1
minerals A naturally occurring, inorganic solid that has a definite chemical composition and crystal shape
2
inorganic Not formed from living things or the remains of living things
3
physical properties Can be observed or measured in order to describe or identify a substance
4
rock Hard substance made of one or more minerals
5
metamorphic rock Rock formed from heat, and pressure
6
igneous rock Rock formed when magma or lava cools and hardens
7
extrusive rock An igneous rock formed from a volcanic eruption
8
intrusive rock Formed from magma that has cooled and hardened inside the Earth
9
sedimentary rock Rock formed from the compacting and cementing of sediment
10
weathering The breaking down of rocks into sediment
11
sediment Fragmented material formed from rocks broken down by weathering
12
erosion Movement of sediment from one place to another
13
deposition Sediment is deposited, or laid down, in new places
14
compaction Sediment is squeezed together
15
cementation Sediment begins to stick together
16
rock cycle The continuous change of rocks from one type to another
17
uplift The process that moves large bodies of Earth’s material to higher elevations
18
Physical weathering The process that breaks down rocks and minerals without changing their compositions
19
Chemical weathering The process that changes the compostion of rocks and minerals due to exposure to the environment
20
Mass wasting The downhill movement of a large mass of rocks or soil due to gravity
21
glacier A large mass of ice that moves slowly across Earth’s surface
22
Thermal expansion/contraction
The heating and cooling of rocks causing them to break
