Ramesh Singh's video: Lakes Size Comparison: All About Lakes Hydrosphere 1

A hydrosphere comprises of all the forms of water found on a planet. It can be in the form of liquid, water vapor, or ice. There are around 1.4 billion cubic km of water on earth including lakes, rivers, seas, oceans, groundwater, and glaciers. About 71 percent of the earth’s total surface area is covered with water. A lake is a body of water that is surrounded by land and is larger than a pond. The great lakes of North America are the largest freshwater lakes in the area and second largest in volume. It comprises of Lakes Superior, Lake Michigan, Lake Huron, Lake Erie, and Lake Ontario. The deepest and oldest lake is Lake Baikal in Russia which is 1.6 km deep and is 25 million years old. It is created due to the movement of tectonic plates which created a fault. Water fills up the fault giving birth to the Lake and it contains as much water as all the great lakes combined. Lakes are classified into several types such as tectonic lakes, volcanic lakes, glacial lakes, oxbow lakes, meteorite lakes, etc. Chapters: 0:00 Hydrosphere 1:37 About Lakes 3:23 Largest Lakes Size Comparison 6:25 Types of Lakes ____________________________________________________________________ About the channel: This channel contains advanced educational videos related to different fields of science.
