It is called surface currents.
Answer:
Surface waves have a longer duration and higher amplitude than body waves.
Explanation:
The stark difference between an earthquake body and surface waves is such that they have longer duration and a higher amplitude compared to body waves.
There are two categories of seismic waves that usually accompanies an earthquake:
- body waves are faster and perpetuate in the subsurface. They reach the seismic station first and are discovered faster.
- surface waves arrives later and they cause the damage produced by most earthquake waves. They perpetuate on the surface.
- surface waves are the love and Rayleigh waves
- body waves are the primary and secondary waves.
When two oceanic plates converge, the denser plate will end up sinking below the less dense plate, leading to the formation of an oceanic subduction zone. Old, dense crust tends to be subduction back into the earth.
Water cycle is effected by pollution, whether it is water pollution or air pollution. Air is polluted by Suspended Particulate Matter and by different harmful gases like Sulphur dioxide etc. These gases react with water vapours in the sky, making the water in the clouds acidic. This acid falls as rain water causing acid rains. This acid falls in ponds, on land, in fields, causing harm to us and to the crops as well as to the fishes or creatures in water. When the water evaporates from ponds, rivers and oceans to make water vapour, the the water in these water bodies becomes more acidic, and again when acid rains occur, this acid again mixes with the water of the water bodies, which already has acid, causing the water to become more concentrated.
Answer:
d. meander scar
Explanation:
Meander scar is the name given to a stream that flows from a floodplain of a larger river. As it flows, it is possible to see this stream swaying tirelessly in all directions giving rise to a series of sinuous and regular curves, creating a watercourse. The meander scar can also originate from a floodplain that changes its channel within a valley.
