The less dense magma rises due to buoyancy and erupts at the earth’s surface (2) global tectonic theory: states that the earth’s surface consists of several rigid plates created at: mid-ocean ridges, destroyed at subduction zones, slide past eachother on transform faults. (5-7) Three major parts of earth: crust: contains mostly silicate minerals, rigid. Mantle made of silicate minerals, upper rigid, lower plastic. Core, contains metallic iron and nickel, outer core is molten inner is solid (3) Lithosphere-plates made up of crust and rigid upper mantle
