Study Notes

Grid Systems

Eastings and Northings are used to locate a point on a grid system.
The points at which vertical and horizontal lines of a grid intersect are called grid references.
When quoting a grid reference, the Easting is mentioned first.
A four-figure grid reference is used to locate large areas like lakes and relief features.
A six-figure grid reference is used to locate a specific point.

Landforms

A valley with a flat wide bottom and steep parallel sides is called a U-shaped valley.
A landform with sides sloping in opposite directions, with a steep slope on one side and a gentle slope on the other side, is called an Asymmetrical valley.
The lowermost part of a U-shaped valley is shown by the trough.
A high-lying tributary valley with a steep slope connecting to the main valley is called a Hanging valley.

Contour Lines

Contour lines that converge represent the slopes of a Hanging valley.
The main difference between an escarpment and a dip slope is the direction of the slope.
Contours on a ridge are usually spaced closely together.
A geological feature formed by the meeting of a river or glacier valley from opposite sides of a mountain range is called a Col.

Drainage

Upward-pointing contours indicate a watershed or drainage divide.

Map Scales

The Representative Fraction (R.F.) is the main difference between map scales.

Forests

Trees in xerophytic forests have very small leaves to conserve water.
The economically valuable tree in xerophytic forests is the Babul tree.
Forests that grow along sea coasts and in wet marshy areas are called Mangrove forests.
The plant characteristic that helps conserve water for a longer period in xerophytic forests is deep roots.
Forests found along the eastern coasts and in the saline swamps of Sunderbans are called Mangrove forests.
The characteristic features of littoral or swampy forests are tangled roots and adapted to saltwater.

Rainwater Harvesting

The main objective of rainwater harvesting is to conserve water.
The advantage of water harvesting that is NOT listed is increased groundwater levels.
Rainwater storing mechanisms in Ladakh are called Zings.
One of the activities aimed at in rainwater harvesting is recharge of groundwater.
Rainwater storing mechanisms in the Western Himalayas are called Kuls.
Rainwater storing mechanisms in the Gangetic Plains are called Ahars and Pynes.
