| File info: Matter is a general term used to describe anything that has mass and occupies space. It includes everything around us, from solid objects like rocks and buildings to liquids like water and gases like air. Matter is composed of atoms, which are the basic building blocks of all matter. Now, when we refer to the Earth, we are specifically talking about our planet—the third planet from the Sun in our solar system. The Earth is a complex system that supports life and is made up of various materials and components. The Earth's structure can be divided into several layers. The outermost layer is the Earth's crust, which is made up of solid rocks and minerals. Beneath the crust is the mantle, a semi-solid layer primarily composed of silicate minerals. The core is at the center of the Earth and consists of a solid inner core and a liquid outer core, mainly made up of iron and nickel. The Earth is also characterized by its atmosphere, which is a layer of gases surrounding the planet. The atmosphere plays a crucial role in regulating temperature, protecting against harmful solar radiation, and supporting life. It's worth noting that matter is not exclusive to Earth. Matter exists throughout the universe in various forms, from stars and galaxies to interstellar dust and gas clouds. However, when we discuss matter in the context of Earth, we're referring to the substances and materials that make up our planet and its various components. | ||
