What causes a shrinking ocean?
Seafloor spreading at midocean ridges produces and adds new area to the oceanic lithosphere. Thus, plate change size over time. Some grow, some shrink and even disappear if mostly oceanic. Oceanic lithosphere is lost by subduction at some plate margins.
How do oceans change the land?
The oceans influence climate by absorbing solar radiation and releasing heat needed to drive the atmospheric circulation, by releasing aerosols that influence cloud cover, by emitting most of the water that falls on land as rain, by absorbing carbon dioxide from the atmosphere and storing it for years to millions of …
How does the ocean expand?
Sea level continues to rise at a rate of about one-eighth of an inch per year. The two major causes of global sea level rise are thermal expansion caused by warming of the ocean (since water expands as it warms) and increased melting of land-based ice, such as glaciers and ice sheets.
Why is the ocean not flat?
Just as the surface of the Earth is not flat, the surface of the ocean is not flat. For instance, the absolute water level height is higher along the West Coast of the United States than the East Coast. The surface of the sea changes at different rates around the globe.

Which country will drown first?
Specifically, six Asian nations — China, Bangladesh, India, Vietnam, Indonesia, and Thailand — are predicted to be the most vulnerable. The peer-reviewed study states that 237 million people in these countries occupy areas that are highly likely to experience coastal flooding once or multiple times per year by 2050.
Will the world be underwater?
The simple answer is no. The whole world will never be underwater. But our coastlines would be very different. If all the ice covering Antarctica , Greenland, and in mountain glaciers around the world were to melt, sea level would rise about 70 meters (230 feet).
