Structure Of The Earth Internet Geography The structure of the earth. the crust and the upper mantle form the lithosphere. the lithosphere is around 100km thick and is solid and brittle. the lithosphere is divided into large sections called tectonic plates. tectonic plates consist of sections of the lithosphere. the oceanic lithosphere is topped by oceanic crust, and the continental. Composition: oceanic crust made up of iron, oxygen, silicon, magnesium and aluminium. continental crust made up of granite, sedimentary rocks and metamorphic rocks. the earth’s surface is covered by its thinnest layer, the crust. land is made of continental crust, which is 8km to 70km thick and made mostly from a rock called granite.
Structure Of The Earth Internet Geography 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. movement in the mantle caused by variations in heat from the core, cause the plates to shift, which can cause earthquakes and volcanic eruptions. these natural hazards. Figure 10h 1: layers beneath the earth's surface. the core is a layer rich in iron and nickel that is composed of two layers: the inner and outer cores. the inner core is theorized to be solid with a density of about 13 grams per cubic centimeter and a radius of about 1220 kilometers. the outer core is liquid and has a density of about 11 grams. The structure of the earth. the earth is made up of four distinct layers: the inner core is in the centre and is the hottest part of the earth. it is solid and made up of iron and nickel with temperatures of up to 5500°c. with its immense heat energy, the inner core is like the engine room of the earth. the outer core is the layer surrounding. Core, mantle, and crust are divisions based on composition. the crust makes up less than 1 percent of earth by mass, consisting of oceanic crust and continental crust is often more felsic rock. the mantle is hot and represents about 68 percent of earth’s mass. finally, the core is mostly iron metal. the core makes up about 31% of the earth.

Educational map game to learn the 5 layers of the earth. free resource for teachers. great tool for interactive whiteboard, computer, tablet and mobile. Image: nasa jpl, public domain. the core is the central region of the earth. it is 3475 km in radius. by volume, it is 16% of the earth body . by mass, it constitutes 32% of the mass of the earth. the temperature of the inner core is 60000 c – 70000 c. the inner core is composed of nife (ni for nickel fe for iron.).
