If all land were oceans and all oceans were land, Earth would be a really completely different place. The temperature would rise, the local weather would change into erratic, the composition of the ambiance would change, and life would change into harder.

The Earth’s floor consists of roughly 71 p.c water and 29 p.c land, and the oceans maintain virtually 97 p.c of all water assets on the planet.
If this ratio were reversed, Earth would be drastically completely different if a strong landmass made up a lot of the Earth’s floor.
If life were attainable, the variations would be fairly massive, as Earth helps a wholly completely different type of life.
After placing the thought of ”if all land were oceans and all oceans land” firmly in our minds, let’s examine what it would take to reside on such a planet.
1. World temperature could rise
As a result of water has a excessive particular warmth capability, the oceans are reasonably heat, which implies that in contrast to land, it absorbs extra warmth with out a vital improve in temperature.
With out such massive reservoirs of water, Earth’s temperature rise would be removed from gradual.
One other factor that may happen is a lowered absorption of greenhouse gases by the oceans. Which means that oceans, that are pure sinks of carbon dioxide, can’t take in all the additional greenhouse gases, thus resulting in a extremely saturated ambiance.
World warming will speed up and Earth’s temperature will rise, just like Venus, the place world warming is plentiful.
2. Irregular climates
If the oceans are transformed to land, the water cycle will likely be disrupted and precipitation over land areas will likely be considerably lowered. This can result in droughts and a excessive variance in continental local weather.
Land areas nearer to the oceans will likely be reasonably liveable, whereas land areas within the center away from the oceans will likely be a highly regarded desert.
The excessive altitude areas will step by step rework into rainforests, whereas the excessive distance to the oceans will result in day by day local weather fluctuations within the continental areas.
With the capability of the oceans diminishing, the currents would lose their impact, inflicting the temperature gradient throughout land plenty to be terribly excessive.
3. Ambiance composition
About 50-70 p.c of the oxygen within the air is supplied by aquatic vegetation. If the oceans took up much less house, oxygen would not be replenished as shortly as it’s utilized by land organisms.
In consequence, the quantity of oxygen will lower, whereas the quantity of carbon dioxide will improve. Far more air and soil air pollution would be noticed.
Additionally, industries and different factories that use our bodies of water as sinks to empty their waste will face main issues.
It also needs to be famous that with the drastically altering composition of the air, the kinds of organisms that thrive in such situations will adapt to excessive temperatures and poisonous air in very alternative ways.
4. Life results
Life would come to land a lot earlier by way of the evolutionary cycle as a result of there would be much less space of ocean to behave as a habitat.
Because the oceans can’t meet their vitality wants, extra organisms will transfer to land.
To deal with the water scarcity, animals would even be comparatively smaller in dimension, whereas the variety of carnivores would improve as a result of discount of bushes and vegetation on land.
Even if they might survive excessive temperatures, the anatomy of people would be very completely different. People would in all probability not be as dependent on water as we do now and would develop higher technique of locomotion on land, corresponding to extra agile limbs and even wings.
As a result of day and night time temperatures would range drastically, not one of the extra advanced animals corresponding to birds and mammals would survive. A chilly-blooded inhabitants would rule the Earth.
5. It would be more durable to outlive
The mass of the Earth might additionally improve barely on account of extra land. However this small change can have ripple results in species varieties and the general ecosystem.
The oceans are an essential supply of thermal and electrical vitality, and their vitality calls for can now not be met as a result of dramatic discount of their dimension.
The oceans act as stabilizing entities that management the motion of land plenty. With out them, the continents would change into unstable and devastated by additional volcanic eruptions, earthquakes, and tectonic shifts.
6. Economic system and civilization
The absence of pure obstacles corresponding to oceans will lead to a single massive land mass. Since a unified authorities can’t govern such a big space, this huge piece of land will possible result in extra nations and extra battle.
Civilizations have traditionally developed close to water sources on account of commerce and simple accessibility, so conflicts are virtually sure to interrupt out on account of water shortage.
The plus facet would be the convenience of connectivity between areas by way of land and air journey. Nonetheless, delivery would be the sector most affected, as there would be restricted use for water transport.
Nations that depended on seafood and seafood would go bankrupt. As a result of life close to the oceans would be so scarce, folks dwelling there would lose their important meals supply and possible starve.
Even in continental areas, agriculture relies upon on plentiful water. If correct water calls for usually are not met, the extinction of the human race is very possible.
