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’s surface do humans cover?

Human beings take up a lot of real estate — around 50-70 percent of the Earth’s land surface. And our increasing footprint affects how mammals of all sizes, from all over the planet, move.

Are humans living on Earth or are humans part of Earth?

The presence of living organisms of any type defines the biosphere; life can be found in many parts of the geosphere, hydrosphere, and atmosphere. Humans are of course part of the biosphere, and human activities have important impacts on all of Earth’s systems.

How many acres is the land on the Earth?

The world relative to its human population is quite large. It is 123 billion acres in size, of which 37 billion acres are land.

What percentage of Earth’s total lifetime is habitable?

The latest model predicts a total habitable zone lifetime for Earth of 6.3 billion–7.8 billion years, suggesting that life on the planet is already about 70\% of the way through its run.

What percentage of the Earth’s surface is land and how much of it can man use?

Less than 30\% of the 510 million square kilometers of area on the Earth’s surface is covered by land. There are over 510 million square kilometers of area on the surface of Earth, but less than 30\% of this is covered by land. The rest is water, in the form of vast oceans.

What percentage of the Earth is inhabited by humans?

Humans comprise a very small share of life on Earth — 0.01\% of the total, and 2.5\% of animal biomass [animal biomass is shown in the right-hand box on the visualization above].

How deep in the earth do diamonds form?

Most form at depths above 200 kilometers (124 miles). But rare “super-deep” diamonds may have formed as far down as 700 kilometers (435 miles) below the surface. These crystals are then brought to the surface in volcanic rock known as kimberlite.

How far up does the atmosphere extend?

What do we know about the structure of the Earth?

Scientists understand much about Earth’s structural layers — the inner core, core, mantle and crust. Yet there are still great mysteries to solve about our planet’s inner workings. Mountain ranges tower to the sky. Oceans plummet to impossible depths. Earth’s surface is an amazing place to behold.

How fast does the Earth rotate per day?

The Earth rotates about its axis once a day, but it does not do so uniformly. Instead, the rate of rotation varies by up to a millisecond per day.
