what is the definition of magma
melted rock
100
what are the 4 types of rocks in the rock cycle
1. extrusive igneous 2. intrusive igneous 3.sedimentary 4.metamorphic
200
what does it mean when a metamorphic rock is labeled low grade/quality.
it has been exposed to low heat and pressure
200
when lava cools on earths surface it creates a ------- igneous rock
extrusive
200
layers in rocks are called -----
strata
200
what is the definition of a intrusive igneous rock
when magma cools below the surface and creates s rock

what is the definition of lithifacation
to cement and compact sediments to gether
300
when there is unequal pressure on a rock it becomes a ------ metamorphic rock
foliated
400
what types of rocks can become metamorphic
igneous,sedimentary and metamorphic
400
what are the 2 types of igneous rocks?
intrusive and extrusive
400
what are the 3 types of sedimentary rocks
clastic,organic and chemical
400
what does foliated mean
layers
400
what can cause weathering
wind water and ice
500
what are the steps to create a metamorphic rock?
1.any type of rock is exposed to heat and pressure 2.then its a metamorphic rock
500
what are the steps to create an igneous rock? (there are 2 types of igneous rocks)
1.rocks melt into magma 1.rocks melt into magma 2.magma cools underground 2.magma comes to the 3.an intrusive igneous rock forms surface and becomes lava 3.lava cools 4. an extrusive igneous rock forms
500
what are the steps to create sedimentary rocks?
1.rocks are weathered into sediment 2.sediment is moved by erosion 3.deposition or the deposit of minerals 4.sediments are layered on top of each other 5.sediments are cemented and compacted together 6. finally strata will show in the new rock
500
what is a delta
a fan shaped deposit at the mouth of a river
500
what does metamorphic mean
to change form
