Study Notes

Eastern Ghats

Spread across the states of Telangana, _____, _____,

Rain Gauge

An instrument used to measure rainfall
Measures the amount of rainfall for a unit area in centimeters

Direction

Mehar traveled from Hyderabad to Bhopal in a _____ direction
Ashok traveled from Lucknow to Chennai in a _____ direction
Regina traveled from Mumbai to Bhubaneshwar in a _____ direction
Weprechu traveled from Kohima to Jaipur in a _____ direction

Map Skills

Use symbols to show physical objects on a map (point, line, area)
Point symbol: used to show Delhi in the map of India
Line symbol: used to show the river Manjeera
Area symbol: used to show the area of Medak or Hyderabad district

Contour Lines

Show the shape and height of the land
The distance between two contour lines depends on the landscape
Steep climb: contour lines are near each other
Gentle slope: contour lines are far apart

Sea Level

Mean Sea Level is the standard height
Sea level is affected by high and low tides
0 meter height is the sea level or Mean Sea Level

River Formation

Rivers start as thin streams in the mountains
As the river flows, it gets bigger and broader
Tributaries are smaller rivers or streams that join a large river
River courses and river valleys are formed through erosion and deposition

River Flow

As the river becomes bigger and broader, its flow gets slower
The river deposits silt and sand on its bed and banks
This causes the formation of plains

Flooding

Floods are caused by a sudden increase in the volume of water reaching a river
Vegetation helps to prevent flooding by allowing water to flow slowly into the river
Vegetation also helps to increase the amount of water that goes into the soil

Soil Erosion

Vegetation prevents soil erosion by reducing the amount of soil carried by rainwater
Without vegetation, rainwater cuts and carries top soil, leading to soil erosion
