***quiz #2 -m3 Science - Explaining The Water Cycle

1. What is the major source of energy that drives the water cycle?

The major source of energy that drives the water cycle is the Sun. The Sun's energy heats up the Earth's surface, causing water to evaporate from bodies of water and land. This water vapor then rises into the atmosphere where it cools and condenses to form clouds. Eventually, the condensed water droplets fall back to the Earth as precipitation, completing the water cycle.

2. Give the name of the process that is occuring at #4 in the diagram.

The process occurring at #4 in the diagram is precipitation. Precipitation refers to the process where water vapor in the atmosphere condenses into liquid or solid form and falls to the Earth's surface. In this case, the term "precipitation, precipitation" is likely repeated to emphasize that the process happening at #4 is indeed precipitation.

3. Complete the following sentence with one word.

Water vapor condenses on tiny particles of dirt, dust, clay, pollen, or pollutants to form
____________________________.

Water vapor condenses on tiny particles of dirt, dust, clay, pollen, or pollutants to form clouds. Clouds are formed when water vapor in the air cools and condenses into visible water droplets or ice crystals around these particles. The word "clouds" is used in both singular and plural forms to refer to the collective mass of condensed water vapor in the atmosphere.

4. Which of the following is not a major process of the water cycle?

Perspiration

Condensation

Evaporation

Precipitation

Perspiration is not a major process of the water cycle. The water cycle involves the continuous movement of water on, above, and below the surface of the Earth. It includes processes such as evaporation, where water changes from a liquid to a gas, condensation, where water vapor condenses to form clouds, precipitation, where water falls from the atmosphere to the Earth's surface, and runoff, where water flows over the land surface into rivers and eventually back to the oceans. Perspiration, on the other hand, is the process by which sweat is released from the sweat glands of the skin to regulate body temperature in humans and other mammals. It is not directly related to the water cycle.

5. On Which of the following days will the process of evaporation be fastest?

Cold day

Hot day

Cloudy day

Rainy day

On a hot day, the process of evaporation will be fastest. This is because high temperatures increase the kinetic energy of water molecules, causing them to move faster and escape into the air more easily. As a result, the rate of evaporation is higher on hot days compared to cold, cloudy, or rainy days.

6. The hydrologist is the scientist who studies water.
Which of the following is another name for the water cycle?

Groundwater cycle

Carbon -water cycle

Hydrological cycle

El Nino cycle

The hydrological cycle is another name for the water cycle. This cycle refers to the continuous movement of water on, above, and below the surface of the Earth. It involves processes such as evaporation, condensation, precipitation, and runoff. The water cycle is crucial for maintaining the Earth's water supply and regulating the distribution of water across different regions.
