Answer:
Sunlight cannot penetrate into the deeper oceanic zone
Explanation:
The oceans are extensively large bodies of water and are comprised of varying depth from place to place. The equatorial and the tropical region receives the maximum amount of sunlight as a result of which the ocean surface temperature rises significantly. So, the surface water up to a depth of about 200 to 300 meters below the sea level remains warm, as sunlight can easily penetrate in this zone.
But, at a depth more than about 300 meters to a depth of 1000 meters, this sunlight cannot penetrate and due to this reason the water in this zone remains cold enough. Thus, the temperature of the ocean water decreases with the increasing depth.
Answer:
gah... tectonic shift or plate motion
Explanation:
The hat from radioactive processes within the planet's interior causes the plates to move, sometimes toward and sometimes away from each other.
Answer: Slab Pull
Explanation:
Whilst I was unable to find the options for your question I believe the answer to be the Slab Pull.
Slab Pull refers to the force exerted by an oceanic plate sinking into the mantle.
The Slab Pull happens because the oceanic plate is colder and denser than the hotter mantle and this difference causes the plate sink further and as it does so it pulls the rest of the plate along with it in a process called Subduction. This is why the question called it a Subducting Plate.
I have attached a diagram showing the process.
