<u>Answer:</u>
A method of transferring certain portions of the globe to a flat map is a projection is true.
<u>Explanation:
</u>
- In order to protrude down a part seen on the globe on a flat sheet of paper, it is mandatory to make certain adjustments in order to keep the angular and linear measurements intact and undisturbed.
- This process of taking down a part of the globe on a flat sheet of paper is referred to as 'projection'.
- For this projection to be accurate, it is primarily necessary to provide for the differences in angles and distances that may possibly occur depending on which part of the globe is to be projected.
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.
