Understanding Compression and Tension in Geology

The video tutorial explains the concepts of compression and tension in geology, focusing on how these forms of stress affect rock layers. Compression occurs when an object is squeezed, often leading to mountain formation at convergent boundaries. Tension, on the other hand, happens when forces stretch an object, typically occurring at divergent boundaries like mid-ocean ridges. The video uses simple examples, such as spaghetti and graham crackers, to illustrate these concepts. It concludes with a reminder about the importance of kindness.

What geological features are formed by compression and tension?

• Volcanoes and geysers

• Rivers and lakes

• Mountains and mid-ocean trenches

• Deserts and plateaus

What is stress in the context of geology?

• The amount of water in a rock

• The temperature of a rock

• The amount of force per unit area on a material

• The color of a rock

What happens to spaghetti when too much force is applied?

• It bends slightly

• It becomes softer

• It changes color

• It breaks

What type of boundary is associated with compression?

• Subduction zone

• Divergent boundary

• Convergent boundary

• Transform boundary

What geological feature is commonly formed at a convergent boundary?

• Mountain

• Valley

• Canyon

• Mid-ocean ridge

What is tension in geological terms?

• A force that stretches an object

• A force that heats an object

• A force that cools an object

• A force that compresses an object

At which type of boundary does tension occur?

• Subduction zone

• Divergent boundary

• Transform boundary

• Convergent boundary
