Earth-Science

• Vibrations that travel through Earth carrying the energy released during an earthquake. -Seismic Waves
• The outer layer of earth - Crust
• a usually light-colored rock that is found in continental crust - Granite
• the solid, outer layer of the earth that consists of the crust and the rigid upper part of the mantle - Lithosphere
• the layer of hot, solid material between Earth's crust and core - Mantle
• a layer of molten iron and nickel that surrounds the inner core of Earth - Outer Core
• the direct transfer of heat from one substance to another substance that it is touching - Conduction
• the movement of a fluid, caused by differences in temperature, that transfers heat from one part of the fluid to another - Convection Current
• the hypothesis that states that the continents once formed a single landmass, broke up, and drifted to their present locations - Continental Drift
• large, ancient landmass that was composed of all the continents joined together - Pangea
• the process by which molten material adds new oceanic crust to the ocean floor - Sea Floor Spreading
• the theory that pieces of Earth's lithosphere are in constant motion, driven by convection currents in the mantle - Plate Tectonics
• the type of stress that occurs when an object is squeezed- Compression
