Are you learning 8th grade Earth Science? This quiz can help. This quiz asks questions like the amount of water that infiltrates the ground, how the water cycle is fueled, the primary source of water, where it comes from, and how moisture enters the atmosphere. This quiz will help you with enhancing your knowledge about 8th grade Earth Science.

• 1.

### The amount of water that infiltrates into the ground depends on?

• A.

PERMEABILITY

• B.

POROSITY

• C.

WATER TABLE

B. POROSITY
Explanation
The greater the porosity of the loose materials at Earth's surface and the rocks, the greater the amount of infiltration that can occur. POROSITY- pores, open empty space.

Rate this question:

• 2.

### When no more water can infiltrate it's known to______

• A.

RUN OFF

• B.

FLOOD

• C.

STAY THE SAME

A. RUN OFF
Explanation
Precipitation can flow over Earth's surface as runoff. 1/3 of the precipitation falling on land is returned to the water cycle through a runoff.

Rate this question:

• 3.

### The overall view of a regions weather conditions over a long period of time is called

CLIMATE
PRECIPITATION
Explanation
Definition.

Rate this question:

• 4.

### The water cycle is fueled by solar energy.

• A.

True

• B.

False

A. True
Explanation
The water cycle is fueled by solar energy because the sun's heat causes water on the Earth's surface to evaporate and rise into the atmosphere. This process, known as evaporation, is a crucial step in the water cycle. The sun's energy also powers the condensation of water vapor into clouds and the subsequent precipitation, completing the cycle. Without solar energy, the water cycle would not be possible.

Rate this question:

• 5.

### What is the ultimate source of most water on land?

• A.

Evaporation of rivers

• B.

Evaporation of the small lakes

• C.

Evaporation of the oceans water

C. Evaporation of the oceans water
Explanation
The ultimate source of most water on land is the evaporation of the oceans' water. This is because the oceans cover about 71% of the Earth's surface and contain about 97% of the Earth's water. When the sun heats up the surface of the ocean, the water evaporates and turns into water vapor. This water vapor then rises into the atmosphere and eventually condenses to form clouds. These clouds then release precipitation, such as rain or snow, which falls on the land and replenishes freshwater sources like rivers, lakes, and groundwater. Therefore, the evaporation of the oceans' water is the primary source of water on land.

Rate this question:

• 6.

### Water can be stored or retained.

• A.

True

• B.

False

A. True
Explanation
Water can be stored or retained because it has the ability to be contained in various forms such as lakes, rivers, and reservoirs. Additionally, water can also be stored in man-made structures like tanks and dams. This storage of water is crucial for human consumption, agriculture, and industrial purposes. Furthermore, water can be retained in the ground through processes like infiltration, where it seeps into the soil and is stored in underground aquifers. Overall, the statement is true as water can indeed be stored or retained in different ways.

Rate this question:

• 7.

### What is evapotranspiration?

• A.

The sublimation of ice and snow directly into water vapor.

• B.

The interface between the zone of saturation

• C.

Evaporation

A. The sublimation of ice and snow directly into water vapor.
Explanation
2- water table

Rate this question:

• 8.

• 9.

### Prevailing winds are movements of air over the Earth's surface.

• A.

True

• B.

False

A. True
Explanation
Prevailing winds refer to the dominant direction of winds in a particular region over a long period of time. These winds are caused by the uneven heating of the Earth's surface by the sun, which creates areas of high and low pressure. As air moves from high pressure to low pressure, it generates wind. Therefore, prevailing winds are indeed movements of air over the Earth's surface, making the answer true.

Rate this question:

• 10.

### Two ways that moisture enters the atmosphere.

Evaporation and Transporation
Explanation
Evaporation and transpiration are two processes through which moisture enters the atmosphere. Evaporation occurs when water changes from a liquid state to a gaseous state, typically from bodies of water, such as oceans, lakes, and rivers. Transpiration, on the other hand, is the process by which plants release water vapor into the air through their leaves. Both these processes contribute to the water cycle, where moisture is continuously exchanged between the Earth's surface and the atmosphere.

Rate this question:

• 11.

### When precipitation CAN NOT sink through the ground, it's called

Impermeable
Saturated (full)
Explanation
When precipitation cannot sink through the ground, it is referred to as impermeable. This means that the ground does not allow water to pass through it, resulting in the water accumulating on the surface. Another term that can be used to describe this situation is saturated (full), which means that the ground is already holding as much water as it can and cannot absorb any more. Both terms indicate that the precipitation is unable to penetrate the ground and instead remains on the surface.
