Types of Stress and Faults

The lesson covers forces on Earth's crust, focusing on stress types: compression, tension, and shearing. It explains how these stresses lead to different faults: normal, reverse, and strike-slip. Visual aids help illustrate these concepts, along with folds like anticlines and synclines. The lesson concludes with a discussion on plateaus, highlighting their formation and characteristics.
