Water on Earth's Surface

What is true of the water cycle?

• It begins when the Sun evaporates water from oceans, rivers, and lakes.

• It begins when groundwater flows into oceans.

• It ends when water falls from clouds to Earth's surface.

• It has no beginning or end.

A student is drawing a model that shows the role of surface runoff in the water cycle. How can the student complete her model to include surface runoff?

• by drawing an arrow from the clouds back to the lake

• by adding in an underground cave and drawing an arrow from the lake to the underground cave

• by drawing one arrow from the clouds to the mountains and another arrow from the mountains toward the lake

• by adding in soil and plants and drawing an arrow from the lake to the soil and another arrow from the soil to the plants

In the water cycle model, the glass jar with water represents the ______.

• body of water
• a cloud
• the atmosphere
• the sun

One day, a small water droplet sat in the ocean, warmed by the Sun. As the heat increased, the droplet began to rise into the sky. This process is called (a)   . As the droplet traveled higher, it cooled down and joined other droplets to form a cloud. This stage of the water cycle is called (b)   . Soon, the cloud became too heavy, and the droplet fell back to Earth as rain. This process is known as (c)   .

• evaporation
• condensation
• precipitation
