What percentage of the Earth's land is above the equator? There is an unequal distribution of land and water between the two hemispheres. The Southern Hemisphere has less land and more water. The Northern hemisphere is about 60.7% water and 39.3% land. The Southern hemisphere is about 80.9% water and 19.1% land. 63.7% of Earth's land mass is above the Equator.

- 1 The surface area of Earth is (pi x Diameter) = 197.38 million square miles (where pi = 3.14159265358979). 2  However, the Earth only has 57 million square miles of land (that's 36.48 billion acres; there are 640 acres per square mile). 3  However, there are only 12 million square miles (7.68 billion acres) of arable land.he world population in year 1 A.D. was 250 million people. The world population in year 1492 was 500 million people. The world population in 1804 was 1.0 billion people. The world population in 1922 was 2.0 billion people (doubled in 118 years; increasing on average by about 23,000 per day).

Area of Earth's Land Surface The land around the middle latitudes usually have hot summers and cold winters. The percentages of earth's land surface can be divided into different types: 20% covered by snow land, 20% mountains, 20% dry land, 30% good land that can be farmed, 10% land doesn't have topsoil. In my research all of the data found on the land surface area was around 1.5 × 108 km2. Daniel Chen -- 2001.

- by Jerry Coffey on February 18, 2009. The surface area of the Earth is 510 million square kilometers or 5.1×10 8 km 2. The Earth is a water heavy planet, so, if you break its surface area into water and land segments, it would look like this: land 149 million km 2, water 361 million km 2.

How Much of the Earth's Land Is Farmable? That's a lot of land, but much of it is not even remotely arable, as 20 percent of Earth's land mass consists of desert, and even more is devoted to alpine and arctic tundra, neither of which permits crop growth.

Geography of the Earth's Equator Since the Earth is an oblate spheroid an ellipsoid, it is slightly squished at the poles and bulges at the Equator as a result of gravity and its rotation. Thus, its diameter at the Equator is 26.5 miles (42.7 km) larger the polar diameter of 7,899.80 miles (12,713.5 km). Like its diameter, the Earth's circumference is also slightly larger at the Equator because of the equatorial bulge.

Definitions &Translations The Equator usually refers to an imaginary line on the Earth's surface equidistant from the North Pole and South Pole, dividing the Earth into the Northern Hemisphere and Southern Hemisphere. The Equator is about 40,075 kilometres (24,901 mi) long; some 78.7% lies across water and 21.3% over land.

Demographics of the world The world's population is 7 billion and Earth's total area (including land and water) is 510 million square kilometers (197 million square miles). Therefore, the worldwide human population density is 7 billion ÷ 510 million = 13.7 per km² (35.5 per sq. mile).

What Percent of Earth is Water? But how much of Earth is water – i.e. how much water contributes to the actual mass of the planet? This includes not just the surface of the Earth, but inside as well. In terms of volume, all of the water on Earth works out to about 1.386 billion cubic kilometers (km³) or 332.5 million cubic miles (mi³) of space. But in terms of mas, scientists calculate that the oceans on Earth weight about 1.35 x 10 18 metric tonnes (1.488 x 10 18 US tons), which is the equivalent of 1.35 billion trillion kg, or 2976 trillion trillion pounds.

What percent of Earth is water? But how much of Earth is water — how much water contributes to the actual mass of the planet? This includes not just the surface of the Earth, but inside as well. Scientists calculate that the total mass of the oceans on Earth is 1.35 x 10 18 metric tonnes, which is 1/4400 the total mass of the Earth. In other words, while the oceans cover 71% of the Earth’s surface, they only account for 0.02% of our planet’s total mass.

- Oceans cover about 70 percent of the Earth's surface and about 97 percent of all water on and in the Earth is saline—there's a lot of salty water on our planet. By some estimates, if the salt in the ocean could be removed and spread evenly over the Earth’s land surface it would form a layer more than 500 feet (166 meters) thick, about the height of a 40-story office building (NOAA).

How Much of the Earth's Land Is Farmable? Total Landmass of Earth. Earth is a watery place, with around 70 percent of its surface covered in water, the vast majority of which is salt water. This leaves around 30 percent of the planet's surface as potential farmland, totaling just over 57 million square miles.

Where the world lives: Map shows half the planet's population lives on just 1% of its land Where the world lives: Map shows half the planet's population lives on just 1% of its land. Land covers 196.9 million square miles of the planet, which is broken up into 196 countries that are home to 7.125 billion people. With so much land available on Earth you would think people are spread out evenly throughout the world - but a stunning new map reveals that isn't the case.

Equator The Web's Best Sites. The imaginary east-west line encircling the Earth midway between the North and South poles is called the equator. The circumference, or distance around, the equator is about 24,900 miles (40,000 kilometers). The equator divides the Earth into the Northern and Southern hemispheres. The latitude of the equator is defined as zero degrees. Latitude is a system of imaginary east-west. Equator...

The longer, equatorial axis of Earth's ellipsoid is more than 21.4 km (or 1/3 of 1 percent) longer than the polar axis. The flattening of the ellipsoid shown on this map was intentionally exaggerated.

Antarctic ice sheet Antarctic ice sheet. The Antarctic ice sheet is the largest single mass of ice on Earth. It covers an area of almost 14 million square km and contains 30 million cubic km of ice. Around 90 percent of the fresh water on the Earth's surface is held in the ice sheet, an amount equivalent to 70 m of water in the world's oceans. In East Antarctica, the ice sheet rests on a major land mass, but in West Antarctica the bed can extend to more than 2500m below sea level.

- In geography, the equator is an imaginary line drawn around a planet, halfway between the poles, where the surface of the roughly spherical planet is parallel to the axis of rotation. The equator divides the surface into the Northern hemisphere and the Southern hemisphere. The latitude of the equator is 0 by definition.
