- compaction
- compression of lower layers of sediment due to the weight of the layers above them.
- conglomerate
- a detrital rock made from well rounded sediments.
- cementation
- the gluing together of large sediments by mineral deposited between them.
- intrusive
- igneous rocks that form when magma cools below the Earth's surface.
- chalk
- fossil-rich limestone with microscopic shells.
- sediment
- loose materials such as rock fragments, mineral grains, and bits of organic matter transported by the agents of erosion.
- shale
- detrital sedimentary rock made from clay-sized particles.
- halite
- a key component of rock salt.
- detrital sedimentary rock
- made from the broken fragments of other rocks.
- metamorphic rock
- rock formed from sedimentary, igneous or other metamorphic rock due to increases in heat and pressure.
- basaltic
- dark colored, dense igneous rock that form from magma rich in iron and magnesium.
- slate
- a foliated metamorphic rock formed from shale.
- organic sedimentary rock
- rocks formed from the remains of once living things.
- rock cycle
- model showing the three types of rocks and how they are formed.
- sandstone
- sedimentary rock formed from sand-sized mineral sediments, often quartz and feldspar.
- foliated
- metamorphic rock that shows parallel bands
- granitic
- light colored igneous rocks formed from magma rich in silicon and oxygen.
- quartzite
- nonfoliated metamorphic rock formed from sandstone.
- clastic
- broken
- limestone
- calcite based sedimentary rock usually deposited on seafloor
- sedimentary rock
- rock formed when fragments of rock, minerals, and/or organic matter are compacted or cemented together or precipitate out of solution.
- lava
- magma reaching the Earth's surface.
- marble
- a nonfoliated metamorphic rock formed from limestone.
- extrusive
- igneous rocks that form when lava cools.
- nonfoliated
- metamorphic rock that does not have bands.
- breccia
- a detrital rock made from angular sediment.
- igneous rock
- rocks formed by the cooling and hardening of molten material from a volcano or from deep inside Earth.
- rock
- a mixture of minerals, mineraloids, glass, or organic matter.
- coal
- sedimentary rock formed when pieces of dead plants are buried under other sediments in swamps.
- coquina
- fossil-rich limestone with large shell fragments.
- chemical sedimentary rock
- formed when minerals precipitate from a solution or are left behind after solution evaporation
