What would happen if the earth were covered with over 70\% land instead of water?
The Temperature of the Earth Would Increase If most of the surface was land, however, then the land would be extremely hot, turning most of it into deserts, while the ice caps would grow smaller, flooding all the nearby land. Without such huge water reservoirs, the temperature rise of Earth would be far from gradual.
What would happen if the Earth was 90\% water?
If the entire world were covered with water, then the only source of freshwater would be rain and other forms of precipitation (e.g., snow, hail, etc.). If the world were covered with water, many of the ecosystems near land would also probably suffer, such as coral reefs, kelp forests, mangroves, and salt marshes.
What was the 70\% of the Earth’s surface is covered?
water
70\% of the earth’s surface is covered with water—with 97\% saltwater and 3\% freshwater.
What if the world had less water?
With no water supply, all vegetation would soon die out and the world would resemble a brownish dot, rather than a green and blue one. Clouds would cease to formulate and precipitation would stop as a necessary consequence, meaning that the weather would be dictated almost entirely by wind patterns.
What is 70 percent of Earth freshwater?
About 71\% of the Earth is covered in water. Most of that is in oceans, rivers, and lakes, but some is frozen in the Earth’s two ice sheets. Those ice sheets, which cover most of Greenland and Antarctica, only contain 2\% of the world’s total water supply, but a whopping 70\% of the Earth’s fresh water.
What covers 75 of Earth’s surface?
Viewed from space, one of the most striking features of our home planet is the water, in both liquid and frozen forms, that covers approximately 75\% of the Earth’s surface.
Why has 70\% of the earth covered with water?
Nature has covered 70\% of the earth with water simply because nature understood the importance of water for life on earth but nature had to store water some where so it made oceans/seas and system of rivers which flow from mountains into the ocean through the plains.
How much of the rain falls down into the ocean?
And the amount of this water is limited, generally to waporization from ocean surface and following rain. And as there is 70\% covered with water, again about 70\% of rain falls down into the ocean. There are already regions on Earth where there is not enough water for people, their cattle and plants.
What would happen if the earth’s surface was made up of land?
If most of the surface was land, however, then the land would be extremely hot, turning most of it into deserts, while the ice caps would grow smaller, flooding all the nearby land.
How would the Earth be different if it were closer to the ocean?
Land areas closer to the oceans would be moderately habitable, whereas the land in the middle, father away from the oceans, would be a very hot desert. The high altitude regions would gradually convert into rain forests, while the high distance from oceans would lead to daily fluctuations of climate in continental areas.
