwater
- B.
Water stored in the ocean remains separate from water stored in groundwater, and the two sources of water do not interact
- C.
Water from the ocean enters groundwater directly through the soil by infiltration, but groundwater does not enter the ocean water
- D.
Water from the ocean evaporates condenses, and forms precipitation which enters groundwater through the soil by infiltration, but groundwater enters the ocean directly as discharge.
Correct Answer
D. Water from the ocean evaporates condenses, and forms precipitation which enters groundwater through the soil by infiltration, but groundwater enters the ocean directly as discharge.Explanation
Water from the ocean evaporates, condenses, and forms precipitation, which then enters groundwater through the soil by infiltration. On the other hand, groundwater enters the ocean directly as discharge. This explanation highlights the process of the water cycle, where ocean water evaporates, forms clouds, and falls back to the ground as precipitation. This precipitation then seeps into the ground and becomes groundwater. Groundwater eventually makes its way back to the ocean through discharge, completing the cycle.Rate this question:
