The shockwave from an undersea earthquake causes 'ripples' in the ocean which are very large swells. When the bottom of the swell touches land, it must build up higher to maintain it's size. Therefore when it approaches the beach, water is drawn away from the beach to compensate for the ocean depth getting shallower under the tsunami swell. More water is drawn from in front of the swell than behind due to the movement of the swell.
Oceania, which is also known as Oceanica, is a region that is in the center of islands in the tropical Pacific Ocean. From the given choices, the physical geography that best describes Oceania is that is isolated from the rest of the world. The answer is letter D.
The study of geography helps educate people on preserving the climate.
For example , we learn about how deforestation affects the quality of the water, and leads to loosened soil. We learn that we need plants to purify our water.
Deforestation also means lesser plants to give out oxygen and as a result increase global warming, creating extreme changes to climates. This can create droughts and famine and affect food production for the community.
Answer:
Option (C)
Explanation:
Plates here refers to the lithospheric plates, which can be defined as the small or large broken fragments of the earth's crust. These plates constantly moves from one place to another due to the formation of convection current in the mantle. The plates comprises both the oceanic as well as continental crust, which shares three types of distinct plate boundaries such as the convergent, transform and divergent plate boundary.
Thus, the correct answer is option (C).
