The transfer of energy through space. Takes place with no direct contact between a heat source and an object. Sunlight is an example of this.
Heat transfer within a material or between materials that are touching. A spoon in a pot of hot soup heats up by this.
Heat transfer by the movement of currents in a fluid. Heated particles of the fluid begin to flow. This flow transfers from one part of the fluid to another. The soup in a pot is heated in this way.
The idea, that the continents were once joined in a single land mass and have since drifted apart.
The name of the single landmass that broke apart 200 million years ago and now made today's continents.
Any trace of an ancient organism that has been preserved in rock.
An undersea mountain chain where new ocean floor is produced. They curve like the seam of a baseball along the sea floor. Iceland is part of one of these ridges.
The process by which molten material adds new oceanic crust to the ocean floor. As a result the ocean floors move like a conveyor belt, carrying the continents along with them.
When the ocean floor plunges into deep underwater canyons and creates a valley beneath which oceanic crust slowly sinks toward the mantle.
The process by which ocean floor sinks beneath a deep-ocean trench and back into the mantle. It's like a dry wash cloth on the surface of the water that eventually gets heavy with water and sinks.
