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.
Aegean Sea, the Black Sea, the Caspian Sea and the Ural River
All water boundaries
My geography teacher was telling us as well it is known as the Eurasian boundary as well
Answer:
1. hydrogen Nitrogen Lead Mercury
2. Phytoplankton
3. About 71 percent of the Earth's surface is water-covered, and the oceans hold about 96.5 percent of all Earth's water. Water also exists in the air as water vapor, in rivers and lakes, in icecaps and glaciers, in the ground as soil moisture and in aquifers, and even in you and your dog.
Explanation:
Did you know that more than half of the oxygen on earth is produced by these tiny one-celled plants in the surface of the ocean called phytoplankton?
hope this help
Surface event that takes place during the rock cycle is the weathering.
The weathering is process in the rock cycle that takes place only on the surface. It is a process that causes the breakdown of the rocks, be it slowly and gradually, or very quickly and dramatically.
The weathering can be in multiple ways, with the physical weathering being the dominant one.
This process is later supported by the erosion, as it is the process that takes away the material that the weathering managed to break off.
