Answer:
A trench forms in an underwater subduction zone, often near continental boundaries.
Explanation:
Trenches are often found close to continents because of the subduction boundaries in which a plate made of oceanic crust slides underneath a less dense plate made of continental crust. The downward movement of the denser oceanic plate causes the formation of a deep underwater chasm. It is important to note that near divergent oceanic plate boundaries, the separating plates form an underwater ridge, not a trench.
Geologically, a high island or volcanic island is an island of volcanic origin. The term can be used to distinguish such islands from low islands, which are formed from sedimentation or the uplifting of coral reefs (which have often formed on sunken volcanos).
I think one of the statement here is erroneously written since A and B is the same statement. It should be that one choice is that "<span>Saltwater freezes at a lower temperature" and this is the correct answer. Saltwater experiences a freezing point depression due to the salt in the solution.</span>
Answer:
wave base is the highest depth at which the route of a water wave creates substantial movement of water.
Wave height is the lateral distance between the waves and the wave's crest
Explanation:
In physical oceanography, the wave base is the highest depth at which the route of a water wave creates substantial movement of water. For water depths greater than the base of the wave, the underlying sediments and the seabed are no longer disturb by the above wave motion.Wave height is the lateral distance between the waves and the wave's crest from taken from bottom of the trough.
Answer:
the answer will actually be A equal to it's diameter at the equator
