The development of agriculture, and then civilization, led to humans having an influence on Earth and the nature and quantity of other life forms that continues to this day. Beyond these, the exosphere thins out into the magnetosphere, where the geomagnetic fields interact with the solar wind. [177][178] The tiny near-Earth asteroid 2006 RH120 makes close approaches to the Earth–Moon system roughly every twenty years. The remaining 71% is covered with water, mostly by oceans but also lakes, rivers and other fresh water, which together constitute the hydrosphere. Earth is special because it is an ocean planet. About 74% of the surface of Earth is covered by liquid or frozen water. [61] The incorporation of smaller cells within larger ones resulted in the development of complex cells called eukaryotes.

Ranging from the equator to the polar regions, these are the tropical (or equatorial), subtropical, temperate and polar climates. Within the first billion years of Earth's history, life appeared in the oceans and began to affect Earth's atmosphere and surface, leading to the proliferation of anaerobic and, later, aerobic organisms. About 29% of Earth's surface is land consisting of continents and islands. The water is 3% fresh and 97% salted. However, you need to apply proper grammar rules in any sentence. This lower-density air then rises and is replaced by cooler, higher-density air. In astronomy, this is 1 AU – or an astronomical unit.

More precisely, the geoid is the surface of gravitational equipotential at mean sea level. [83] Even if the Sun were stable, a fraction of the water in the modern oceans will descend to the mantle, due to reduced steam venting from mid-ocean ridges.

Beneath the lithosphere is the asthenosphere, a relatively low-viscosity layer on which the lithosphere rides. [170], The Moon may have dramatically affected the development of life by moderating the planet's climate. [102] The thickness of the crust varies from about 6 kilometres (3.7 mi) under the oceans to 30–50 km (19–31 mi) for the continents. In winter, the climate becomes cooler and the days shorter. Photosynthesis provided a source of free oxygen, but the loss of reducing agents such as hydrogen is thought to have been a necessary precondition for the widespread accumulation of oxygen in the atmosphere.
