River Report



How a river is formed?

A river is formed when rain and snow fall slowly down onto a mountain, because of gravity. Another source of rivers are naturally forming springs. A spring is water that comes from out of the ground. Glaciers also form rivers when they melt. Water interestingly always flows down because of gravity. When a river flows peacefully down a mountain it may hit rocks. Snow, rain, glaciers and springs. These are all possible sources.

Oceans and Seas

Oceans amazingly cover 70% of the world’s surface. The water in the ocean is very salty and unsafe to drink. There are 5 oceans on the planet; the Arctic, pacific, Indian, Atlantic and the Antarctic. Out of all of the five oceans, the Pacific is the biggest covering 30% of the surface of the Earth. A sea is interestingly part of an ocean.
