Sedimentary rocks are formed by the accumulation of sediments. There are three basic types of sedimentary rocks. Clastic sedimentary rocks, Chemical sedimentary rocks, and Organic sedimentary rocks. Sedimentary rocks are types of rock that are formed by the deposition and subsequent cementation of that material at the Earth's surface and within bodies of water. Sedimentary rocks can be divided into two major categories: clastic and precipitated .

Sedementary Rock

Rock cycle- is a group of changes. Igneous rock can change into sedimentary rock or into metamorphic rock. Sedimentary rock can change into metamorphic rock or into igneous rock. Metamorphic rock can change into igneous or sedimentary rock. Igneous rock forms when magma cools and makes crystals.

Rock Cycle

By: Chris Gomez

How it’s made- They are formed by the cooling of molten magma on the earth's surface.

What factors affect rock melting point- The factors that mainly affect in the formation of magma can be summarized into three: Temperature, pressureand composition.


Chemical composition- Igneous rocks are commonly classified by their composition and texture. Most are composed of the eight most abundant elements in the Earth's crust.


Mafic/Felsic rock- felsic refers to igneous rocks that are relatively rich in elements that form feldspar and quartz. It is contrasted with mafic rocks which are relatively richer in magnesium and iron.


Where is it found mafic/felsic- Mafic rock is usually  found on oceanic plates at divergent plate boundaries. Felsic rocks can be found along continental margins.


What are mafic/felsic igneous rocks made of- Felsic rocks are rich in elements that form feldspar and quart. Mafic rocks are relatively richer in magnesium and iron.

How do igneous rocks affect society- They are formed by volcanos magma which really doen't affect the enviornment besides the magma when it is molting hot and kills everything in its path






Igneous Rocks

Metamorphic are modified by heat, pressure, and chemical processes, when buried deep below Earth's surface. Exposure to these extreme conditions has changed the mineralogy, texture, and chemical composition of the rocks.
