Answer:
The correct answer is A. Texture
Surface ocean currents aredriven by winds that blow in certain patterns. They are caused by the Earth’sspin and the Coriolis effect. Evaporation adds water to the atmosphere. It isthe change from liquid to gas wherein liquid molecules tends to go the gasphase and increases the number of molecules.
Surface currents in the ocean are primarily driven by wind. However, other factors such as water density, salinity and temperature can also influence these currents. An example is the Gulf Stream in the Atlantic Ocean.
Surface currents are primarily driven by wind. The wind creates friction with the water's surface, causing it to move in the same direction as the wind. However, other factors such as water density, salinity and temperature can also influence the direction of surface currents. For example, when the water in a particular area is unusually dense or salty, or when the water temperature changes, the water may move in a certain direction, causing a surface current.
For example, the Gulf Stream, a warm ocean current in the Atlantic Ocean, is primarily driven by prevailing winds, but its path is also influenced by changes in water temperature and salinity.

B) desalinization of salt water from the Persian Gulf.
C) importing water using the same ships that transport oil.
D) pumping water from the Black Sea through an overland pipeline.
Countries which border the Persian Gulf such as Kuwait have very limited fresh water supplies, and many are forced to search for water from other sources such as desalinization of salt water from the Persian Gulf. Therefore, the option B holds true.
Desalinization can be referred to or considered as the process of treatment of water such that the salt contents present in the salty water are eliminated.
By the way of this process, water becomes safe for consumption and usage. It is an alternative for countries that have limited supplies of fresh water. This process is used extensively in the countries surrounded by the Persian Gulf.
Therefore, the option B holds true and states regarding the significance of the desalinization.

b. heat
c.extreme pressure
d. weathering
The option B is correct.
The primary agent of contact metamorphism is heat.
Further Explanation:
Contact Metamorphism:When magma is injected towards the surrounding rock, the changes that take place are referred as Contact Metamorphism.
The greater changes take place when the magma touches rock because the temperatures roses as the distance between the boundary and the magma decreases and reaches the highest when it touches the rock or the boundary. The igneous rocks that are formed around from the cooling of the magma arereferred as a metamorphosed zone or a contact metamorphism aureole.The change that occurs is due to chemically active fluids, heat and pressure.
The ore minerals are formed by the process of metasomatism near or at the contact zone. The aureoles show different degrees of metamorphism spreading from the contact area to metamorphosed rock.Therefore,the primary agent of contact metamorphism is heat.
Therefore, the option B is correct.

The primary agent of contact metamorphism is:
(B) Heat
Contact metamorphic rocks are formed due to the influence of magma intrusion at very high temperatures. The temperature is very high because it is located close to the magma. The word metamorphic was taken from the Greek words meta and morph. Meta means change, and morph means form. So, we can conclude that metamorphism is the process of changing rock form.
The primary agent of contact metamorphism is the heat. High temperatures come from magmas injected in the surrounding solid rock. Marble is one of the examples of contact metamorphic process. It is created from limestone that has been subjected to heat.
Besides the contact metamorphism, there are two other processes such as dynamo metamorphism, and pneumatolytic metamorphism. Dynamo metamorphism is influenced by high pressure, but pneumatolytic metamorphism is influenced by gases and chemicals.
