the surface of the earth

Earth is the third planet from the Sun and the only astronomical object known to harbor life.Chemically, Earth can be divided into the crust, upper Earth is the third planet from the Sun and the only astronomical object known to harbor life. About 29% of Earth's surface is land consisting of continents and islands. The remaining 71% is covered with water, mostly by oceans but also by lakes, rivers and other fresh water, which together constitute the hydrosphere. Much of Earth's polar regions are covered in ice. Earth's outer layer is divided into several rigid tectonic plates that migrate across the surface over many millions of years. Earth's Chemically, Earth can be divided into the crust, upper mantle, lower mantle, outer core, and inner core. The geologic component layers of Earth [not in citation given] are at the following depths below the surface Earth is the planet we live on. It is the third planet from the Sun. It is the only planet known to have life on it. The Earth formed around 4.5 billion years ago. It is one of four rocky planets on the inside of the Solar System. The other three are Mercury, Venus, and Mars. The large mass of the Sun makes Earth move around it, just as the mass of Earth makes the moon move around it. Earth also turns around in space, so that different parts face the Sun at different times. Earth goes around the Sun Earth Surface Processes considers the physical and chemical fluxes across the Earth’s surface, the processes that determine these fluxes, and the resulting landscapes. The Earth’s surface acts as a diffusive boundary that separates the atmosphere from the lithosphere, resulting in a global topography determined by the interaction of tectonic and climatic is estimated to have formed around 4.5 billion years ago – almost one-third of the age of the universe – through accretion from the solar nebula. Earth is the third planet from the Sun, at a distance of 1 AU or 147 million km / 91 million mi. It is the fifth-largest planet in the Solar System, being the largest of the terrestrial is covered with water, and the remaining 30% is taken up by the seven continental landmasses. However, underneath the water that fills the oceans, and the dirt and plants that cover the continents, the Earth's surface layer is made of rock. This outer layer formed a hard, rocky crust as lava at the surface cooled 4.5 billion years rotation causes the periods of light and darkness we call day and night. The part of the Earth facing the sun is in daylight; the part facing away from the sun is in darkness. If the Earth did not rotate, one-half of the Earth would always be too hot to support life, and the other half would be frozen. Earth rotates from west to east, so the sun appears to rise in the east and set in the might also be interested in: Science, Evolution, and Creationism. How did life evolve on Earth? The answer to this question can help us understand our past and prepare for our future. Although evolution provides credible and reliable answers, polls show that many people turn away from science, seeking other explanations with which they are more comfortable millions of years, the surface geology of the Earth changed dramatically because of this. Where the crust is weaker magma can push its way through thus erupting onto the surface, forming volcanoes. Because of volcanoes, material wells out creating new land, and they also pump out gas that greatly contributed to Earth’s atmosphere. The interior of the Earth is very hot – comparable to  earth surface system is a set of interconnected components of the earth surface environment that function together as a complex whole. Earth's surface modeling is generally defined as a spatially explicitly digital description of an earth surface system or a component of the earth surface environment
