Aftershock: An earthquake that occurs after a larger earthquake in the same area.
Earthquake: The shaking that results from the movement of rock beneath Earth's surface.
Magma: The moten mixture of rock-forming substances, gases, and water from the mantle.

Unit 2 Vocabulary
Weathering: The breaking down of rock through chemical or physical means. This broken down rock is called sediment (silt, clay, sand, gravel, cobble etc.)
Erosion: The carrying away of the broken down bits of rock called sediment from its original source.
Deposition: the process of sediment dropping out of a moving fluid as it slows down such as running water or wind.
Sedimentary Rock: Rocks that are made out of sediment.
Rock Cycle: A series of processes on the surface and inside the earth that slowly changes rocks from one kind into another.
Igneous Rock: A type of rock that form from the e cooling of molten rock at or below the surface.
Metamorphic Rock: A type of rock that forms from an existing rock that is changed by heat, pressure, or chemical reactions.
Mineral: A naturally occurring, inorganic solid that has a crystal structure and a definite chemical composition.
Intrusive (Igneous) Rock: Igneous rock that forms when magma hardens beneath earth's surface.
Extrusive (Igneous) Rock: Igneous rock that forms when lava hardens above the earth's surface.
Fossil: the preserved remains or traces of living things.
Paleontologist: A scientist who studies fossils to learn about organisms that lived long ago.
