The Journey of a Raindrop

The Journey旅行 of a Raindrop水滴

Explore the fascinating journey of a raindrop as it falls from the sky, travels through various stages, and eventually returns to the Earth's surface. Discover the science behind this natural phenomenon and its importance in the water cycle.

The Journey of a Raindrop

• Rain is a vital part of Earth's water cycle.

• It starts as evaporation蒸發 from oceans海, lakes湖, and rivers河流.

• The condensation凝結 forms clouds.

• When clouds become saturated, raindrops fall as precipitation.

• They replenish groundwater and fill lakes and rivers.

• Rain is essential for agriculture and supports ecosystems.

Multiple Choice

What is the role of rain in the water cycle?

• To replenish groundwater and fill lakes and rivers

• To create clouds through condensation

• To support agriculture and ecosystems

• To start as evaporation from oceans, lakes, and rivers

Water Cycle:

The Water Cycle

1. Evaporation: Water from oceans, lakes, and rivers turns into vapor due to heat.
2. Condensation: Water vapor cools and turns into clouds.
3. Precipitation: Clouds release water in the form of rain, snow, sleet, or hail.
4. Runoff: Water flows over the land, collecting in rivers, lakes, and oceans.
5. Groundwater: Some water seeps into the ground, becoming groundwater.
6. Repeat: The cycle continues as water evaporates again.

Multiple Choice

Which step in the water cycle involves water turning into vapor due to heat?

• Evaporation

• Condensation

• Precipitation

• Runoff

Water Cycle:

Evaporation: The process in which water turns into vapor due to heat. It is an essential step in the water cycle, where water from oceans, lakes, and rivers is converted into water vapor and rises into the atmosphere. This vapor eventually condenses to form clouds and leads to precipitation.
