Earth's axis of rotation is tilted with respect to the perpendicular to its orbital plane around the Sun, producing seasons. Earth rotates around its own axis in slightly less than a day (in about 23 hours and 56 minutes).

Earth is about eight light-minutes away from the Sun and orbits it, taking a year (about 365.25 days) to complete one revolution. Of the four rocky planets, it is the largest and most massive. It is the densest planet in the Solar System. Differences in the amount of captured energy between geographic regions (as with the equatorial region receiving more sunlight than the polar regions) drive atmospheric and ocean currents, producing a global climate system with different climate regions, and a range of weather phenomena such as precipitation, allowing components such as nitrogen to cycle.Įarth is rounded into an ellipsoid with a circumference of about 40,000 km. This process maintains the current average surface temperature of 14.76 ☌, at which water is liquid under atmospheric pressure. The water vapor acts as a greenhouse gas and, together with other greenhouse gases in the atmosphere, particularly carbon dioxide (CO 2), creates the conditions for both liquid surface water and water vapor to persist via the capturing of energy from the Sun's light. Water vapor is widely present in the atmosphere, forming clouds that cover most of the planet. It has a composition of primarily nitrogen and oxygen. Earth has a liquid outer core that generates a magnetosphere capable of deflecting most of the destructive solar winds and cosmic radiation.Įarth has a dynamic atmosphere, which sustains Earth's surface conditions and protects it from most meteoroids and UV-light at entry. Earth's crust consists of slowly moving tectonic plates, which interact to produce mountain ranges, volcanoes, and earthquakes. Most of Earth's land is somewhat humid and covered by vegetation, while large sheets of ice at Earth's polar deserts retain more water than Earth's groundwater, lakes, rivers and atmospheric water combined. The remaining 29.2% of Earth's crust is land, most of which is located in the form of continental landmasses within one hemisphere, Earth's land hemisphere. Almost all of Earth's water is contained in its global ocean, covering 70.8% of Earth's crust.

This is enabled by Earth being a water world, the only one in the Solar System sustaining liquid surface water. ≤1% water vapor ( climate variable) Įarth is the third planet from the Sun and the only astronomical object known to harbor life.
