BIOLOGY - Environment - Water Cycle

The video explains the water cycle, highlighting its stages: evaporation, condensation, precipitation, and collection. It emphasizes the limited amount of water on Earth and how it continuously cycles through these stages. Evaporation occurs from various water bodies and plants, while condensation forms clouds. Precipitation includes rain, snow, sleet, and hail, eventually leading to water collection in bodies like lakes and rivers, repeating the cycle.

What is the main reason the amount of water on Earth remains constant?

• Water is imported from other planets.

• Water is produced by volcanic activity.

• Water is continuously cycled through the water cycle.

• Water is constantly being created by plants.

Which of the following is NOT a source of water for evaporation?

• Lakes

• Puddles

• Mountains

• Plants

What happens to water vapor once it enters the atmosphere?

• It becomes part of the soil.

• It disappears into space.

• It condenses to form clouds.

• It turns into ice immediately.

Which of the following is a form of precipitation?

• Fog

• Dew

• Mist

• Hail

What happens to water after it falls as precipitation?

• It evaporates immediately.

• It remains in the atmosphere.

• It is absorbed by plants only.

• It collects in bodies of water and the cycle repeats.
