Test: Water - Grade 6 MCQ

Evaporation of water takes place faster in hot condition. 

In hot conditions the water heats up and evaporates. 

Water is a natural resource that can be considered both exhaustible and inexhaustible depending on context:

• Inexhaustible: In the broadest sense, water is considered inexhaustible because it is part of the Earth's hydrological cycle, where it is continuously recycled through evaporation, condensation, and precipitation.

• Exhaustible: Locally or in specific regions, water can be exhausted or depleted due to overuse, pollution, or mismanagement, leading to water scarcity.

Therefore, the best choice is:

Exhaustible as well as inexhaustible

Water above the 100⁰C is in gaseous state in form of water vapour.

Of the total amount of water present on the earth, the water available for human use is about 1% only. The other 99 percent is in the oceans, soils, icecaps, and floating in the atmosphere

Dew is the condensation of water vapour near the earth’s surface due to low temperature.

About 70% of our body consists of water.

River and lake are a common source of drinking water in cities and towns.

Any form of water that fall from the clouds is known as precipitation . Their are several form of precipitation such as rain, snow, hail and sleet.

No rain or very less rain in an area causes drought.

Fast Moving air is called wind.
Wind is caused by differences in the atmospheric pressure.
When a difference in atmospheric pressure exists, air moves from the higher to the lower pressure area, resulting in winds of various speeds.

Water is a renewable natural resource as it can be recycled naturally and can be reused again and again.The five major renewable energy resources are solar, wind, water (hydro), biomass, and geothermal.

Excessive rain causes flood in a particular area, which causes damage to  life and property. 

At high humidity, high amount of water vapours are already present in the environment and hence evaporation occurs slower.

Changing of water into water vapour is called as evaporation, it occurs at at high temperatures. 

During transpiration, plants loose water in form of water vapour through stomata.

Water is essential for life as it help in digestion, transportation and excretion etc.

Most of the water is available to us as ground water inside the earth crust.

Clothes dry up in sun due to evaporation of water by solar energy.

Water is compound of hydrogen and oxygen element in fixed ratio.

Cyclic flow of water in different state is called water cycle that includes, evaporation, condensation and raining.
