GEOLOGY

Detailed explanation-1: -There are five main systems, or spheres, on Earth. The first system, the geosphere, consists of the interior and surface of Earth, both of which are made up of rocks. The limited part of the planet that can support living things comprises the second system; these regions are referred to as the biosphere.

Detailed explanation-2: -The geosphere is the collective name for the earth’s atmosphere, lithosphere, hydrosphere, and cryosphere.

Detailed explanation-3: -The Earth’s geosphere is divided into three chemical sections: The crust, composed almost entirely of light elements, like silicon. The mantle, which is 68% of the Earth’s mass. The core, the innermost layer; it is composed of very dense elements, such as nickel and iron.

Detailed explanation-4: -The lithosphere, sometimes called the geosphere, refers to all of the rocks of the earth. It includes the planet’s mantle and crust, the two outermost layers.
