Unit 2 Vocabulary - Chemistry
Term | Definition |
Diffusion | The movement of molecules from an area of high concentration to low concentration, |
Particle Movement | movement of particles in all directions and a different speeds |
First Law of Thermodynamics | Energy cannot be created or destroyed, only transformed to another form. |
Second Law of Thermodynamics | Entropy of the universe is always increasing |
Plate boundaries | a fracture that separates one plate from another |
Earthquakes | shaking and vibration of the Earth's crust due to movement of the Earth's plates (plate tectonics) |
S-waves | Transverse waves that travel through only solids, slower than p-waves |
P-waves | Longitudinal/Compression waves that travel through gas, liquid, and solid, fastest waves |
Body Waves | Travel through the Earth’s interior and happens twice in bursts |
Surface Waves | Travel across the surface/crust of the earth, travel slowest → more damage |
Convergent Boundaries | Two continental plates collide and mountain ranges are formed with deep earthquakes |
Divergent Boundaries | moving away from each other allows magma to push up through the crust and form new, young crust. Has shallow earthquakes and makes mid-ocean ridges and young sea floor |
Transform Boundaries | Transform boundaries are places where plates slide sideways past each other and has shallow earthquakes. |
Convection | Transfer of heat through liquid |
Conduction | transfer of heat by contact |
Radiation | Transfer of thermal energy by contact |
Continental crust | older, thicker, less dense, and make up the earth’s continents |
Oceanic Crust | younger, thinner, more dense, makes up the earth’s ocean floor, and sinks lower |
Entropy | amount of disorder in a system |
