Study Notes

Landforms and Geomorphology

A landform is a natural feature on the Earth's surface, shaped by geological processes
Stages of landform development: youth, maturity, old age
Water is the most important geomorphic agent for degrading the land surface
Erosion and deposition affect the surface of the Earth by wearing away and depositing rocks and soil
Two important aspects in the evolution of landforms: tectonic forces and denudation

Fluvial Landforms

A river's course can be divided into three stages: youth, maturity, and old age
During the middle stage, lateral erosion becomes dominant
Meanders grow into deep loops and cut off due to erosion at inflection points, forming oxbow lakes
River terraces are commonly found at the foot of mountains or in valleys
The primary factor responsible for the formation of oxbow lakes is lateral erosion on river banks over gentler slopes

Glacial Landforms

Glaciers occur mainly in polar regions (over 96% of glaciers occur in Antarctica and Greenland)
Glaciers move mainly due to gravity
Formation of glaciers leads to the creation of glacial troughs, which can fill with seawater and form fjords
Moraines are deposits of unsorted till left behind by glaciers
Terminal moraines are long ridges of debris deposited at the end (toe) of the glacier
Glacial drift refers to the layered deposition left behind by a melting glacier

Aeolian Landforms

Deflation causes shallow depressions by persistent movement of winds, called deflation hollows
Wind can lift and remove dust and smaller particles from the surface of rocks, a process called deflation
Dunes are formed when wind direction is constant and the source of sand is an elongated feature at right angles to the wind direction
Barchan dunes are formed when the wind direction remains constant and the source of sand is an elongated feature at right angles to the wind direction
Mushroom-shaped rock formations are formed when wind erodes the surface of rocks
Yardangs are high relief structures in deserts reduced to featureless plains by wind activities

Coastal Landforms

The east coast of India is a deltaic coast, formed by large rivers carrying huge sediments
Barrier bars are formed when long shore drift deposits sand, pebbles, and gravels along the coast
Spits are elongated stretches of sand, pebbles, gravels, etc. deposited along the coast
Fjords are commonly found in Norway and Scotland
Hanging valleys are at higher levels than the main valley and appear hanging over the main valley because of differential erosion
