Ques:Answer the following question given this paragraph: The amount of stress on a rock may be greater than the rock's strength. In that case, the rock will change and deform ( Figure below ). Deep within the Earth, the pressure is very great. A rock behaves like a stretched rubber band. When the stress stops, the rock goes back to its original shape. If more stress is applied to the rock, it bends and flows. It does not return to its original shape. Near the surface, if the stress continues, the rock will fracture and break. Q: What is applied to a rock to make it bend and flow? Choices: - phosphorus - weathering - acid - stress A:

Ans:stress
