Скачать или смотреть The Rock Cycle Explained | Igneous, Sedimentary & Metamorphic Rocks

In this Earth science lecture, we explore rocks and the rock cycle, including how igneous, sedimentary, and metamorphic rocks form and how to identify them. You’ll learn the differences between magma and lava, intrusive vs. extrusive igneous rocks, and how weathering, erosion, heat, and pressure drive the rock cycle.

This video also covers:
How igneous rocks form and how to identify felsic, intermediate, mafic, and ultramafic rocks
Common igneous rocks like granite, basalt, obsidian, pumice, and scoria
Sedimentary rocks, including detrital, chemical, biochemical, and organic types
How to identify conglomerate, breccia, sandstone, shale, limestone, chert, and coal
Metamorphic rocks, including foliated vs. non-foliated textures
Rock transformations such as shale → slate → schist → gneiss and limestone → marble
A clear explanation of Bowen’s Reaction Series and why some rocks are darker than others

This lesson is ideal for high school Earth science, college geology students, and anyone learning geology basics.
