semester 1 & 2 vocab

Thermal energy The total kinetic and potential energy of all the particles of an object.
Nuclear energy the potential energy stored in the nucleus of an atom.
Energy Transformation A change from one form of energy to another.
Chemical energy A form of potential energy that is stored in chemical bonds between atoms.
Kinetic energy Energy that an object has due to its motion.
Alt energy source energy such as solar, wind, or nuclear energy, that can replace fossil-fuel sources such as coal, oil, and natural gas.
Gravity The attractive force between objects; the force that moves objects downhill
Average speed The overall rate of speed at which an object moves; calculated by dividing the total distance an object travels by the total time.
Balanced forces Two forces acting in opposite directions.
Potential energy The energy an object has because of its position.
Fossil fuels Coal, oil, or natural gas that forms over millions of years from the remains of ancient organisms; burned to release energy.
Conduction The transfer of thermal energy from one particle of matter to another.
Radiation The transfer of energy by electromagnetic waves.
Friction The force of two surfaces expert on each other when they rub against each other.
convection the transfer of thermal energy by the movement of liquid.
Continental Drift The hypothesis that the continents slowly move across Earth’s surface.
Erosion The process by which water, ice, wind, or gravity moves weathered particles of rock and soil.
Organelle A tiny cell structure that carries out a specific function within the cell.
Plant cell Eukaryota cells, or cells with a membrane-bound nucleus.
Animal cell Eukaryota cells, or cells with a membrane-bound nucleus.
Faults A break in Earth’s crust along which rocks move.
Unicellular A single cell that carries out life.
Earthquake The shaking that results from the movement of rock beneath Earth’s surface.
Rock cycle A series of processes on the surface and inside Earth that slowly changes rocks from one kind to another.
Plate tectonics The theory that pieces of Earth’s lithosphere are in constant motion; driven by convection currents in the mantle.
Cell the smallest unit of life that can replicate independently
Mantle The layer of hot, solid material between Earth’s crust and core.
Sedimentary Rock type that forms when particles from other rocks or the remains of plants and animals are pressed and cemented together.
Mitosis The second stage of the cell cycle during which the cell’s nucleus divides into two new nuclei and one set of DNA is distributed into each daughter cell.
Multicellular Multiple cells that carry out life.
