Bodies of Water

By Jackson Dumit

Glaciers

Glaciers are huge masses of ice that flow like very slow rivers. Glacier are flowing ,and they are freshwater. Ten percent of land area is covered with glacial ice. A glacier forms when snow remains in the same area year round where enough snow acculiats and turns into ice. They flow very slowly. Glaciers can move at a rate of fifty feet per a day. There are two main types of glaciers, Alpine glaciers and Contineltal glaciers. Some glaciers look blue because thats the only color glacial ice can't absorb.

Rivers

A river is a larger version of a creek.Rivers are flowing. A river starts at the highest point in the area, mostly hills or mountains. Rivers are freshwater. The end of a river is called the mouth. Rivers usually end flowing into lakes or oceans. A river forms from water moving from a higher altitiude to a lower altitude all due to gravity. When rain falls on the land it either sinks into the ground or becomes runoff which flows downhill to lakes or rivers. Rivers move very fast

Oceans

Oceans are the largest bodies of water of all. A ocean is flowing. Around 71% of the Earth is cover in ocean. There are five oceans Atlantic, Pacific, Indian, Artic, and the Southern ocean. Oceans are saltwater. The largest mountain range in the world is underwater.

Lake

Lakes are freshwater, and stationary. A lake is a large body of water surrounded by land. Lakes form by filling a bowl shaped depression called a basin. Many lakes especially in the northern hemisphere were formed by glaciers that covered large areas of land. A lake can be found on every continent. Lakes may vary in depth, the worlds deepest lake is lake Baikal, in Russia. Lakes exist at many different elevations. The water in lakes are mostly from rain, snow, melting ice, streams, and groundwater seepage.
