How would the Earth be different if we had no oceans?

The oceans are gone, but we still have some water. (About 68.7 percent of Earth’s fresh water is frozen in glaciers, ice caps and permanent snow, mostly in Antarctica [source: USGS].) Without clouds forming over the ocean, rain would be incredibly rare, and the planet would become desert.

How would Earth’s climate be different if there were just oceans and not land?

Without currents in the ocean, regional temperatures would be more extreme—super hot at the equator and frigid toward the poles—and much less of Earth’s land would be habitable.

What would happen if all marine life vanished?

Without them, life as we know it will not be possible. The ocean will no longer be able to perform many of its essential functions, leading to a lower quality of life. People will starve as they lose one of their main food sources. The effects of a world without fish in the sea would be felt by everyone.

What happens if ocean life dies?

Paul Watson: The reality is that if the ocean dies, we die – because the ocean provides all of those things which make it possible for us to live on the planet. If phytoplankton disappear, we disappear also, we can’t live on this planet without phytoplankton.

What would happen if there was no life in the ocean?

How would the global climate be different if more of Earth was covered by land and water?

Earth’s temperature would rise drastically. Also, evaporation of water from the oceans and rivers helps in regulating the Earth’s temperature. If water and land switched places, the Earth’s temperature would rise very quickly and it would become hotter. Large parts of the land masses would become arid and dry.

What will happen if there is no land on earth?

Earth’s fauna would change. The swapping of land and water would have many effects on Earth’s lifeforms. The temperature would rise drastically, the amount of oxygen in the atmosphere would decrease, and the amount of carbon dioxide would increase. All of this would make living on the planet hard.
