Explanation:
There are four main types of deltas classified by the processes that control the build-up of silt: wave-dominated, tide-dominated, Gilbert deltas, and estuarine deltas.
Answer:
Weathering degrades a rock without changing its location. Erosion, on the other hand, causes rocks -- or particles of rock -- to be carried away from their original locations and deposited elsewhere
Answer:
Option (B)
Explanation:
The fault usually refers to the planar type of fractures that occurs in the earth's crust. Those faults in which the hanging-wall (H.W) block goes down with respect to the foot-wall (F.W) block is considered as the normal fault. This type of fault occurs due to the tensional force or extensional force.
Here, the rocks move in the opposite direction. This movement of blocks results in the release of a certain amount of energy that leads to the occurrence of shallow-focus earthquakes.
Thus, the correct answer is option (B).
The igneous rock, if it has pushed its way, as a magma into the surrounding sedimentary rock such as a sandstone or a limestone and cooled off, will have a relative age as younger than the sedimentary rock. Also, if the igneous rock has altered the sedimentary rock at their contact, then the alteration will have a similar age to the igneous rock age.
South America is in the Western Hemisphere so it is True.
