Minerals & Rocks
This naturally occurring, solid substance is made of one material with the same composition throughout and recognizable physical properties.
What is a mineral?
The continuous set of processes that shows how rocks change from one type to another through heating, cooling, weathering, erosion, pressure, and sedimentation.
A rock formed when hot, melted rock (magma or lava) cools and hardens.
What is igneous rock?
The solid mass made of one or more minerals stuck together; the basic building blocks of Earth's crust.
What is a rock?
The breaking down of rocks and minerals at Earth's surface by wind, water, temperature changes, or chemicals into smaller pieces, called sediment, or altered material.
What is Weathering?
A rock made from bits of other rocks, minerals, or plant pieces that become buried, compacted, and stuck together in layers.
What is sedimentary rock?
The external, regular geometric shape formed when atoms in a solid arrange in a repeating, orderly internal pattern.
What is a crystal?
The process that moves weathered rock and soil from one place to another by wind, water, ice, or gravity.
What is erosion?
A rock that was changed by heat and pressure into a new rock with different texture or mineral make-up.
What is metamorphic rock?
When small pieces of rock, mineral grains, or organic material settle out of water or air and are deposited in layers at a new place.
What is sedimentation?
Identify which rock type can form from the cooling of magma beneath Earth's surface and tends to have larger, visible crystals.
What is intrusive igneous rock?
Name the physical property that describes how shiny or dull a mineral is
What is luster?
The force applied to a rock or material from above or around it that contributes to compaction and metamorphism.
What is pressure?
Explain (in one or two sentences) how a sedimentary rock could become an igneous rock
"A sedimentary rock can be buried and subjected to heat, melt into magma, then cool and solidify to form an igneous rock."
