Water Cycle Quiz Ultimate Trivia Questions!

1. How much of the Earth's surface is covered in water?

30%

50%

70%

15%

70% of the Earth's surface is covered in water. This is a well-known fact supported by scientific research and observations. The Earth is often referred to as the "Blue Planet" because of its vast oceans and seas. The remaining 30% of the Earth's surface is comprised of landmasses, including continents and islands. The high percentage of water coverage is due to the presence of large oceans like the Pacific, Atlantic, Indian, and Southern Ocean, as well as numerous smaller bodies of water.

2. Name another stage of the basic water cycle, other than evaporation.

Another stage of the basic water cycle 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 the form of rain, snow, sleet, or hail. This stage is essential for replenishing the Earth's water supply and plays a crucial role in maintaining the water cycle.

3. What is the water cycle powered by?

Moon

Clouds

Sun

Oceans

The water cycle is powered by the Sun. The Sun's heat causes water on the Earth's surface to evaporate and rise into the atmosphere as water vapor. This water vapor then cools and condenses to form clouds. Eventually, the clouds release the condensed water in the form of precipitation, such as rain or snow. This water then flows into rivers, lakes, and oceans, completing the water cycle. The Sun's energy is crucial in driving this continuous cycle of evaporation, condensation, and precipitation.

4. What is it called when the water vapour goes up into the clouds?

Evaporation is the process in which water changes from a liquid state to a gas state, forming water vapor. When water evaporates from bodies of water or moist surfaces, it rises into the atmosphere and can eventually condense to form clouds. Therefore, the process described in the question is evaporation.

5. How much of the Earth's water is fresh?

10%

65%

3%

25%

Only 3% of the Earth's water is fresh. The majority of the Earth's water, about 97%, is saltwater found in the oceans. This small percentage of fresh water is mainly found in glaciers, ice caps, and underground aquifers. It is a limited and valuable resource that is essential for various purposes such as drinking, agriculture, and industrial use.

6. Approximately 50 per cent of the world's lakes are located in Canada. True or False?

True

False

Canada is known for its vast number of lakes, making it the country with the highest number of lakes in the world. With over 2 million lakes, Canada accounts for approximately 50 percent of the world's lakes. Therefore, the statement is true.
