Question | Answer |
---|---|
Middle layer of Earth | Mantle |
Thickest Layer of Earth | Mantle |
Top part of the mantle and the crust above it. | Lithosphere |
Center and hottest layer of Earth | Core |
Topmost, very thin layer of Earth | Crust |
Process of placing sediment in a new location | Deposition |
Process of moving sediment from one place to another | Erosion |
Process in which soil, sand, and sediment are formed | Weathering |
Rigid block of crust and upper-mantle rock | Plate |
Opening in the crust through which lava flows | Volcano |
Places where pieces of the crust move | Fault |
Hot, soft rock from the lower mantle | Magma |
Shaking of ground from energy release in the crust | Earthquake |
Remains or traces of past life found in the crust | Fossils |
Fast Changes to Earth's Surface | Volcano, Earthquake, and Tsunami |
Slow Changes to Earth's Surface | waves, weather, shifts in land, weathering, erosion, and deposition |
a natural non living , solid material that has particles in a repeating pattern | mineral |
made up of one or more minerals | rock |
forms when rock pieces are depostied and squeezed and stuck together | sedimentary rock |
the repeating processes that change rocks from one type to another over time | rock cycle |
rock changed by heat and pressure | metamorphic rock |
magma cools and hardens to form this type of rock | igneous rock |

a mineral property that describes the way light reflects from the mineral's surface | luster |
a mineral's ability to resist being scratched is its | hardness |
the layer of the soil that contains many minerals | Topsoil |
Processes that together form dunes, valleys and deltas | Erosion and Deposition |
