Describe a stock

What is tension?
pulling something apart
Why do some igneous rocks come out rough?
they cool down slower
What is elastic deformation?

Describe a sill
magma that "jumps" between parallel rock layers
the "failing" or breaking of rocks on a fault line causes what?
an earthquake
What is shearing?
