In the visualization we see the breakdown of global land area today. Are you a teacher? The amount of water located on Earth is enough to cover the entire land mass of the contiguous United States to a depth of 107 miles. By using such imaging satellites as Landsat 5, Landsat 7 and Terra, scientists have the ability to observe large tracts of the Earth's surface in a fraction of the time needed to complete aerial or ground surveys. 7 billion folks would take up about 14 billion square feet, which I think is about 500 square miles. Land cover classes can usually be discriminated by characteristic patterns using remote sensing. As you go West- those percentage probably go up quite a bit- Nebraska, Montana, Colorado, Utah, Idaho etc. The zealots included land which is being farmed and forested, but this land is not subject to any kind of contamination. 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. Why is it important to study rocks? naturally regenerated forests of native species, where there are no visible indications of human activities and the ecological processes are … Artificial surfaces include any areas that have an artificial cover as a result of human activities such as construction (cities, towns, transportation), extraction (open mines and quarries) or waste disposal. 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. This site uses Akismet to reduce spam. Dynamic land cover maps include transitions of land cover classes over time and hence captures land cover changes. The volume of aquifer water is about 5,614,000 cubic miles. Area of water: 361 740 000 km2 (139 668 500 square miles), this are 71% of the total surface of the Earth. However, even non-urban areas contain roads, train tracks, farms and other marks of human domination. Which biome is the smallest? Hills & mountains help the wet air to rise up in order to increase density of clouds, which ultimately rains. Puerto covers approximately 100 by 35 miles. Other lands are any lands not arable or under permanent crops; this includes permanent meadows and pastures, forests and woodlands, built-on areas, roads, barren land, etc. Already a member? forests, grasslands, croplands, lakes, wetlands. Question 1 What percentage of Earth's land surface do glaciers currently cover? These volumes are surprisingly close while saline oceanic water bears no comparison at all, with a volume of 321,000,000 cubic miles. Land covers 30% of the Earth, while the Oceans take up the remaining 70%. Most of you wouldn’t know true science if it was sitting next to you. 2. About 30%, then, of Earth's total freshwater is ground aquifer water or about one-third the amount frozen is icecaps and glaciers. The third greatest source of water, after (1) oceans and seas and (2) icecaps and glaciers, is ground water, or aquifers. Permanent pastures are 68.4% of all agricultural land (26.3% of global land area), arable land (row crops) is 28.4% of all agricultural land (10.9% of global land area), and permanent crops (e.g. Subtracting this uninhabitable 57% (32,665,981 mi 2 ) from the total land area leaves 24,642,757 square miles or 15.77 billion acres of habitable land. 95% of the world's population is concentrated on just 10% of the world's land; but only 10% of the world's land area is classified as "remote" or more than 48 hours from a large city. Seen from space, the majority of the Earth’s surface is covered by oceans – that makes up 71% of the surface of the Earth, with the remaining 29% … Curious Meerkat uses cookies. If we do or don’t do it, someone will laugh, Your email address will not be published. This figure gives us an estimate of roughly 900,000 km2 of human-covered land worldwide. Both cloud cover percentages are listed in the EarthExplorer metadata, as well as in the Landsat Collection 1 Level-1 metadata (MTL.txt) file. Because of the oceans' importance, more and more studies are revealing more and more interactions and connections. The maps are also critical for scientists as they study changes in the Earth system and as they model the Earth system. More than 68 percent of the planet's fresh water is largely inaccessible, located in glaciers, ice caps and permanent snow. Claire is a Freelance Science Writer and Communicator, and Innovation Officer for the London NERC Doctoral Training Partnership. Forest area (percentage of land area) 2007: 30.3 % of land area: Other land: 2007: 41 404 989: km 2: Other land per 1000 population : 2007: 6.0: km 2 per 1000 population: Other land (percentage of total area) 2007: 30.4 % of total area: Other land (percentage of land area) 2007: 31.8 % of land area Once you have a measure of the area you are interested in, and a measure of the area of Earth's entire surface, finding the percentage is basic sixth-grade arithmetic. Our summaries and analyses are written by experts, and your questions are answered by real teachers. km) Urban land area (sq. 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. The FAO GLC SHARE data shows that 12.6% of land is categorised as cropland. Approximately half the forest area is relatively intact, and more than one-third is primary forest (i.e. For years scientists across the world have been mapping changes in the landscape (forest to field, grassland to desert, ice to rock) to prevent future disasters, monitor natural resources, and collect information on the environment. Do the oceans cover 75 percent of the entire Earth? What are the differences between a crater and a caldera? But just how much water exists on, in, and above our planet? Seriously?
