Exploring Stress and Deformation in Earth's Crust

The video explores how Earth's landscape is shaped by stress, leading to earthquakes and fault formations. It explains stress as a force that deforms rocks, detailing elastic, ductile, and brittle deformation. The video also covers different fault types and tectonic plate boundaries, emphasizing the role of stress in shaping Earth's features.

What is the primary cause of deformation in Earth's crust?

• Gravitational pull from the moon

• Volcanic activity

• Stress from tectonic forces

• Erosion from water
