Fault | A huge crack in the Earth's crust at or below the surface, the sides of which may show evidence of motions. |
Focus | The point where an earthquake starts as rock begins to slide past each other. |
Seismic Wave | A vibration that spreads out away from a focus when an earthquake happens. |
Epicenter | The point on Earth's surface directly above the focus of an earthquake. |
Aftershock | Shaking of the Earth's crust after the initial shaking of an earthquake. |
Seismograph | A sensitive device that detects the shaking of Earth's crust during an earthquake. |
Magnitude | The amount of energy released by an earthquake. |
Vent | A central opening in a volcanic area through which magma may escape. |
Lava | Magma that reaches the Earth's surface and flows out of a vent. |
Crater | A cup-like hollow that forms at the top of a volcano around the vent. |
Hot Spot | A very hot part of the Earth's mantle, where magma can melt through a plate moving above it. |
Cinder-Cone Volcano | A steep-sided cone that forms from explosive eruptions of hot rocks, ranging from particles to boulders. |
Shield Volcano | A wide, gently sloped cone, that forms from flows of lava. |
Composite Volcano | A cone that forms from explosive eruptions of hot rocks followed by a flow of lava. |
Geothermal Energy | Heat from below the Earth's surface. |
Freezing | Changing from a liquid to a solid. |
Evaporation | Changing liquid to gas. |
Energy | The ability to move matter. |
Kinetic Energy | Energy in a moving object. |
Potential Energy | Energy stored in a object. |
Temperature | Average kinetic energy of molecules which tells us how hot or cold something is. |
Heat | A form of energy that flows between two objects that have different temperatures. |
Radiation | Transfer of energy by electromagnetic waves. |
Conduction | Movement of energy through direct contact. |
Convection | Transfer of energy by flow of a liquid or gas. |
Insulation | Preventing heat from flowing in or out of a material. |
Thermal Expansion | Matter expands when the temperature is raised. |
Pressure | The force on each unit of area of a surface. |
Melting | Changing a solid to a liquid. |
Condensation | Changing from a gas to liquid. |
Forms of Energy | Solar, wind, geothermal, nuclear, and hydroelectric. |
Solar Cell | Captures sunlight to make energy. |
Hydroelectricity | Energy from falling water. |
Nuclear Energy | Energy from atoms colliding or being split apart. |
Wind Energy | Energy collected from big turbines standing tall. |
