Question

Folds in rocks typically form

1. in response to tensional stresses (i.e. where rocks are being pulled apart)
2. where rocks have a brittle rheology
3. in response to compressional stresses (i.e. where rocks are being squeezed together)
4. from pyroclastic volcanic eruptions
5. where rocks are undergoing physical weathering

Answer 1

Folds in rocks typically form in response to compressional stresses, where rocks are being squeezed together. The behavior of rocks under stress depends on various factors.

Step-by-step explanation:

Folds in rocks typically form in response to compressional stresses, where rocks are being squeezed together. When rocks are subjected to increased stress and strain, they behave in an elastic manner until reaching their elastic limit, at which point plastic deformation commences.

The resulting deformation depends on factors such as the type of stress, type of rock, and pressure and temperature conditions.
