· A lot of people think rocks and minerals are the same thing, but they really are not. To a geologist, the simple difference between rocks and minerals is that rocks consist of minerals. For example, granite is a rock that contains the minerals feldspar, quartz, and sometimes mica, biotite, and hornblende. The minerals form an

The types and proportions of minerals in a rock determine its mineral composition. Texture: Rock texture refers to the size, shape, and arrangement of mineral grains or crystals within a rock. Texture can be classified as fine-grained, coarse-grained, glassy, porphyritic (containing both large and small crystals), or vesicular (containing cavities or

· Phaneritic: Coarse-grained texture due to slow cooling (typical of plutonic rocks). Granite is a common example of a phaneritic igneous rock. This rock has large, visible crystals of minerals such as quartz, feldspar, and mica. Aphanitic: Fine-grained texture due to rapid cooling (typical of volcanic rocks).

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.

In geology, rock (or stone) is any naturally occurring solid mass or aggregate of minerals or mineraloid matter. It is categorized by the minerals included, its chemical composition, and the way in which it is formed.Rocks form the Earth's outer solid layer, the crust, and most of its interior, except for the liquid outer core and pockets of magma in the asthenosphere.

The rock cycle describes how rocks on Earth form and change over time. When rocks are pushed deep below Earth’s surface, they can melt to form magma. Magma that reaches Earth’s surface through volcanic activity is called lava. Igneous rocks form when magma or lava cools and solidifies. Weathering breaks igneous and other types of rocks into

· Intrusive (or, plutonic) igneous rocks form from magma that has cooled below the Earth's surface. Because this cooling process is slow, visible (or, phaneritic) mineral grains have time to form and are usually visible with the naked eye.
