Science 7 Vocab Quiz: Unit 3

in porous sediment, water deposits minerals which gradually fill the spaces between grains and bind them to one another to form rock

• cementation
• compaction
• cleavage
• hardness

rock made of minerals that were once dissolved in water, but have precipitated out

• chemical sedimentary rock
• clastic sedimentary rock
• organic sedimentary rock
• bedrock

the layer of solid rock located beneath the soil on Earth

• magma
• bedrock
• clastic sedimentary rock
• nonfoliated

the process of sediments being pressed more closely together by the weight of sediments above or by tectonic forces

• cementation
• extrusive
• compaction
• texture

occurs when preexisting rock comes into contact with magma underground and is metamorphosed by the heat or fluids of the magma

• cementation
• contact metamorphism
• regional metamorphism
• compaction

the splitting of rocks or crystals along preferred paths or planes

• cleavage
• hardness
• texture
• foliated

a naturally occurring, inorganic solid with a definite chemical composition and characteristic crystalline structure

• magma
• crystal
• intrusive
• mineral

a solid material made up of molecules that are arranged in repeating patterns

• bedrock
• lava
• mineral
• crystal

describes an igneous rock that forms from lava that cools quickly on Earth's surface, resulting in rocks with fine-grained, microcrystalline, or glassy textures

• foliated
• extrusive
• intrusive
• nonfoliated

a measure of how difficult it is to scratch a mineral

• hardness
• cleavage
• compaction
• cementation
