Geography Notes
1. Climate
India has a tropical Monsoon Climate
Factors affecting Climate
Altitude: Temperature decreases with increase in height due to the normal lapse rate. Hill stations have a cooler climate
Climatic Barrier or Climatic Divide
The Himalayas act as a Climatic barrier. They prevent the cold winds of central Asia from entering India and also block the monsoon winds from leaving India.

Relief
The windward side of the Western Ghats receives more rain than the leeward side as winds have lot of moisture and lose their moisture when they enter the leeward side. The leeward side is called the rain-shadow. Mumbai gets more rain than Pune.
The Aravallis are lying parallel to the direction of the South West monsoon winds and therefore Rajasthan and the Thar Desert is a region of the rain shadow.
Meghalaya lies on the foothills of the Gharo Kasi Jaintya hills and receives more rainfall and it is called the windward side of the mountain.
Distance from the Sea
The Sea moderates the climate of the place. Places lying near the sea have a moderate climate. Places lying interior have an extreme climate. Winters are very cold and summers are very hot.

Western Disturbances
Western Disturbances are temperate cyclones originating in the Mediterranean Sea. The enter India and give rainfall to Punjab and Western Uttar Pradesh in winter.

Jet Streams
Jet Streams are upper air circulations and they herald the onset of the monsoon.
Four Seasons Summer Season Season of the South West Monsoon, Season of the Retreating Monsoon, Winter Season

Summer Season
Loo Hot winds called Loo originate in the plains of India and they can cause sunstroke.
KalBaisakhi Norwesters are thunder showers and storms originating in the Assam and West Bengal. Beneficial for growing Jute
Mango showers are summer rainfall occurring in the Southern parts of India. They are beneficial for coffee.
The Sea has high pressure and the land low pressure.

The Season of the South West Monsoon
The Season of the South West Monsoon brings rain to India. There are two branches of the South West Monsoon, the Arabian Sea Branch and the Bay of Bengal Branch.
Major difference : Arabian Sea Branch gives rain only in India. More in Volume
Bay of Bengal Branch divides into two, one branch enters the North East and other goes to Myanmar. Lesser in Quantity.

The Season of the Retreating Monsoon
Pressure conditions change. The sea is warmer and has low pressure. Land has high pressure.
The retreating monsoon brings rainfall to coastal districts of Andhra Pradesh and Tamil Nadu.

The Cold Season
The Cold Season begins. Temperate Cyclonic disturbances occur in the Bay of Bengal and winds blow from the Sea to the Coast of Tamil Nadu and Bangladesh giving rainfall there.

2. Soil
Formation of Soil known as Pedogenesis

Alluvial Soil
Is known as Ex-Situ or transported Soil. Brought down by the rivers. Two types—Kadar and Bangar. Kadar more fertile sandy. Bangar old alluvium less fertile.
Rich in Potash (POT and Ash) Poor in Nitrogen (Night and Trojan)
Suitable for growing rice and wheat

Black Soil
Known as In-Situ Soil or formed in the place of origin (also called Residual soils). Formed by volcanic lava spread.
Hold Moisture. Develops cracks during the dry season.
Good for growing Tobacco and Sugar Cane
Red Soil
Formed by the Weathering of ancient crystalline metamorphic rocks.
Rich in Iron. Poor in Nitrogen (Night and Trojan) Needs fertilizers
Millets pulses and fruits can be grown
Laterite Soil
Formed by leaching, that is washing away of the top soil by rain.
Cannot retain moisture. Poor in Potash (Pot and Ash)
Tea coffee and Rubber are grown.
Soil Erosion
Washing away of the top soil called as Sheet Erosion.
Grooves are cuts formed in the land are called as Rill erosion
Cuts in the land develop into Gullies and is called Gully erosion.
Methods to Conserve Soil
Afforestation: Planting of more trees
Prevention of overgrazing

Ploughing along the slopes of the land.
Contour Bunding
Terracing of slopes.

Solid Waste can contribute to the spread of infectious diseases cholera, malaria and diarrhea.
Effect of water Pollution
Water pollution contributes to typhoid, cholera, hepatitis and various other diseases.
Effect of Mining and Industrial Waste
Industrial pollution can lead to global warming. Water can be contaminated with sludge. Disposal of industrial wastes as landfills is a serious problem.
Minamata disease was discovered in Japan caused to due to the discharge of ethyl mercury.

Effects of Oil Spill
Oil destroys the insulating ability of fur-bearing mammals, such as sea otters, and the water repellency of a bird’s feathers, thus exposing these creatures to the harsh elements. Without the ability to repel water and insulate from the cold water, birds and mammals will die from hypothermia.
