S Flashcards
A volcanic rock formed from the cooling of magma
Igneous Rock
A rock formed from the compaction and cementation of sediment
Sedimentary Rock
A rock formed from high heat and pressure
Metamorphic Rock
Are there fossils in igneous rocks
No
Are there crystals in igneous rocks
yes
An igneous rock formed from magma under the Earth’s surface
Intrusive Igneous rock
An igneous rock formed from magma (lava) on the Earth’s surface
Extrusive Igneous rock
Quick to cool with small crystals
Extrusive
Slow to cool with large crystals
Intrusive
Examples of an intrusive Igneous Rock
Granite and Gabbro
Examples of an extrusive Igneous Rock

Sedimentary rock
Are there crystals in Sedimentary rocks
No
Examples of a sedimentary rock
Limestone, Sandstone and Coal
Are there crystals in metamorphic rocks
Yes (ordered crystals)
Could there be fossils in metamorphic rocks
Yes (there could be fossil)
A rock that is dense and hard
Metamorphic Rock
Examples of a metamorphic rock
Marble, Slate and Gneiss
A rock that is hard and volcanic
Igneous Rock
Types of erosional transport
Wind, Water and Ice
Deposition
The action of depositing sediment
Compaction and Cementation
The process of squishing air and water into the particles of sediment and sticking grains of sediment together.
Three types of weathering
Physical, Chemical and Biological
Examples of Biological Weathering
Tree roots, lichen and moss
Examples of Chemical Weathering
Water reacting (acid water or acid rain)
Examples of Physical Weathering
People, wind, animals and water force
What is a fossil?
The impression of animals and plants left in rocks from millions of years ago
Dung, Tracks and Burrows
Traces of Fossils
What rock are fossils mostly found in
Sedimentary
Imprints and indented marks of fossils
Impressions of Fossils
Parts and whole remains of fossils
Preserved Fossils
