| convection | transfer of heat though liquids or gases |
| conduction | transfer of heat through direct contact of particles of matter |
| radiation | transfer of heat through empty space |
| lithosphere | composed of the uppermost part of the mantle and the crust |
| asthenosphere | semi rigid part of the middle mantle that flows like thick syrup |
| indirect evidence | seismic waves |
| direct evidence | rock samples |
| crust | rocky layer of the earth that includes the oceans, dry land |
| outer core | layer of earth made of liquid nickel and iron |
| inner core | layer of earth made of solid nickel and iron |
| mantle | layer of earth that includes molten rock |
| magnetic field | created by the movement within earth's liquid outer core |
| poor heat conductors | plastic, wood, glass |
| density | how much mass is in an object |
| An increase in temperature causes this | Denisty decreases |
| An increase in density is a result of this | temperature decrease |
