Magma: Definition & Formation

1. Magma: Definition & Formation

Magma is molten rock found below the earth's surface. The temperature at which a rock melts is affected by its composition, pressure and water. Learn how magma forms and how it either feeds volcanoes or cools and crystallizes into igneous rock.

Volcanic vs Plutonic Igneous Rocks: Definition and Differences

2. Volcanic vs Plutonic Igneous Rocks: Definition and Differences

Volcanic and plutonic rocks are types of igneous rock. Volcanic rocks form when lava cools and solidifies on Earth, and plutonic rocks form when magma cools and solidifies below Earth. Learn about different characteristics of these igneous rocks.

Bowen's Reaction Series: Crystallization Process & Magmatic Differentiation

3. Bowen's Reaction Series: Crystallization Process & Magmatic Differentiation

Bowen's reaction series and magmatic differentiation are two ways of explaining how igneous rocks form. Learn about the continuous and discontinuous series of the Bowen's reaction series and how magmatic differentiation works in this video lesson.

Classification of Igneous Rocks: Textures and Composition

4. Classification of Igneous Rocks: Textures and Composition

Igneous rocks can be classified by their texture and composition. Learn how texture is influenced by the cooling rate of magma and how different mineral compositions lead to different igneous rock classifications in this video lesson.

Locating Igneous Rocks: The Relationship Between Igneous Rocks & Tectonic Plates

5. Locating Igneous Rocks: The Relationship Between Igneous Rocks & Tectonic Plates

Igneous rock can form where tectonic plates diverge or converge. Learn how the movement of tectonic plates can create the right conditions of the solidification of magma and the formation of igneous rocks.

Andesite: Definition, Composition & Uses

6. Andesite: Definition, Composition & Uses

Learn about andesite, an extrusive igneous rock that forms as a result of volcanic activity. Andesite is fine-grained and intermediate in color and chemistry. It has some uses in the construction industry.
