How many square miles is habitable land on Earth?
24,642,757 square miles
The total land surface area of Earth is about 57,308,738 square miles, of which about 33\% is desert and about 24\% is mountainous. Subtracting this uninhabitable 57\% (32,665,981 mi2) from the total land area leaves 24,642,757 square miles or 15.77 billion acres of habitable land.
How much of the earth is covered by land mass?

How many square meters of land is there on Earth?
The Earth has a land area of 148,940,000,000,000.00000000000000000000 square meters. Only an estimated one-eighth of this area — or 18,618,000,000,000 square meters — is inhabitable by humans, with uninhabitable terrain such as deserts and high mountains covering the rest.

Who made Earth?
Formation. When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun. Like its fellow terrestrial planets, Earth has a central core, a rocky mantle, and a solid crust.
How is Earth’s area calculated?
Area of a Sphere To find the surface area of the Earth we have to use the formula of 4*Pi*radius squared. The radius of the Earth is approximately 6,371 kilometers.

How far is 3 million miles from Earth?
NASA’s OSIRIS-REx spacecraft took this incredible image of home from 3 million miles (5 million kilometers) from Earth, about 13 times the distance between the Earth and Moon. Asteroid Bennu, a carbon-rich hunk of rock that might contain organic materials or molecular precursors to life.
Can you dig to China?
You can technically dig through the Earth to get to China, but it’s more challenging than it sounds. To dig to China, you’d need to start your journey from Chile or Argentina — the location of China’s antipode (or opposite point on Earth).

How much of earth’s land is protected?
Despite this, only 20\% of land on the planet has been visibly impacted by human activity, and only 15\% of Earth’s land surface is formally under protection. The remaining 80\% of the land hosts natural ecosystems that help to purify air and water, recycle nutrients, enhance soil fertility, pollinate plants, and break down waste products.
How much habitable land is there on Earth?
How Much Habitable Land Is There On Earth? About 71\% of the total land surface on earth is habitable, with the rest being glaciers (10\%) and barren land (19\%). The quantities that make up those \%’s are: Habitable Land – 104 million km², or 64.6 million mi.². Glaciers – 15 million km², or 9.32 million mi.²
How much of the earth’s surface is land?
\% of Earth’s Total Surface That Is Land Most of the Earth’s surface is water (both saltwater, and fresh water bodies) Only about 29\% of the total surface of the Earth is land (such as continents and islands) Types Of Land, & Land Uses
How many landmasses are there in the world?
Earths Landmasses There are only four major landmasses on Earth. A continent is a landmass that measures millions of square kilometers and rises a considerable distance above sea level. Each continent has at least one large area of very old rock exposed at its surface called the shield. Shields form the cores of the continents.
