1.
The Water Cycle is also known as ___________.
Explanation
The Water Cycle is also known as the Hydrological Cycle because it describes the continuous movement of water on, above, and below the surface of the Earth. This cycle involves processes such as evaporation, condensation, precipitation, and runoff, which are all interconnected and contribute to the distribution and availability of water resources on the planet. The term "hydrological" refers to the study of water and its movement, making it an appropriate alternative name for the Water Cycle.
2.
Evection is water moving on land.
Correct Answer
A. False
Explanation
Evection is not water moving on land. It is actually a type of tidal phenomenon caused by the combined gravitational forces of the Sun and the Moon on Earth's oceans. This causes the water to move in a specific pattern, resulting in tidal bulges and variations in sea levels.
3.
What is the meaning of H2O?
Correct Answer
C. Water
Explanation
H2O is the chemical formula for water. It represents two hydrogen atoms bonded to one oxygen atom, forming a molecule of water. Therefore, the correct meaning of H2O is water.
4.
What is the 'water moving in the atmosphere' word?
Correct Answer
Evection
5.
The Water Cycle _____ water.
Correct Answer(s)
A. Recycles
C. Saves
Explanation
The water cycle is a natural process that recycles and saves water. Through evaporation, water from oceans, rivers, and lakes is converted into vapor and rises into the atmosphere. Then, condensation occurs, forming clouds. Eventually, precipitation happens, and the water returns to the Earth's surface as rain or snow, replenishing bodies of water and groundwater sources. This continuous cycle ensures the availability and conservation of water resources.
6.
'Water moving on land' is ______________.
Correct Answer
D. Run-off
Explanation
Run-off refers to the movement of water on the land surface, typically as a result of precipitation. It occurs when the ground is unable to absorb all the water, causing it to flow over the surface and eventually into streams, rivers, and other bodies of water. Run-off plays a crucial role in the water cycle and can have significant impacts on erosion, flooding, and the overall health of ecosystems.
7.
The Water Cycle ends.
Correct Answer
B. False
Explanation
The water cycle does not have an ending point. It is a continuous process in which water evaporates from bodies of water, condenses into clouds, falls as precipitation, and then repeats the cycle. Therefore, the statement "The Water Cycle ends" is false.
8.
97% of our water is in the oceans and seas.
Correct Answer
A. True
Explanation
The statement is true because approximately 97% of the Earth's water is found in the oceans and seas. This water is saline and not suitable for consumption or most human activities. The remaining 3% of water is freshwater, which includes water in rivers, lakes, groundwater, and ice caps.
9.
Run off is connected with land.
Correct Answer
C. True
Explanation
Runoff refers to the flow of water that occurs when excess rainwater, meltwater, or other sources of water flow over the land surface. This water then enters streams, rivers, lakes, or other bodies of water. Therefore, it is correct to say that runoff is connected with land as it involves the movement of water from the land to bodies of water.
