Water, Water, Everywhere: Freshwater

The video tutorial explains the critical role of fresh water as a natural resource, highlighting its scarcity despite the abundance of water on Earth. It differentiates between standing water, such as lakes and ponds, and moving water, like rivers and streams, both of which are vital for ecosystems and human consumption. Additionally, the video delves into groundwater, emphasizing aquifers as underground water storage systems that can be accessed through wells.

Why is fresh water considered a valuable natural resource?

• It is used in industrial processes.

• It is found only in certain parts of the world.

• It is essential for survival and cannot be replaced by salt water.

• It is abundant and easily accessible.

• Stream

• Waterfall

• River

• Lake

What role do streams and rivers play in the ecosystem?

• They are not significant in the ecosystem.

• They are primarily used for recreational activities.

• They serve as sources of drinking water and support diverse ecosystems.
