100

How does a sedimentary rock turn into a metamorphic rock. 

Heat and pressure

100

Remains, impressions, or any other evidence of a plant or animal preserved in rock

Fossils

100

Formed when hot, molten rock crystalizes and solidifies

Igneous

100

A dark, coarse-grained plutonic rock of crystalline texture, consisting mainly of pyroxene, plagioclase feldspar, and often olivine.

Gabbro

100
A fine-grained metamorphic rock with a well-developed laminar structure, intermediate between slate and schist in degree of metamorphism.

Phylitte

200

How does a igneous rock turn into a metamorphic rock

Heat and pressure

200

Sand patterns formed by the actions winds, streams, waves or currents.

Ripple Roots

200

formed from pre-existing rocks or pieces of once-living organisms

Sedimentary rocks

200

An ammonium picrate explosive used as a bursting charge for armor-piercing projectiles and in high-explosive shells

Dunnite 

200

a fine-grained gray, green, or bluish metamorphic rock easily split into smooth, flat pieces.

Slate

300

How does a metamorphic rock turn into magma

Melting

300

Round, solid masses of calcium carbonate found in layers of shale

Concretions

300

 started out as some other type of rock, but have been substantially changed from their original rock

Metamorphic rock

300
A dark, fine-grained volcanic rock that sometimes displays a columnar structure. It is typically composed largely of plagioclase with pyroxene and olivine.


Basalt

300
a coarse-grained meamorphic rock which consists of layers of different minerals and can be split into thin irregular plates.


Schist

400

How does a igneous rock turn into sediments

Weathering and erosin

400

Within the hardened air bubbles of igneous rocks or in limestones, interiors may be lined or filled with crystals of quartz or calcite

Geode

400

a common, coarse-grained, hard igneous rock consisting chiefly of quartz, orthoclase or microcline, and mica.

Granite

400

a common, coarse-grained, hard igneous rock consisting chiefly of quartz, orthoclase or microcline, and mica.

Granite

400

a hard crystalline metamorphic form of limestone, typically white with mottlings or streaks of color, that is capable of taking a polish and is used in sculpture and architecture.

Marble

500

How does a metamorphic rock turn into sediments

Weathering and erosin

500

Wet clay dries and contracts. The cracks are filled with different sediments and over time, fossilized. 

Mud Cracks

500

 made from magma that erupted out of a volcano

Obsidian

500

made from magma that erupted out of a volcano

Obsidian

500

a metamorphic rock with a banded or foliated structure, typically coarse-grained and consisting mainly of feldspar, quartz, and mica.
