Types of rocks Flashcards
Cycle
A cycle is like a circle of a series of things that transform in other.
Deposit
A mineral deposit is a natural concentration of minerals in the earth’s crust.
Erosion
Erosion is the geological process in which earthen materials are worn away and transported by natural forces such as wind or water.
Extrusive
Extrusive rock, any rock derived from magma that was poured out or ejected at Earth’s surface.
Fossil
A fossil is any preserved remains, impression, or trace of any once-living thing from a past geological age.
Igneous rock
Sometimes volcanoes form at these weak spots. Hot, melted rock pushes up through the volcanoes and flows out over Earth’s surface. When this melted rock cools and hardens, it forms igneous rocks.
Intrusive
Intrusive rock, igneous rock formed from magma forced into older rocks at depths within the Earth’s crust
Lava
Material that go outside when a volcano explode.
Magma
Magma is extremely hot liquid and semi-liquid rock located under Earth’s surface.
Metamorphic
Is the cycle of rocks.
Metamorphic rocks
Metamorphic rocks form when heat and pressure produce changes in igneous rocks, sedimentary rocks, or other metamorphic rocks.
Pressure
Continuous physical force exerted on or against an object by something in contact with it.
Rock
A rock is a solid mass of geological materials.
Rock cycle
The rock cycle is a concept used to explain how the three basic rock types are related and how Earth processes.
Sediment
Matter that settles to the bottom of a liquid
