Answer:

a. Wind is the major cause of surface ocean current

b. Thermohaline  circulation is the major cause of deep ocean current

Explanation:

Ocean currents is said to be the redistribution or movement of water bodies from one point to another.

On a wide scale the major forces or causes behind the ocean current on the surface is wind-driven. The ocean water on the surface and the atmosphere is directly heated by the sun and it produces winds which blows over the ocean surface , transmitting energy through the process resulting to waves and current.

On the other hand the major causes of deep ocean currents is the Thermohaline circulation . This exist due to temperature and salinity(salty) variation . Usually, water having lower temperature (cold) and high salinity content possesses higher density than high temperature (warm) and low salinity content  water respectively.  The higher density water sinks deeper.  The density variation is the major driving force behind deep ocean current in an extensive scale. And this is what we call the Thermohaline circulation.

Answer: The causes of ocean currents include wind, water temperature/salinity and natural disasters.

Explanation:

A current or circulation is the unified movement of water across the ocean. A Surface current affects the topmost layer of seawater and is defined by the direction of the wind  while Deep Currents reach the sea floor though a combination of surface currents and landforms.  

Water temperature and salinity cause currents by changing water density which in turn results in deep ocean currents circulating the seawater.

Other conditions that cause strong currents are storms and earthquakes which introduces particles  into the seawater.

What formed the Great Rift Valley? A. volcanic activity and tectonic movement B. a massive earthquake 200 years ago C. a mountai
GarryVolchara [31]

The great rift valley was formed by violent subterranean forces that tore apart the earth's crust. These forces caused huge chunks of the crust to sink between parallel fault lines and force up molten rock in volcanic eruptions.

Nadya [2.5K]

Sub-Saharan Africa's equatorial area is known as Equatorial Africa. There are 13-14 nations, so I'm guessing you want Ethiopia, Rwanda, Kenya, and Somalia, which are the most well-known. Savannas in the north and south, as well as mountains and tropical rain forests, characterize the landscape.
