deposit

Back 1

sediment or rock added to a landform

Front 2

grain

Back 2

fragment that makes up a rock

Front 3

lava

Back 3

molten or liquid rock underground

Front 4

mineral

Back 4

naturally occurring,inorganic solid with a definite chemical composition and orderly arrangement of atoms

Front 5

rock

Back 5

natural, solid mixture of minerals or particles

Front 6

rock cycle

Back 6

series of processes that change one type of rock into another type of rock

Front 7

sediment

Back 7

rock material that is broken down into smaller pieces or dissolved in water as rocks erode

Front 8

texture

Back 8

grain size and the way grains fit together in a rock

Front 9

extrusive rock

Back 9

igneous rock that cools and crystallizes on Earth's surface

Front 10

intrusive

Back 10

igneous rock that forms as magma cools underground

Front 11

volcanic glass

Back 11

rock that forms when lava cools too quickly to form crystals

Front 12

biochemical rock

Back 12

sedimentary rock that was formed by organisms or contains the remains of organisms

Front 13

cementation

Back 13

crystallization of minerals from water into spaces between sediment grains

Front 14

chemical rock

Back 14

made of minerals that crystallizes directly from water

Front 15

clast

Back 15

broken piece or fragment of rock

Front 16

clastic rock

Back 16

sedimentary rock made of clast of minerals or rock fragments

Front 17

compaction

Back 17

process that squeezes out fluids and decreases the space between the grains in a sediment deposit

Front 18

contact metamorphism

Back 18

formation of a metamorphic rock caused by magma coming into contact with existing rock

Front 19

expose

Back 19

to appear visible

Front 20

foliated rock

Back 20

contains parallel layers of flat and elongated minerals

Front 21

metamorphism

Back 21

process that affects structure or composition of rocks in the solid state; occurs due to changes in heat, pressure, or the addition of chemical fluids

Front 22

nonfoliated rock

Back 22

nonfoliated rock has mineral grains with a random interlocking texture

Front 23

plastic deformation

Back 23

permanent change in rock shape caused by bending and folding

Front 24

regional metamorphism

Back 24

formation of metamorphic rock bodies that are hundreds of square kilometers in size
