2. As the pot of soup boils, heat transfers from the hot soup to the spoon in the pot. • Radiation from the sun heats this planet. • I touched the car and the conduction caused me to feel the heat. • Convection causes the air in the room to be the same in all parts of the room. • There is a convection current in a pot of soup, as it boils. • Alfred Wegener was the man who claimed that continental drift explained many things.

3. The plate moved and slammed into another plate, creating a mountain. • Plate Techtonics is a theory that gives reason to why the plates move across the earth. • Sea-floor spreading became evident while scientists mapped the ocean floor, and was later viewed by scientist while viewing the seafloor with an ROV. • Subductionis the plate boundary where the earth is being recycled.

4. Heat Transfer: The movement of energy in the form of heat from a warmer object to a cooler object. • Radiation: The direct transfer of energy (heat) through empty space by electromagnetic waves. • Conduction: The transfer of heat from one substance to another by direct contact of particles of matter. • Convection: The transfer of heat by movement of a fluid. • Convection current: The movement of a fluid, caused by differences in temperature, the transfer of heat from one part of the fluid to another.

5. Continental ‘drift: the hypothesis that the continents slowly move across Earth’s surface. • Plate: A section of the lithosphere that slowly moves over the asthenosphere, carrying pieces of continental and oceanic crust. • Plate Techtonics: the theory that pieces of Earth’s lithosphere are in constant motion, driven by convection currents. • Sea-floor spreading: The process by which molten material adds new oceanic crust to the ocean floor. • Subduction: the process by which oceanic crust sinks beneath a deep-ocean trench and back into the mantle at a convergent plate boundary.
