What can we find on our Earth?

What is the difference between a lake and a river?

Lakes and rivers are both bodies of water, but they have some differences.

Lakes and Rivers

Lakes are usually smaller in size compared to rivers. They are surrounded by land on all sides. In lakes, you might find lily pads floating gracefully and colorful fish swimming beneath the calm surface.

Lakes and Rivers

Rivers, on the other hand, are like long, winding highways for water. They flow through the land, carrying water from one place to another. Many rivers start their journey high in the mountains, where melting snow and rainfall feed their waters, before eventually reaching the vastness of the oceans.

Lakes and Rivers

Both lakes and rivers are important. They provide us with drinking water. Farmers use the water from rivers and lakes for irrigation. These bodies of water offer opportunities for recreation. People enjoy swimming, boating, and fishing in lakes and rivers.
