Underwater Volcanoes Most volcanoes happen under the water, on the ocean floor. Each time these volcanoes erupt, they grow bigger. Some underwater volcanoes grow so tall that the top can be seen above the water. They form islands in the sea. In some places, a whole line of undersea volca...
Ocean, continuous body of salt water held in enormous basins on Earth’s surface. There is one ‘world ocean,’ but researchers often separate it into the Pacific, Atlantic, Indian, Southern, and Arctic oceans. Covering nearly 71 percent of Earth’s surf
There is a growing global water scarcity crisis, and yet we are surrounded by abundant water. Tragically, all that water is just out of reach. Some 97.5 percent of the Earth's water is salty, and most of the rest is freshwater that is spread out...

The world’s oceans are under threat from the prevalence of heatwaves caused by climate change. Despite this, there is a lack of understanding regarding their impact on seawater oxygen levels - a crucial element in sustaining biological survival. Here, we find that heatwaves can trigger low-oxy...
the sun and the rotation of the earth.The sun affects the ocean by heating the atmosphere, creating winds and moving the sea surface through friction.This tends to drag the water surface along as the wind blows over it.Secondly, it affects the ocean by altering the density of the ocean su...
