Answer:
Option (C)
Explanation:
A barrier island is usually defined as a long and narrow type of land that is dominantly comprised of sand particles and are oriented parallel to the coastal mainland.
The presence of a barrier island protects the coastal rocks from getting eroded by the strong water waves, wind, and tidal effects. This acts as a barrier and there lies a lagoon between the coastal landform and the barrier island.
It plays an important role in the ecosystem as it provides valuable nutrients and minerals, supporting a large number of living species.
Thus, the correct answer is option (C).
Answer:
Some geologic processes happen quickly, while others happen over millions of years.
Explanation:
uniformitarianism and catastrophism are geological terminologies which are used to describe events.
Catastrophism is a term used in geology to explain the theory that the Earth is shaped by sudden occurrences which takes place from time to time,these events don't last long.
Uniformitarianism is a terminology used in geology to explain that the Earth is shaped by gradually occuring events or activities which takes place over time, Uniformitarianism can also be described as GRADUALISM.
The Equator is the imaginary line that encircles the Earth and is equidistant from the North and South Poles.
Answer:
A. is a gravity-driven downslope movement of natural materials.
Explanation:
Mass movement -
It is also called , the slope movement , mass wasting .
it is a process , by which , the sand , rock , soil , regolith move towards downslope by the force of gravity .
It includes , slides , falls , topples , creep .
Mass movement is observed in planets other than Earth , like the Mars , Jupiter , Venus .
Hence , from the given option , the correct option for the definition of Mass movement is ( A ) .
