How does water get from land to sea?
When rain falls on land it gets held up in the soil, wetlands, groundwater, lakes and reservoirs on its journey back to the oceans. This is collectively referred to as “land water storage”. This water has ended up in the oceans, adding 0.38mm per year to global sea levels over the past two decades.
What are the two ways water enters the ocean from the land?
Water from the land enters the oceans through seepage from the ground; it percolates from the surface down to the water table. This water-saturated zone of soil and rock is called an aquifer and water seeps from the aquifer to the ocean. Water also reaches the ocean as runoff from the surface.
What are the 7 main seas?
The Seven Seas include the Arctic, North Atlantic, South Atlantic, North Pacific, South Pacific, Indian, and Southern Oceans. The exact origin of the phrase ‘Seven Seas’ is uncertain, although there are references in ancient literature that date back thousands of years.
What are the ancient seven seas?
The ancient Romans called the lagoons separated from the open sea near Venice the septem maria or seven seas. Most current sources state that “seven seas” referred to the Indian Ocean, Black Sea, Caspian Sea, Adriatic Sea, Persian Gulf, Mediterranean Sea, and the Red Sea.
Which is the scariest ocean?
The Devil’s Sea is called the Bermuda Triangle of the Pacific, and it’s not difficult to understand why: this area off the coast of Tokyo is also known for strange disappearances and shipwrecks, including the MV Derbyshire, the biggest ship ever lost at sea. It was twice the size of the Titanic.
What happens if we drink sea water?
Seawater is toxic to humans because your body is unable to get rid of the salt that comes from seawater. Your body’s kidneys normally remove excess salt by producing urine, but the body needs freshwater to dilute the salt in your body for the kidneys to work properly.
How does most water return to the ocean?
Water evaporates from within soils and through vegetation and from bodies of water (such as rivers, lakes and oceans). This evaporated water accumulates as water vapour in clouds and returns to the Earth as rain or snow. The returning water falls directly back into the oceans, or onto land as snow or rain.
How does the water cycle affect the ocean?
Biological in the ocean is affected by the water cycle via the Mixed Layer Depth and Run off from land. Finally, feedback between Physical and Biological Oceanography include the sea-ice and haline enivironments. Evaporation (“E”) controls the loss of fresh water and precipitation (“P”) governs most of the gain of fresh water.
How does water temperature affect the ocean’s movement?
Because the molecules are more spread out, the density goes down. When water cools, it contracts and becomes denser. Temperature and salinity both affect the density of water, resulting in water moving up or down through the ocean layers and moving as currents around the ocean.
What way does the ocean water move globally?
Following the pull of gravity, ocean water moves from the built-up areas of high pressure down to the valleys of low pressure. But as the water moves from hills to valleys, it does so in a curved trajectory, not a straight line. This curving is a result of Earth’s spin on its axis.
