Earth is the third planet from the Sun and the only astronomical object known to harbor life. This is enabled by Earth being a water world, the only one in the Solar System sustaining liquid surface water. Almost all of Earth's water is contained in its global ocean, covering 70.8% of Earth's crust.
Environmental art is a range of artistic practices encompassing both historical approaches to nature in art and more recent ecological and politically motivated types of works. [1] [2] Environmental art has evolved away from formal concerns, for example monumental earthworks using earth as a sculptural material, towards a deeper relationship to ...
t. e. In geodesy, the figure of the Earth is the size and shape used to model planet Earth. The kind of figure depends on application, including the precision needed for the model. A spherical Earth is a well-known historical approximation that is satisfactory for geography, astronomy and many other purposes.
Land art, variously known as Earth art, environmental art, and Earthworks, is an art movement that emerged in the 1960s and 1970s, [1] largely associated with Great Britain and the United States [2] [3] [4] but that also includes examples from many countries.

The internal structure of Earth is the layers of the Earth, excluding its atmosphere and hydrosphere. The structure consists of an outer silicate solid crust, a highly viscous asthenosphere and solid mantle, a liquid outer core whose flow generates the Earth's magnetic field, and a solid inner core . Scientific understanding of the internal ...
Geocentric model. In astronomy, the geocentric model (also known as geocentrism, often exemplified specifically by the Ptolemaic system) is a superseded description of the Universe with Earth at the center. Under most geocentric models, the Sun, Moon, stars, and planets all orbit Earth.
