Cont. Shelf

The underwater edge of a continent. It's that part that extends from Earth's land masses, and it is relatively shallow.

Cont. Slope

A steep slope that seperates the continental shelf from the deep ocean basin. Basiclly, a 200 meter drop to ??? drop. Depending on where you are.

Cont. Rise

The area at the bottom of the continental slope. It is a vast underwater hill made from tons of sediments. All the debris drift down from above, such as decaying plants, animal waste, sand, mud, and rock that have washed into the water from the shore.

Abyssal Plain

Very wide, Very flat sections of the ocean floor, made of layers of sediments.

Trench

A very long, narrow canyon-like depression deep in the ocean floor.

Hydrothermal Vents (Underwater Chimneys)

Hydro thermal vent, called smokers, form at mid-ocean ridges. As scalding magma comes into contcat with icy seawater, it hardens to form these chimneys of rock.

How the wind causes the formation of currents

Wind is the movement of air near Earth’s surface. Wind can be a gentle breeze or a strong gale. The most powerful wind happens during storms called tornadoes, cyclones, and hurricanes. Changes in the temperature of air, land, and water cause wind. The global pattern of prevailing winds is caused by the uneven heating of Earth’s surface.As prevailing winds blow across the ocean, they create surface currents in the water. Both prevailing winds and surface currents appear to curve due to Earth’s rotation. This is known as the Coriolis effect.

Basiclly, this is saying that the wind cause the oceans currents due to the movement of the Earth and heat.
