Igneous rocks are one of the three main types of rocks found on Earth, the other two being sedimentary and metamorphic rocks. These rocks form from the solidification and cooling of molten material, known as magma, which originates deep within the Earth's crust and occasionally even in the mantle. The term "igneous" comes from the Latin word "ignis," meaning fire, highlighting the fiery origin of these rocks.

Conglomerate is a clastic sedimentary rock composed of rounded clasts that are over two millimeters in size and bound together by a cement that is usually composed of calcite or quartz.

Illustrated overview and examples of igneous rocks: basalt, granite, obsidian, pumice, gabbro, porphyry...

Granite has a coarse texture, while basalt has a smooth texture because the size of crystals of minerals forming granite is large, while the size of crystals
