What is the water cycle?

Back

The water cycle is the continuous process by which water moves from the Earth's surface to the atmosphere and back, involving processes like evaporation, condensation, and precipitation.

Front

What does evaporation mean?

Back

Evaporation is the process by which liquid water turns into water vapor, usually due to heat from the sun.

Front

What is condensation?

Back

Condensation is the process by which water vapor cools and changes back into liquid water, forming clouds.

Front

What is precipitation?

Back

Precipitation is any form of water, such as rain, snow, sleet, or hail, that falls from the atmosphere to the Earth's surface.

Front

What role does the sun play in the water cycle?

Back

The sun provides the energy needed for evaporation, driving the water cycle.

Front

What is a front in weather terms?

Back

A front is a boundary between two different air masses, which can lead to changes in weather conditions.

Front

What is the difference between weather and climate?

Back

Weather refers to short-term atmospheric conditions, while climate is the long-term average of weather patterns in a specific area.

Front

What is a model in science?

Back

A model is a simplified representation of a system or concept that helps to explain or predict how it works.

Front

What is the significance of the Earth's rotation?

Back

The Earth's rotation on its axis causes day and night and affects weather patterns.

Front

What is the composition of the Earth's atmosphere?

Back

The Earth's atmosphere is composed mainly of nitrogen (78%), oxygen (21%), and small amounts of other gases like carbon dioxide and argon.
