Water Smart: The Sun, Water Cycle, & Climate - Percolation

The video explains the process of percolation, where water soaks into the ground. It describes how sandy ground allows for fast percolation due to its porosity, while clay-rich ground slows the process. As water percolates, soil and plants filter and clean it. A demonstration using cotton balls and muddy water shows how porosity can be observed. Finally, the video explains that water that percolates into the ground becomes groundwater.

What is the term used to describe the process of water soaking into the ground?

• Percolation

• Evaporation

• Sublimation

• Condensation

Which type of ground allows water to percolate quickly?

• Clay-heavy ground

• Rocky ground

• Sandy ground

• Grassy ground

What role do soil and plants play as water sinks into the ground?

• They filter and clean the water.

• They absorb all the water.

• They prevent water from soaking in.

• They speed up the percolation process.

Which materials are used in the experiment to demonstrate porosity?

• Gravel, water, and a bucket

• Clay, water, and a jar

• Muddy water, cotton balls, and a funnel

• Sand, water, and a sieve

What is water called once it percolates into the ground?

• Runoff

• Surface water

• Rainwater

• Groundwater
