earth scie

or magmatic rocks are formed through the cooling and solidification of magma or lava.

this type of igneous rock are formed from solidification of magma below the surface that have large crystals of minerals that formed overtime thru slow process of crystallization in a magma.

this type of igneous rock is formed through faster rate of solidification of lava on the surface of earth. they can become glassy in appearance due to less crystallization or vesicular like scoria

is formed by the deposition and cementation of mineral or organic particles on the floor of oceans and other bodies of water at the Earth surface. ____ can be classified into clastic, chemical and organic.

it is formed from the mechanical weathering debris of rocks

it is formed when dissolved materials precipitate from solution

.Formed from the build-up of plant or animal debris.

Examples of this type are coal and fossiliferous limestone.

forms from existing rock types called “parent rock” in the

process called metamorphism, which means change in form. The original rock

which can be an igneous, sedimentary or another metamorphic rock is subjected

to heat and pressure, causing a profound chemical or physical change.

formed thru pressure due to compression of rocks that create bands called foliation.

it has no foliation of bands.
