Hodge Podge
100
Naturally formed solid that is usually made up of one or more minerals
What is a rock?
100
Forms when magma cools within Earth
What is an intrusive igneous rock?
100
Materials that settle out of water or air
What is sediment?
100
Process by which an existing rock is changed by heat and/or pressure
What is metamorphism?
100
Melted rock inside Earth
What is magma?
200
Forms when lava cools on Earth's surface
What is an extrusive igneous rock?
200
These two elements transport or carry sediment to places where rocks are formed
What are wind and water?
200
Process by which pressure can break bonds of atoms in minerals and then new bonds form to make new minerals
What is recrystallization?
200
Most common rock at Earth's surface
What are sedimentary rocks?
300
Forms when molten rock cools into a solid
What is an igneous rock?
300
Slow cooling time allows these to form to a large size
What are crystals?
300
Unusual sedimentary rock which is formed from remains of ancient plants
What is coal?
300
Arrangement of minerals in flat or wavy bands
What is foliation?
300
Limestone is this type of rock
What is a sedimentary rock?
400
Forms when heat and/or pressure causes oler rocks to change into new types of rocks
What is a metamorphic rock?
400
Lava that contains a great amount of this flows slowly
What is silica?
400
This sedimentary rock is formed from the shells and skeletons of ocean organisms
What is limestone?
400
Nonfoliated rock often used by artists because it won't shatter; it is easily sculpted
What is marble?
400
Lava rich in silica forms this shape of volcano
What is a cone-shaped volcano?
500
Forms when heat and/or pressure causes older rocks to change into new types of rocks
What is a metamorphic rock?
500
Rocks high in silica content will have this type of color
What is a light color?
500
One of three markings on a sandstone which indicate the action of past wind or water
What are crossbeds, ripples, and/or mudcracks?
500
Changes in metamorphic rocks over a large area can push these up to Earth's surface
What are mountains?
500
An unusual black rock with NO minerals
What is obsidian?
