Admin Does the sea have an end?
While this question appears to have a simple answer, the reality is that all the world’s waterways are connected to each other. There are no borders within the water itself, rather the names were human constructs given to different oceans in regard to around which bodies of land they flow.
Where does the water in the sea come from?
Rocks on land are the major source of salts dissolved in seawater. Rainwater that falls on land is slightly acidic, so it erodes rocks. This releases ions that are carried away to streams and rivers that eventually feed into the ocean.
How deep can we go in the ocean?
The deepest point ever reached by man is 35,858 feet below the surface of the ocean, which happens to be as deep as water gets on earth. To go deeper, you’ll have to travel to the bottom of the Challenger Deep, a section of the Mariana Trench under the Pacific Ocean 200 miles southwest of Guam.
When did the oceans first form on Earth?
There are now two hypotheses for when oceans originated on Earth. Hypothesis 1: Oceans first formed at ca. 3800 Ma. The Isua BIF provides definitive ‘ground truth’ that surface water was indeed stable at 3800 Ma, however no ‘boundary condition’ can be defined by the Isua BIF.
What’s the difference between the sea and the ocean?
For other uses, see Sea (disambiguation) and The Sea (disambiguation). The sea, connected as the world ocean or simply the ocean, is the body of salty water that covers over 70 percent of the Earth ‘s surface. The word sea is also used to denote second-order sections of the sea, such as the Mediterranean Sea, as well as certain large,
How are seas formed and what makes them salty?
Seas are formed when river water flows into the huge amount of half dried land then when it starts to rain water fills it up and the minerals from the ground makes it salty. Wiki User ∙ 2014-09-25 17:29:15
How does the sea play a role in the water cycle?
Water cycle. The sea plays a part in the water or hydrological cycle, in which water evaporates from the ocean, travels through the atmosphere as vapour, condenses, falls as rain or snow, thereby sustaining life on land, and largely returns to the sea. Even in the Atacama Desert, where little rain ever falls,…
