As the air rises, it expands and cools. This cooling causes the water vapour in the air to condense in the form of tiny droplets. Vaporization can be defined as the process in which liquid state changes into the vapor state. So, Vaporization and condensation of water vapors does not influence the movement of air.
The effects of topography on the climate of any given region are powerful. Mountain ranges create barriers that alter wind and precipitation patterns. Topographical features such as narrow canyons channel and amplify winds. Rotation and revolution of earth also affect on movement of air.

The envelop of air surrounding the surface of planets is called atmosphere. Earth, Venus and Mars all these planets have their own atmosphere.

The atmosphere of Venus and Mars planet consists of mainly carbon dioxide gas. Due to presence of higher amount of carbon dioxide gas temperature increases very high during day and low during night.

In atmosphere oxygen is found in form of ozone (O₃)and oxygen(O₂). Oxygen is found in lower layers and ozone in ozonosphere.

Biologically important compounds that contain both oxygen and nitrogen is protein and nucleic acid. These compounds contain oxygen and nitrogen besides carbon and hydrogen.

Atmosphere plays a very important role in maintaining the  temperature of earth. If there were no atmosphere surrounding  the earth, then the temperature of the earth increase during day and decrease during night.

Major part of fresh water is located on mountain tops and glaciers in form of ice caps and glacier. Major portion of water found on earth is salty and found in ocean and seas.

Rise is temperature of water due to addition of hot water into it is known as thermal pollution. Thermal pollution causes death of aquatic organisms.

Percentage of total water found as fresh water is only 2.5%. Out of this percent of water most are in form of ice caps and glaciers. The major portion of water is salty and found in ocean and sea.

Soil is mixture of sand particles, humus and other organic substances along with microbes. Different soil has particles of different size. Clay soil has smallest soil particles and thus its water holding capacity is high.
