a mixture of such minerals , rock fragments, volcanic glass, organic matter or other natural materials.
What is a rock
100
Igneous rocks that are dense and dark colored. Form from magma that is rick in iron and magnesium
What is Basaltic

Three types of rocks
What are igneous, metamorphic and sedimentary
200
Thick, gooey, molten material inside a volcano or deep inside Earth
What is Magma

When mineral grains line up in parallel layers the metamorphic rock is
What is foliated

When magma reaches the surface it becomes
What is lava?
300
the slow change of rocks over time
What is the rock cycle?
300
Are light colored and have lower density. Form from thick stiff magma that contains lots of silica and lesser amounts or iron and magnesium
What is granitic
300
mineral grains grow and rearrange but they do not form layers
What is nonfoliated?
300
formation of detrital rocks by layers of small sediments ing together because of pressure
What is Compaction?
300
Igneous rocks that form from lava cooling quickly at the surface of the earth
What are extrusive igneous rocks
400
location where scientists first recognized the rock cycle
What is Siccar Point, Scotland
400
Igneous rocks that have mineral compositions between those of granitic and basaltic rocks
What is andesic rocks
400
Processes that change rocks
What are heat, pressure and hot fluids?
400
are made from remains of once living plants or animals
What are organic sedimentary rocks?
400
One kind of volcanic glass that has holes caused by pockets of gas
What is pumice and scoria?
500
rock fragments, mineral grains, or organic remains that have been moved by wind, water, ice or gravity
What are sediments
500
igneous rock that forms below Earth's surface
What is intrusive rock
500
Slate and Gneiss are examples of
What is foliated rock
500
Formation of detrital rocks by the movement of water and other minerals through open spaces between larger sediments, gluing them together.
What is cementation?
500
The principle that states the rock cycle never destroys elements of rocks only redistributes them is known as
