The '''Earth''' is the third planet in the [[Solar System]]. It is the largest of the terrestrial planets<ref>"Terrestrial planets are planets made up of rocks or metals with a hard surface — making them different from other planets that lack a solid surface. Terrestrial planets also have a molten heavy metal core, few moons, and landforms such as cliffs, valleys, volcanoes and craters." [https://gml.noaa.gov/education/info_activities/pdfs/TBI_terrestrial_planets.pdf] Four such planets exist in our solar system: Mercury, Venus, Earth and Mars.</ref> and is the only known [[planet]] which has [[life]] as we know it. The surface of the planet is approximately two-thirds covered in [[water]]. The atmosphere is roughly 78% [[nitrogen]] and 21% [[oxygen]], with trace amounts of water vapor, [[carbon dioxide]], and other elements. The Earth is roughly 14.5 billion years old. ref>[https://www.letu.edu/academics/arts-and-sciences/files/age-of-earth.pdf  Steven Ball, Ph., "A Christian Physicist Examines the Age of the Earth”.]</ref> (See also: [[Age of the Earth]]).
