A contour map, possibly.
It's about 25-30 percent land.
You cannot get the square footage of land which is measured in 5 dimensions. In fact I am not sure where you would find 5-dimensional land.
Land 261914 sq. mi.
None. A foot is a measure of length or distance in 1-dimensional space while a decimal is a measure of area in 2-dimensional space. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid without some addition information.
A contour map, possibly.
A globe provides a more accurate representation of Earth because it is a three-dimensional model that accurately depicts the spherical shape of the planet. Flat maps, on the other hand, distort the size and shapes of land masses when projecting the globe onto a two-dimensional surface.
A world contour map shows the elevation or depth of land and ocean floor features using contour lines. These lines connect points of similar elevation or depth to provide a visual representation of the terrain in a two-dimensional format. World contour maps help in understanding the topography and bathymetry of the Earth's surface.
There can be no answer. Square acre is a measure in 4-dimensional hyperspace. Land is not 4-dimensional and we cannot perceive 4-d space.
Maps distort land masses because it is impossible to accurately represent a three-dimensional object (Earth) on a two-dimensional surface (paper or screen). This distortion occurs because of the challenge in projecting a curved surface onto a flat plane, leading to inaccuracies in representing the true sizes and shapes of land masses. Different map projections are used to minimize distortion in specific areas, but some level of distortion will always be present in map representations.
Planimetric maps are useful for providing visual representation of physical features on a flat surface, facilitating navigation and spatial analysis. They are commonly used in urban planning, land surveying, architectural design, and infrastructure development. These maps depict two-dimensional features such as roads, buildings, rivers, and boundaries with accuracy for planning and decision-making purposes.
Mapmakers have to deal with the challenge of representing a three-dimensional object (Earth) on a two-dimensional surface (map). This leads to distortions in either land shapes or sizes, known as map projection distortion. Mapmakers have to prioritize either preserving shapes or accurately representing sizes when choosing a map projection.
About one third of the land surface of the earth is desert.
The term that refers to all the land surface of the earth is "Lithosphere."
Earth is three-dimensional, but maps are two-dimensional.
Land is above the waterline. No surface currents can flow over land.
About 33% of the earth's land surface is covered by deserts. That's 1/3 of the surface.
