Question

Describe how rocks behave under different types of stress such as compression, pulling apart, and shearing​

Answer 1

Compression, pulling apart and shearing​ are all types of stress that occur in rocks.

Effect of compression on rocks

• As a result of compression, rocks are squeezed together under pressure. At convergent plate boundaries, the effect of compression on rocks can be commonly observed.

Effect of pulling apart on rocks

• Pulling apart rock causes tension in the rocks. As a result of this tension, the rocks will either lengthen or they will break.

Effect of shearing on rocks

• The type of stress which occurs in rocks when the forces are parallel but opposite is termed as shearing. This type of stress is most common in transform plate boundaries
