As you move toward the center of the earth, temperature and pressure increase Layers of Earth Crust Continental Crust: thicker, less dense, older Oceanic Crust: thinner, more dense Mantle: thickest layer, hot rock, convection currents that move tectonic plates Core Outer Core: liquid, circulates around the inner core, iron & nickel Inner Core: solid, iron The circulation of the liquid outer core material around the inner core causes earth’s magnetic field Zones in Earth’s Layers Lithosphere: Earth’s crust & the rigid upper mantle Broken into tectonic plates Asthenosphere: soft, upper part of the mantle Magma Tectonic plates move on top of the asthenosphere
