Igneous rock - Wikipedia
Igneous rock (igneous from Latin igneus 'fiery'), or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rocks are formed through the cooling and solidification of magma or lava .

2024年1月31日 · Let’s explores the nature of igneous rocks, their types, formation processes, properties, classification, and textures. What Are Igneous Rocks? Igneous rocks form from the solidification of molten rock material. They are categorized based on their origin, texture, and mineral composition.
What are igneous rocks? | U.S. Geological Survey - USGS.gov
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.

2023年2月17日 · The igneous rocks are one of the three main types of rock found on earth; the others are sedimentary rock and metamorphic rock. They are the hardest and heaviest rock on earth. They are also called the ‘new’ rocks or magmatic rocks.
Igneous Rocks - Definition, Characteristics, Types, Examples & Uses
Igneous rocks are defined as types of rocks that are formed when molten rock (rock liquefied by intense heat and pressure) cools to a solid state. Lava is molten rock flowing out of fissures or vents at volcanic centres (when cooled, they form rocks such as basalt, rhyolite, or obsidian).
Igneous Rocks | Pictures of Intrusive and Extrusive Rock Types
What are Igneous Rocks? Igneous rocks are formed from the solidification of molten rock material. Some form below Earth's surface. Some form on or above Earth's surface. We describe these two basic types: Intrusive igneous rocks crystallize below Earth
Igneous Rocks: Formation, Classification, Examples, Uses
Igneous rocks are rocks that formed from the cooling and solidification of magma or lava. Magma is molten rock that is below the surface of the Earth, and lava is molten rock that has reached the surface.
Igneous Rocks - Geology (U.S. National Park Service)
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 material is known as magma until it is erupted onto the surface when it then is termed lava.
Igneous Rocks | Types, Classification, Properties, Formation
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.
