Rock Transformations

what is A

metamorphic

what is B

Magma

what is C

igneous rock

what is D

sediment

what is E

sedimentary rock

What do we call rocks that form from cooling magma?

igneous rock

Which process leads to the formation of sedimentary rocks?

compaction and cementation

What is required for a rock to become metamorphic?

heat and pressure

Which type of rock might contain fossils?

sedimentary rock

if you find a rock with layers of sand and tiny pebbles, it is most likely

sedimentary rock

what is it called when magma cools underground

intrusive

what is it called when magma cools outside

extrusive

the way sedimentary rock forms

compaction and cementation

what does metamorphic rock cause

recrystallization or banding

what is the crystal size of extrusive igneous rock

small/none

what is the crystal size of intrusive igneous rock

big

Rocks break into smaller pieces

weathering

Sediments are moved by water, wind, or ice

erosion

Sediments settle in new locations

deposition

Sediments turn into sedimentary rock

compaction and cementation

Existing rock becomes metamorphic

metamorphism

Rock turns into magma

melting

Magma/lava solidifies into igneous rock

cooling

what powers weathering, erosion, deposition

the sun

what powers melting, pressure, and metamorphism

the earth’s interior

what powers sediment layering

gravity

Volcanic eruptions → extrusive rock

fast process

Landslides → quick movement and redeposition of sediment

fast process

Earthquakes → rapid changes in landscape

fast process

Weathering and erosion over long periods

slow process

Mountain building through plate collisions

slow process

intrusive rock forming underground

slow process

Formation of sedimentary layers

slow process

Which type of rock forms from heat and pressure?

metamorphic

Large crystals in an igneous rock indicate

slow cooling

Fossils are MOST likely found in

sedimentary rock
