Answer:
Option (4)
Explanation:
The earth is comprised of numerous lithospheric plates. This lithosphere is comprised of dozens of major plates and a few minor plates. These plates are constantly in motion over the less dense asthenosphere layer where the rocks tend to flow during deformation. This plate motion takes place due to the creation of convection current in the mantle region as a result of which the plates move under the influence of uprising magma. These currents are formed because of the heat supplied from the core of the earth.
Some of the major plates are Indo-Australian plate, North American Plate, South American plate and the Pacific plate.
Some of the minor plates include the Cocos plate, Nazca plate, and Caribbean plate.
Thus, the correct answer is option (4).

Answer:
Carbon dioxide is released when fossil fuel is burned in the atmosphere. The fossil fuels are made of hydrocarbon and once it is burned in air carbon dioxide is released into the environment.
Carbon dioxide is one of the most important gases present in the atmosphere which constitutes of about 95 per cent of the the whole atmospheric gases.
Carbon dioxide is one of the main green house gases that helps in the absorbing heat from the atmosphere. It makes the temperature suitable for the organism to live on earth.
Carbon dioxide is a waste product of cellular respiration which is released inside the body an is expelled into the outer atmosphere.
