Igneous Rock

Igneous rocks are formed through the cooling and solidification of magma or lava. Magma is molten rock found beneath the Earth's surface, and lava is molten rock that has erupted onto the surface.

Intrusive Igneous Rock.

Forms when magma cools slowly beneath the Earth's surface. This slow cooling allows large crystals to form, resulting in a coarse-grained texture.

Extrusive Igneous Rock

Forms when lava cools quickly on the Earth's surface. This rapid cooling results in fine-grained or glassy textures.

Sedimentary rock

Sedimentary rocks are formed from the accumulation and compaction of sediment, which can include fragments of other rocks, minerals, and organic material. These sediments are often deposited in layers and compacted over time.

clastic sedimentary rocks

esvinyuman82 — 2024-07-01 20:21:00 UTC

Made from fragments (clasts) of other rocks that are compacted and cemented together.

Organic Sedimentary Rocks:

formed from the accumulation of plant or animal debris.

Chemical Sedimentary Rocks

esvinyuman82 — 2024-07-01 20:35:57 UTC

Form from the precipitation of minerals from water.

Metamorphic Rock

esvinyuman82 — 2024-07-01 20:40:54 UTC

Metamorphic rocks are formed from existing rocks (igneous, sedimentary, or other metamorphic rocks) that are subjected to high heat, high pressure, or chemically active fluids, resulting in physical and chemical changes.

Foliated Metamorphic Rocks

esvinyuman82 — 2024-07-01 20:44:07 UTC

Have a layered or banded appearance due to the alignment of mineral grains under pressure.

Non-Foliated Metamorphic Rocks

esvinyuman82 — 2024-07-01 20:48:49 UTC

Do not have a layered appearance. They are typically formed under conditions of high heat but relatively low pressure.
