Water Smart: Water on Earth - Groundwater

The video explains the concept of groundwater, emphasizing its presence beneath the Earth's surface. It describes the percolation process, where rain and melted snow soak into the ground, forming aquifers. These underground water reserves are often clean enough for drinking, leading to the use of wells to access them. The video also covers how plants efficiently draw groundwater through their roots using capillary action.

What is the process called when rain and melted snow soak into the ground?

• Condensation

• Evaporation

• Sublimation

• Percolation

What determines how far and fast water percolates into the ground?

• The amount of rainfall

• The type of ground cover

• The temperature of the water

• The time of day

What is an aquifer?

• A surface water body

• A weather phenomenon

• A layer of rock that stores water

• A type of plant

How do cities typically access water from aquifers?

• By using a bucket

• By drilling wells and using pumps

• By desalination

• By collecting rainwater

How do plants and trees obtain groundwater?

• By photosynthesis

• By using capillary action in their roots

• By absorbing it through their bark

• Through their leaves
