Igneous rocks are formed when the solidification process of molten rock material. There are two different types of igneous rocks, intrusive which solidify below the Earth's surface and extrusive which solidify on or above the Earth's surface.
Weathering & Erosion
The process when rock is dissolved worn away or broken down getting smaller and smaller pieces.
Transport & Deposition
The process where sediments, soil, and rocks are added to a landforms mass. Wind, ice, and water transport fluid, building up layers.
Is the tendency for particles in suspension to settle out of the fluid in which they are entrained, and come to rest against a barrier.
Compaction & Cementation
When pressure from weight from the sediments are deeply buried to squish the grains together tightly. Cementation is where the materials stick the grains together.
This category is formed by the deposition of materials at the Earth's surface and within bodies of water.
Burial, high temperature and pressure
When sedimentary rocks are buried to depths of several hundred meters. Burial metamorphism overlaps, to some extent, metamorphism as temperature and pressure increase.
Arise from the transportation of existing rock types, in a process called metamorphism. which means "change in form".
Most magma that reaches the surface in volcanic eruptions comes from a part of Earth's mantle called the atmosphere. Melting is when the solid turns to a liquid with high temperatures.
Magma from Molten Crust & Mantle
The differences in temperatures, pressure, and formation. Most mantle and crust are solid, so the presence or magma is crucial.
is a molten and semi- molten rock mixture found under the surface of the Earth.
