Weathering causes the disintegration of rock near the surface of the earth. Plant and animal life, atmosphere and water are the major causes of weathering. Weathering breaks down and loosens the surface minerals of rock, so they can be transported away by agents of erosion such as water, wind and ice.

This is the correct option. Sun, water, wind and living organisms are the factors that help in the formation of soil.

This is the correct option as sewage is not a non-degradable soil pollutant. It decomposes easily.

It does not provide breeding ground for mosquitoes as this water is below ground and not available to mosquitoes for breeding.

Limestone is a form of carbon and is present in oceans and seas.

The uneven heating of Earth's surface by the sun is also a driving force behind global patterns of winds and precipitation. Rotation of Earth causes the direction of winds and ocean currents to be deflected. Amount of water vapour in the atmosphere and presence of mountains in the path of wind influence the blowing of wind.

Life does not exist on Venus and Mars because the major component of their atmosphere is carbon dioxide.

Urbanisation is not a parameter for determining the quality of soil. Soil quality indicators are physical, chemical, and biological properties, processes, and characteristics that can be measured to monitor changes in the soil.

During roasting, the sulphide is converted to an oxide, and sulphur is released as sulphur dioxide, a gas. 'Roasting' is a step of the processing of certain ores. The technology is useful, but is also a serious source of air pollution.

Air, water and soil are abiotic components.
