Ocean currents act much like a conveyor belts, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth's surface.
The South Atlantic Ocean is there. <span />
Answer:
5. pycnocline.
Explanation:
Pycnocline is the rapid change in density of ocean water with depth. With increase in depth, ocean water tends to be denser. The two major factors that determine density in ocean water are temperature and salinity(salt contents). The denser water become in the ocean the more likely it sinks easily . This is one major factor that drive Ocean currents, the process is called thermohaline circulation.
The increase in salinity of ocean water causes an increase in density . This is because the salt become tightly pack and filled the water to make it denser . This simply means an increase in saline content of ocean water causes an increase in the density.
Another factor that affects density is temperature. Water at the surface possesses higher temperature due to direct contact with the sun. Usually, the higher the temperature the less dense ocean water becomes . This is why surface water is less dense. As water becomes warm the molecule disperse, this account for it lower density . Colder water are usually higher in density .
Generally, an increase in ocean depth causes considerable increase in density because of it colder temperature and increased salinity contents.
Pollution to the atmosphere, and the fact that fossil fuels are only a finite resource and could very easily run out, and we wouldnt have anything left to power anything except for renewable sources of energy like solar, wind, geothermal, and hydroelectric.
The answer is (B)
beginning in the 1940s, both the United States and Russia lead the way and successfully testing nuclear weapons
U.S. conducted six atomic tests before Russia developed
their very first atomic bomb (RDS-1) and tested it on the 29th of
August, 1949. Testing these bombs back then for both countries were relatively
infrequent because they did not have very many atomic bombs to spare. The
Trinity was tested on the 16th of July 1945 and yielded around 20 kilotons.
Trinity, which was conducted in New Mexico was tested to give an idea of the
actual size and the after- effects of a nuclear explosion. Operation first
lightning or the RDS-1 also known as Joe 1 in the west was tested on August 29th
1949 and considered this test as the first Soviet nuclear test.
