Why are seas shrinking?

The Aral Sea began to quickly shrink because of the evaporation of its now unreplenished waters. By 1989 the Aral Sea had receded to form two separate parts, the "Greater Sea" in the south and the "Lesser Sea" in the north, each of which had a salinity almost triple that of the sea in the 1950s.

Then, where is the dead sea?

Where is the Dead Sea located? The Dead Sea is a landlocked salt lake between Israel and Jordan in southwestern Asia. Accordingly, can we survive without the ocean? Without healthy oceans, our life on Earth would be severely challenged, unpleasant and perhaps impossible. The oceans are the life support system of all living beings. That's because life on Earth can thrive without land, but it cannot exist without an ocean.

Also, can the ocean be still?

The ocean is never still. Whether observing from the beach or a boat, we expect to see waves on the horizon. Waves are created by energy passing through water, causing it to move in a circular motion. And another question, how much of the ocean is empty? The ocean is an interesting place. As of the turn of the century (nearly 20 years ago now, but not much has changed), the National Oceanic and Atmospheric Administration (NOAA) estimated that as much as 95 percent of the ocean and 99 percent of the ocean floor remain unexplored.

Then, how long did it take for the aral sea to dry up?

In 2000 (left), Asia's Aral Sea had already shrunk to a fraction of its 1960 extent (black line). Further irrigation and dry conditions in 2014 (right) caused the sea's eastern lobe to completely dry up for the first time in 600 years. What were the impacts of the Aral Sea drying up? The shrinking Aral Sea has also had a noticeable affect on the region's climate. The growing season there is now shorter, causing many farmers to switch from cotton to rice, which demands even more diverted water. A secondary effect of the reduction in the Aral Sea's overall size is the rapid exposure of the lake bed.
