D) blow to the right in Northern hemi-sphere and to the left in Southern hemisphere.

Because of the impact of Earth’s rotation on its own axis, the winds move slightly to the right in the northern hemisphere and to the left in the southern hemisphere. This effect is called the Coriolis effect.

The apparent curving motion of anything, such as wind, caused by Earth’s rotation. It was first described in 1835 by French scientist Gustavo- gasped Coriolis.

This is the region where the temperature is neither very hot nor cold. This region lies between 23 /2°N to 66>/2°N and 23’/2°S to 66 1/2°S.

An anti-cyclone is a high pressure system with winds blowing clockwise in the Northern hemisphere and anticlockwise in the Southern Hemisphere. An anti-cyclone may form wherever air sinks, the condition that creates high pressure. Winds begin to blow outwards form the high pressure area.

The vertical or near vertical moving air is called air current.

Equatorial type of climate.

These are storms which form vey suddenly on land. The highest wind speeds on Earth occur .in tornadoes, sometimes reaching 500km/hr. They are most common and most violent in the U.S.A.

If air moves very fast and blows the things around, it is called storm

Southern and eastern USA.

Australia is Will-willy blows.

China is a typhoon existing.

The upper portion of the Thermosphere has uneven composition of gases and hence it is referred as “Heterosphere”.

The Heterosphere consists of two thermal layers called Thermosphere and Exosphere.

The gas molecules in the air constantly push each other or any other object that comes their way. This push affects them exert together on any other object is described as Air pressure.

When air is hot the pressure becomes low and when it is cool air pressure increases.

Subtropical high pressure belt is known as Horse latitudes.

The low-pressure belt at the earth’s surface around the equator is called the equatorial low-pressure belt or the Inter-Tropical Convergence Zone.

1. With little Water and food left for humans, sailors used to throw the horses into the sea in order to make the vessels lighter.

2. Henceforth these belts (or) latitudes are called as “horse latitudes”.

Coriolis effect is maximum at the Poles

The Coriolis effect is ‘O’ at the Equator

(C) Nitrogen

The volume of carbon dioxide in atmosphere is 0.03%

C) Equatorial low-pressure belt

Inter-Tropical Convergence Zone: The low pressure belt around the equator is called the Equatorial low-pressure belt or the Inter Tropical Convergence Zone.

Correct answer is: (a) Insolation

The atmospheric pressure is measure by means of an instrument known as ‘Barometer’.

Water that has condensed onto objects near the ground when their temperatures have fallen below the dew point of the surface air.

To form dew drops, relative humidity should be 100%

Auroras are cosmic glowing lights produced by a stream of electrons discharged from the Sun’s surface due to magnetic storms that are seen as unique multicolored fire works hanging in the polar sky during mid night

The Sun is the chief energy source of the Earth.

In 1772 CE Daniel Rutherford discovered Nitrogen in atmosphere

The blanket of air that surrounds the Earth is called the atmosphere.

 The five atmospheric layers are Troposphere, Stratosphere, Mesosphere, Thermosphere and Exosphere. 

Troposphere: The lowest layer of the atmosphere is the troposphere. The Greek word ‘tropos’ means ‘turn’ or change. The layer extends up to 8 kms at the poles and up to 18 kms at the Equator. The temperature decreases with increasing height. Almost all weather phenomenon take place in this layer. Hence it is called weather making layer. The upper limit of the troposphere is called as tropopause.

Stratosphere: Stratosphere lies above the troposphere. It extends to a height of about 50 km above earth surface. Since this layer is a concentration of ozone molecules, it is also referred as ozonosphere. The temperature increases with increase in height in this layer. Large jet planes normally fly here. The upper limit of the stratosphere is called as stratopause. 

Mesosphere: Mesosphere extends between 50km and 80km. The temperature increases with increasing height. Radio waves transmitted from earth are reflected back to earth from this layer. Most of the meteors nearing the earth, get burned here. The uppermost limit of the mesosphere is the mesopause.

Thermosphere: Thermosphere exists above the mesosphere. It extends to about 600 km. The composition of gases in the lower thermosphere is more or less uniform, hence it is called ‘‘Homosphere”. The upper portion of the thermosphere has uneven composition of gases and hence it is referred as “Heterosphere”. Here the temperature increases with increasing height. Ionosphere is a layer of the thermosphere that contains Ions and free electrons.

Exosphere: The uppermost layer of the atmosphere is called exosphere. This layer is extremely rarefied with gases and gradually merges with the outer space. This zone is characterized by aurora Australis and aurora borealis.

(d) condensation

(a) Nitrogen

(a) Troposphere

The average global surface temperature is 13°C

(c) Mesosphere

Ionosphere is the zone of radio waves because it reflects sound and radio waves back to the earth’s surface.

(D) the thermosphere

B) Thermosphere

Planetary winds are winds that are created in the different Global circulation cells. 

1. Polar Easterlies – blow from pole to 60° 

2. Prevailing Westerlies – blow from 60° to 30° 

3. Trade Winds – blow from 30° to 0° 

These winds transport heat and moisture across the world. But the winds do not distribute heat or moisture uniformly.

The winds that blow continuously and regularly above the world pressure belts are known as Planetary winds.
