What will happen to the earth if the ocean suddenly disappears?

The ocean absorbs and digests solar radiation. If there is no water, strong sunlight will scorch the equator, and its energy cannot be dispersed to two levels, especially in winter. Fortunately, for us, water absorbs energy very well, so the ocean can adjust the global temperature. Ocean currents bring warm tropical seawater to the north and south poles, and cold water to the equator, which not only disperses heat energy, but also warms cold places.

When water is heated at the equator, it will evaporate into clouds. When warm air rises, it also absorbs lower temperature air from below. This process promotes the diffusion of heat and makes some places that are too cold to survive flourish and become lush gardens. That's why the Mediterranean is so warm, and why you can grow palm trees in Scotland, which is warm by the Gulf Stream.

If the ocean suddenly disappears, the earth's climate and temperature difference will change dramatically, and most of the creatures in the ocean will face extinction. The seabed is mostly composed of sediments, just like the beach by the sea. If seawater is desalinated, sediments will be exposed quickly.

Why do you say that most of the earth will become a desert instead of all? That's because besides the ocean, there are glaciers and groundwater. With the disappearance of the ocean, the temperature difference of the earth will increase rapidly, so high temperature will aggravate the melting of glaciers and Antarctic ice sheets and provide some water for life on earth. When this part of water is exhausted, the earth will gradually become a desert. Of course, this change has a certain process, not a rapid evolution.

If the sea really disappears, the former underwater world will also appear. We can see clearly whether it is a shipwreck or a plane crash in the triangle, but once there is no seawater, it means that the asthenosphere on the seabed surface will lose the weight of seawater. We also know that there are a large number of volcanoes on the seabed, and it is inevitable that these volcanoes will eject magma instantly. After all, the underwater world accounts for 7 1% of the world, which means that volcanic eruptions may occur in 7 1% of the earth. If volcanoes erupt in most parts of the world, then we humans may not be as simple as altitude sickness. Our breathing will become more difficult.
