How are lakes formed?
Lakes form when water collects in large indentations of the earth's surface called lake basins. Basins form in different ways, like in imprints left by moving glaciers, trenches formed from moving tectonic plates, areas upstream of dams, and abandoned parts of rivers.
How are different lakes formed Class 9?
Lakes are formed by the action of glaciers and ice sheets, by wind, river action and by human activities. ... Glacial Lake: A lake formed by melting of glacier is called a glacial lake. Most of the lakes in the Himalayan region are glacial lakes. Wular lake (Jammu & Kashmir) is the largest freshwater lake in India.
What are 3 ways lakes may have been formed?
Natural Processes Leading to Lake Formation
- Tectonic Activity. Many lakes have formed as a result of tectonic movements of the Earth's crust. ...
- Volcanic Activity. Lakes formed by volcanic activity tend to be relatively small. ...
- Other Natural Processes. Many other types of lakes exist.
What is a lake in geography class 9?
Lakes are formed usually as a result of tectonic or glacial activity in a region. It can also be formed by a meandering river or even artificially by human activity. ... Lake Kolleru is officially classified as a wildlife sanctuary. The largest salt water lake in India is the Sambhar Lake in Rajasthan.

What are oxbow lakes Class 9?
An oxbow lake is a U-shaped lake that forms when a wide meander from the main stem of a river is cut off, creating a free-standing body of water. This landform is so named for its distinctive curved shape, which resembles the bow pin of an oxbow.
What is a river system class 9th?
The term drainage describes the river system of an area. Small streams flowing from different directions come together to form the main river, which ultimately drains into a large water body such as a lake or a sea or an ocean.
How many types of lakes are there?
6 Types of Lakes and Their Charactersitics. Lakes are classified depending on how they formed and on the quality of the water (freshwater or saltwater).
What are the six ways that lakes are formed?
This article throws light upon the six ways of formation of lakes. The ways are: 1. Earth Movement 2. Glaciation 3. Volcanic Activity 4. Erosion 5. Deposition 6.
How are lakes classified according to their size?
The simplest classification is based on the dimension o f a lake. Whether a lake is small, big or v ery large. There are several type, kinds and categories of lakes in the world. c) Mixing of water. d) Nature of Inflow-outflow. Tectonic lakes are formed due to tectonic uplif t of a mountain range. These actions can create b owl-
How are lakes formed in a meandering river?
Meanders are when a river flows back and forth along a flat plain. When rain swells various portions of these rivers, new lakes are left behind. Landslides and mudslides block off rivers, which eventually back up even more water upstream of the block.
How are oxbow lakes formed and how are they formed?
An oxbow lake is created after a river swells due to excess rain and then waters recede. Tectonic plates in the Earth's crust pull apart and form natural basins that eventually fill up with rain water. Sometimes, a fault opens near an ocean and a new piece of land closes off part of the ocean to create a new lake.
