The ocean waters at the equator are warm because they receive more of the sun rays than the waters at the at the poles. Therefore, the water in these regions is less dense than those at the poles. The oceans currents, moving towards the poles from the equator, move on the surface waters while those from the poles move on the ocean floor.
As the warm currents move to the poles and cool, they become more saline because they become more concentrated with salts –saturation point lowers with temperatures. At the poles, most of the salts in ejected from the waters as brine as the water sinks to the ocean floor due to density.
This movement of water currents in such circular motion forms the Thermohaline Circulation. Heat on the planet is distributed in this way.
Answer:
Hiya there!
Explanation:
The difference between plant cells and animal cells is that plant cells are surrounded by a cell wall wile animal cells are not. The existence of the cell wall is used for photosynthesis of plants because it is in the cell wall where the chloroplast is located. Plant cells do not have lysosomes which has an important function for waste disposal of animal cell.
