| Question | Answer |
| made of magma or molten (melted rock). Flows like hot, thick oatmeal. | mantle |
| the outer layer of the earth that is made of rock | crust |
| made of liquid metals: iron and nickel | outer core |
| is very hot, is kept solid due to great pressure | inner core |
| when wind, rain , ice or plant roots slowly break down rocks and wears down Earth's surface | weathering |
| when rain, wind, ocean waves or glaciers slowly move soil and rocks | erosion |
| when soil and rock that was moved by erosion is left piled up in a new place | deposition (deposit) |
| is formed by the weathering of rocks and shells | sand |
| an impression left in sedimentary rock by the remains of a dead plant or animal | fossil |
| the natural processes by which rocks are created and changed to form new rocks | rock cycle |
| rocks that are formed when melted rock (magma) cools and hardens, either above or below the Earth's surface | igneous rocks |
| rocks formed over time by hardening of layers of sediments like mud, shell particles, pieces of bone and rock fragments | sedimentary rocks |
| rocks formed when heat and pressure change one kind of rock into another | metamorphic rock |
| build up the Earth's surface (lava flow, the folding of the Earth's crust into mountains) | constructive forces |
| forces that tear down Earth's landforms (weathering, erosion, glaciers and earthquakes) | destructive forces |
