One third of the earth's surface is desert.

We're changing the characteristics of the surface of the land, the reflectivity.

Three fourths of the earth's surface is water.

Think of the surface of a sphere just like a beach ball, the surface of the Earth.

About three fourths of the earth's surface consists of water.

Let's first look at the relationship of ultraviolet radiation to the Earth's surface.

Dry areas cover more than one third of the Earth's land surfaces.

Three fourths of the earth's surface is covered with water.

The TOMS 7 satellite data, shown here, show the annual average ultraviolet radiation at the Earth's surface.

In physiology and medicine, the body surface area (BSA) is the measured or calculated surface area of a human body.

At approximately 14,000 km², it covers approximately one fifth of the area of the forest.

Since most of the air is located closest to Earth s surface, the troposphere is the densest layer of the atmosphere.

It accounts for 20 percent of the land area and 60 percent of the population ( 2007 census ) of the entire province of Cebu.

And he showed that gasses such as CO2 absorb heat, thus acting like a blanket warming Earth's surface.

Nowadays, Schiphol Airport is the major civilian aviation hub in the Netherlands, using 15 of Haarlemmermeer's land area.

Terrestrial

And there are a few other land dwellers that can make light some insects, earthworms, fungi but in general, on land, it's really rare.

But if you were to put it on an equal area projection, you'd see that the mid ocean ridge covers 23 percent of the Earth's total surface area.

Astronomers use flux to denote the apparent brightness of a celestial body. The apparent brightness is defined as the amount of light received from a star above the earth atmosphere passing through a unit area each second. Therefore, the apparent brightness is simply the flux we receive from a star.

All across most land masses.

This magma being less dense, rises to the surface and goes through the weak parts of the Earth's crust (the faults) resulting in volcanic processes in the area.

After centuries of unsustainable use, as well as rapidly escalating forest destruction since 1950, less than 60,000 km2 (23,000 sq mi) or 10 of Madagascar's land area remains forested.

No to the Egyptian land incursion in Yemen.

It seems that the ground offensive is imminent!

(iii) Solar terrestrial physics

Moreover, while some 13 of the world s land area is currently protected, only 14 of the 17 that contains the most plant species fall within the protected areas.

Most are terrestrial, though all are capable of climbing.

But a land incursion will mean death for Egyptian soldiers.

If you take the 10 countries that went on to become the Western empires, in 1500 they were really quite tiny five percent of the world's land surface, 16 percent of its population, maybe 20 percent of its income.

The saddle shaped structure is also known as a hyperbolic paraboloid surface, or an anticlastic surface.

So, I look to you, fellow member of the Earth community.

The surface of the moon is irregular.

On the back there is scales and measurements for terrestrial navigation.

Surface

What is the acreage of your ranch?

So it's to look beyond the surface.

We need to see beyond the surface.

And TV, satellite and cable revenues are way up.

The surface of the earth is 70 water.
