Igneous rock
A substance igneous rocks are made from
Magma or lava
A word beginning with 'D' that describes the laying down of sediment
Deposition
Two physical conditions involved in the formation of metamorphic rock
Heat and pressure
A rock type which contains fossils
Sedimentary rock
A scale measuring rock hardness
Moh's scale
The igneous rock type most likely to form with 'air bubbles; or small pockets of gas
An example of a sedimentary rock
Shale, limestone, sandstone, conglomerate, chalk, mudstone, dolomite, and more!
The cause of visible folds (also called banding and foliation) in some metamorphic rocks
Pressure
The difference between weathering and erosion
Weathering --> breaking
Erosion --> moving
A term used to describe the colour of a mineral left behind when scratched against another surface or ground into powder form
Streak
Fine grain or an even glassy texture is usually a sign of what speed of cooling during igneous rock formation?
Quick
Where the oldest sedimentary rock would be found in a vertical sample of earth
At the bottom / the lowest layer
An example of a metamorphic rock
marble, gneiss, slate, schist, quartzite, and more!
Two different types of weathering
Chemical and physical
Most common rock type in the Earth's crust
Igneous rock
The igneous rock type most likely to form large crystals
Intrusive
A sedimentary rock that is metamorphosed into marble
Limestone
One possible types of pressure involved in metamorphic rock formation
Direct pressure or shear stress
A rock type commonly formed from fragments of shells of small, fossilised snails, shellfish, bones, and coral over millions of years
Sedimentary rock
A rock band whose name was inspired by electrical power sources
ACDC
Alternating Current / Direct Current
An example of an igneous rock
Obsidian, granite, pumice, basalt, gabbro, rhyolite, and more!
Two words, both beginning with 'C', that describe the final stages of sedimentary rock formation
Compaction and cementation
Crystals are more aligned and compact with increased pressure
Formed from the weathering and erosion of rock
Sediment
The Earth's largest single rock monolith (the largest single rock)
