Water Cycle

What is the water cycle?

• The water cycle is the method of water being transported through pipes in cities.

• The water cycle refers to the way water is used in cooking and cleaning.

• The water cycle is the continuous movement of water on, above, and below Earth's surface.

• The water cycle is the process of water being stored in underground reservoirs.

Answer explanation

The correct choice describes the water cycle as the continuous movement of water on, above, and below Earth's surface, which includes processes like evaporation, condensation, and precipitation, unlike the other options.

What is the main source of energy for the water cycle?

• The sun

• Ocean tides

• The moon

• Wind currents

Answer explanation

The main source of energy driving the water cycle is the sun. It heats water in oceans and lakes, causing evaporation, which moves water vapor into the atmosphere, leading to precipitation and the continuous movement of water.

___________ is the process by which a liquid, such as water, changes into a gas.

Answer explanation

Evaporation is the process where a liquid, like water, transforms into a gas. This occurs when molecules gain enough energy to break free from the liquid's surface, making 'Evaporation' the correct answer.

___________ is the process by which plants release water vapor through their leaves.

Answer explanation

Transpiration is the process by which plants release water vapor through their leaves. It plays a crucial role in water regulation and nutrient transport within the plant.

___________ is the process by which a gas changes into a liquid.

Answer explanation

Condensation is the process by which a gas changes into a liquid. This occurs when gas molecules lose energy and come together to form a liquid, making 'Condensation' the correct answer.

What is the term for water that flows over the ground surface to rivers, lakes, or oceans?

• Runoff

• Infiltration

• Transpiration

• Sublimation

Answer explanation

The term 'runoff' refers to water that flows over the ground surface, eventually reaching rivers, lakes, or oceans. It is distinct from infiltration, transpiration, and sublimation, which describe different water processes.
