Marks : 20 MM Timing: 1hr
01. Define the following
The Earth shows two types of motions. They are rotation and revolution.
Rotation : The movement of the Earth on its own axis is called Rotation. It causes formation of day and night.
Revolution : The movement of the Earth around the Sun. It causes change of seasons.
Orbit : The path followed by earth around the sun
Humidity : The amount of water vapour or moisture present in the air is called
Altitude : height above sea level
Heat Zones : the division of earth according to climate
The Earth is divided into three heat zones. Torrid Zone (hot and humid climate), Temperate Zone (moderate climate) and
Frigid Zone (very cold climate)
Temperature : degree of hotness or coldness
Horizon : a line at which the Earth's surface and sky appears to meet
Weather :
Weather is the day-to-day atmospheric conditions at a particular place. Weather includes changes in temperature, sunshine and rainfall.
Weather changes daily : The climate of a place remains the same year after year.
The factors affecting the climate are: distance from the Equator, altitude, distance from the sea, winds, humidity and rainfall.
Landforms:
Landforms are natural features of the landscape. The main landforms are; mountains, plateaus, plains and deserts.
Mountains :
Mountains are the natural elevation earth's surface. They have peaks.
