Cycle
A series of events that are regularly repeated in the same order.
Deposit
An accumulation or layer of solid material, either consolidated or unconsolidated, left or laid down by a natural process.
Erosion
The gradual destruction or diminution of something.
Extrusive
Relating to or denoting rock that has been extruded at the earth’s surface as lava or other volcanic deposits.
Fossil
Fossils are the remains of plants, animals, fungi, bacteria, and single-celled living things that have been replaced by rock material or impressions of organisms preserved in rock.
Igneous rock
Igneous rocks (from the Latin word for fire) form when hot, molten rock crystallizes and solidifies. The melt originates deep within the Earth near active plate boundaries or hot spots, then rises toward the surface.
Intrusive
Intrusive rock is formed when magma penetrates existing rock, crystallizes, and solidifies underground to form intrusions, such as batholiths, dikes, sills, laccoliths, and volcanic necks.
Lava
Lava is molten rock generated by geothermal energy and expelled through fractures in planetary crust or in an eruption , usually at temperature from 700 to 1200 celcius .
Magma
Magma is extremely hot liquid and semi-liquid rock located under Earth’s surface. … This magma can push through holes or cracks in the crust, causing a volcanic eruption.
Metamorphic
metamorphic. [ mĕt′ə-môr′fĭk ] Zoology Relating to metamorphosis. Geology Relating to rocks that have undergone metamorphism.
Metamorphic rock
Metamorphic rocks are formed from other rocks that are changed because of heat or pressure.
Pressure
Pressure, in the physical sciences, the perpendicular force per unit area, or the stress at a point within a confined fluid
rock
A rock is any naturally occurring solid mass or aggregate of minerals or mineraloid matter.
rock cycle
The rock cycle is a concept used to explain how the three basic rock types are related and how Earth processes, over geologic time, change a rock from one type into another.
Sediment
matter that settles to the bottom of a liquid; dregs.
Sedimentary rock
Rock that has formed through the deposition and solidification of sediment, especially sediment transported by water (rivers, lakes, and oceans), ice (glaciers), and wind.
Texture
The texture of a rock is the size, shape, and arrangement of the grains (for sedimentary rocks) or crystals (for igneous and metamorphic rocks).
Weathering
The process of wearing or being worn by long exposure to the atmosphere
