Water Cycle

Front

water that falls from the sky

Back

precipitation

Answer explanation

Water that falls from the sky is known as precipitation. This term encompasses all forms of water, including rain, snow, sleet, and hail, that return to the Earth's surface from the atmosphere.

Front

96 percent of water is stored in this

Back

oceans

Answer explanation

96 percent of Earth's water is stored in oceans, making them the largest reservoir of water. Clouds and rain contain only a small fraction of the total water, while underground water is also significantly less than that in oceans.

Front

Water moves directly to vapor from ice or snow.

Back

sublimation

Answer explanation

Water moves from ice or snow directly to vapor through the process of sublimation. This occurs without passing through the liquid phase, distinguishing it from evaporation, which involves liquid water.

Front

Percentage of water released through evaporation

Back

Ninety

Answer explanation

The correct answer is ninety, as approximately 90% of water is released through evaporation in the water cycle, highlighting its significant role in this process.

Front

What provides most of the energy for the water cycle?

Back

sun

Answer explanation

The sun provides the energy needed to evaporate water, driving the water cycle. Without the sun's heat, processes like evaporation and precipitation would not occur, making it the primary energy source for the water cycle.

Front

the process of water vapor turning into a liquid

Back

condensation

Answer explanation

The process of water vapor turning into a liquid is called condensation. This occurs when water vapor cools and changes back into liquid form, often seen as dew or fog.

Front

Main way water travels to the atmosphere

Back

evaporation

Answer explanation

The main way water travels to the atmosphere is through evaporation, where liquid water transforms into vapor due to heat. This process is essential for the water cycle, unlike condensation, sublimation, or transpiration.

Front

What is the process called when plants release water onto their leaves?

Back

transpiration

Answer explanation

Transpiration is the process by which plants release water vapor from their leaves into the atmosphere. This is distinct from condensation, evaporation, and sublimation, making transpiration the correct answer.

Front

Where is water found in the sky?

Back

clouds

Answer explanation

Clouds are formed when water vapor in the atmosphere condenses into tiny droplets, making them visible. Therefore, water is primarily found in the sky in the form of clouds.

Front

Percentage of water released through transpiration.

Back

ten

Answer explanation

The correct answer is ten, as approximately 10% of water absorbed by plants is released through transpiration. The other options, ninety and twenty-three, do not accurately represent this percentage.
