The process by which water vapour cools down to liquid state is called :

Match the following :

Conduction	Heat is transferred from the surface of the earth to the outer space in the form of long waves.
Convection	Heat is transferred to the part of the atmosphere close to the hot surface of the earth.
Advection	Heated air expands and rises up.
Terrestrial Radiation	Horizontal transfer of heat by wind.

The difference between the maximum and the minimum temperatures of a day is called :

The balance between insolation and terrestrial radiation is called :

Match the following :

The stage at which the atmosphere is fully saturated with water	Relative Humidity
The critical temperature at which condensation begins	Saturation level
The ratio between the amount of water vapour present in the atmosphere and the total water holding capacity of the atmosphere at a given temperature	Dew Point
In some instances, due to rapid fall in atmospheric temperature, water vapour directly condenses to solid state	Sublimation

Match the following :

The re-radiation of energy from the surface of the earth back to the outer space in the form of long waves	Heat budget
The balance between insolation and terrestrial radiation	Diurnal range of temperature
The difference between the maximum and the minimum temperatures of a day	Terrestrial radiation
The imaginary lines connecting places having equal atmospheric temperature	Isotherms

The re-radiation of energy from the surface of the earth back to the outer space in the form of long waves is called:

What instrument is used to measure wind speed and wind direction?

Which place in Kerala where windmills installed and energy generated?

Air moves from high pressure regions to low pressure regions. Such air movement is called :

As a result of insolation, the atmospheric air expands, becomes less dense and rises up. This air movement is called :

What is the unit of atmospheric pressure?

In the troposphere the temperature decreases at a uniform rate of 1° Celcius for every 165 metres of altitude. This is called :

The zone of transition above the troposphere is called :

The nearest atmospheric layer to the earth surface is:

The part of the atmosphere beyond 90 km from the earth is called :

Kyoto Protocol aims at :

What is the major cause of ozone depletion?

When was the first ozone hole discovered?

When was the Montreal Protocol first enacted?

Which day is celebrated as World Ozone Day?

At an altitude of about 20 to 50 km, the ultra violet rays from the sun splits up ordinary oxygen molecules to single atom oxygen molecules, which reacts with ordinary oxygen molecules to form tri atomic ozone gas. This process is called :

What does the ozone layer protect us from?

What is the main source of greenhouse gases?

What are the main gases that are absorbing terrestrial radiation?

1. water vapor
2. carbon dioxide
3. methane

Gases such as Carbon dioxide, methane, ozone etc. And water vapour present in the atmosphere absorb the terrestrial radiation and retain the temperature of the atmosphere. This phenomenon is called:

Glass panes have the capacity to allow insolation to pass through. By preventing the terrestrial radiations, the temperature required for the growth of plants is retained inside glass constructions. Such buildings are called :

As the fine dust particles in the atmosphere help in cloud formation they are called :

Factors influencing the amount of water in the atmosphere:

1. Rate of evaporation
2. Closeness to the surface water sources such as oceans, rivers and other water bodies.
