Magmas that erupt at Earth's surface as lava flows, or as material that explodes into the air, cool quickly to produce extrusive rocks (so called because the magmas extrude at Earth's surface). Extrusive rocks contrast with intrusive rocks that crystallize slowly when magma cools underground. Figure 2.2 shows a sample of basalt, the most common kind of …

Slow cooling allows time for large crystals to form, so intrusive igneous rocks have visible crystals. Granite is the most common intrusive igneous rock (see Figure below for an example). Granite is made of four minerals, all visible to the naked eye: feldspar (white), quartz (translucent), hornblende (black), and biotite (black, platy).
Granite is the most common intrusive igneous rock.Igneous rocks make up most of the rocks on Earth. Most igneous rocks are buried below the surface and covered with sedimentary rock, or are buried beneath the ocean water. In some places, geological processes have brought igneous rocks to the surface. Yosemite is a classic example of …

Igneous rocks (from the Latin word for fire) form when hot, molten rock crystallizes and solidifies. The melt originates deep within the Earth near active plate boundaries or hot spots, then rises toward the surface. Igneous rocks are divided into two groups, intrusive or extrusive, depending upon where the molten rock solidifies.Intrusive Igneous …
Igneous rocks form from the cooling of magma – molten materials in the earth's crust. The terminology Igneous means fire or heat. In this sense, igneous rocks are formed when molten rock (magma) solidifies either …

Igneous rocks are "fire-born," meaning that they are formed from the cooling and solidification of molten (melted) rock. The word igneous derives from ignis, the Latin word for "fire." Molten rock …
The structural and textural aspects of igneous rocks frequently overlap, so for clarity in the present chapter, structure refers to the meso and macroscopic features of rock that are more easily observed in the field, and texture refers to microscopic aspects, such as the size (granularity) and shape (euhedral, subhedral and anhedral) of mineral …

igneous rock, Any of various crystalline or glassy noncrystalline rocks formed by the cooling and solidification of molten earth material (magma).Igneous rocks comprise one of the three principal classes of rocks, the others being metamorphic and sedimentary rocks. Though they vary widely in composition, most igneous rocks consist of quartz, …
The principle of inclusions. A rock that contains fragments or pieces of another rock must be younger than the pieces of rock that it contains.Sedimentary rocks can contain clasts of other rocks (such as pebbles in a conglomerate), or igneous rocks can contain xenoliths (foreign rock fragments; figure below) which were ripped from surrounding rocks by the …

Pegmatite. Pegmatite is a type of intrusive igneous rock formed during the last stages of magma crystallization. Its crystals are usually larger than 1 cm in size, and often much larger. The large crystal sizes in pegmatite are a result of that part of the magma body taking so long to cool, giving the crystals plenty of time to grow.

Igneous Rocks. Igneous rocks (fiery rocks) are made when molten material inside or outside the earth cools and becomes solid. This melted rock is called magma when it is inside the earth. When magma finds its way to the surface through cracks or volcanoes, it is called lava.When lava cools on top of the earth's surface, it forms extrusive, or …
Sedimentary rock and the processes that create it, which include weathering, erosion, and lithification, are an integral part of understanding Earth Science.This is because the majority of the Earth's surface is made up of sedimentary rocks and their common predecessor, sediments.Even though sedimentary rocks can form in drastically different ways, their …

Igneous rocks are called intrusive or plutonic when they cool and solidify beneath the surface.Because they form within the Earth, cooling occurs slowly.Such slow cooling allows time for large crystals to form, therefore, intrusive or plutonic igneous rocks have relatively large mineral crystals that are easy to see. Granite is the most common intrusive …
