Minerals
The feel of a rock’s surface.
Texture.
Rock that forms when hot liquid rock material cools and hardens into a solid.
Igneous Rock.
The breaking down of rocks through chemical reactions such as acid rain and oxidation.
Chemical Weathering.
Molten rock inside of the earth.
Magma.
Water that soaks into soil and rock by collecting in spaces between rocks.
Groundwater.
How minerals reflect light.
Luster.
A solid made of one mineral or a mixture of many minerals.
Rock.
The dropping off of particles and sediment from weathering and erosion.
Deposition.
Molten rock outside of the earth.
Lava.
The bits and pieces of rocks broken off from weathering.
Sediment.
Naturally occurring solids with definite structures and properties.
Minerals.
A continuous process where rocks are constantly changing from one kind to another.
Rock Cycle.
Rocks are broken down by physical and chemical changes.
Weathering.
Formed below the Earth’s surface.
Intrusive Igneous Rock.
Substances that water is able to pass through such as sand and gravel.
Permeable.
The color powder left when a mineral is rubbed against a hard and/or rough surface.
Streak.
The type of rock that forms deep underground where great heat and pressure occur.
Metamorphic Rock.
Picking up and removing rock fragments and other particles; the carrying away of sediment.
Erosion.
I - - E - - S!
I-G-N-E-O-U-S, IGNEOUS, ROCKS!
Substances that water is unable to pass through.
Impermeable.
A measure of how easily a mineral can be scratched; a diamond is the hardest mineral and talc is the softest mineral.
Hardness.
The bits and pieces that are clumped together by pressure and are cemented together.
Sedimentary Rock.
The breaking down of rocks through physical changes such as frost action, abrasion of moving water, and blown sand.
Mechanical Weathering.
Formed above ground.
Extrusive Igneous Rock.
