Our home planet is the third planet from the Sun, and the only place we know of so far that’s inhabited by living things.While Earth is only the fifth largest planet in the solar system, it is the only world in our solar system with liquid water on the surface. Just slightly larger than nearby Venus, Earth is the biggest of the four planets closest to the Sun, all of which are made of rock and metal
Planet Earth is dynamic with a surface that is always changing. Rocks can be converted into another type of rock, for example igneous to metamorphic. Several information describes the ways in which rocks are slowly recycled over millions of years and transformed between the three rock types: sedimentary, igneous and metamorphic rocks.
The structure of the earth is divided into four major components: the crust, the mantle, the outer core, and the inner core. Each layer has a unique chemical composition, physical state, and can impact life on Earth's surface.
