What factors are involved for a rock to behave as a brittle substance, and what factors cause it to
behave plastically? What will be an ideal response?
Some rocks are more likely to behave as a brittle substance, and others are more likely to behave
plastically. A small stress applied over a long period is more likely to cause plastic deformation then a
large stress applied rapidly. A rock is more likely to behave plastically under higher temperature and
pressure conditions, such as in the mantle, than it is at lower temperature and temperature such as in
the crust.
