Gases and Pressure

Most of you know I'm a wildflower fanatic. I love my plants. But now I'm learning, gradually, about the geology of the Cascades and volcanism. I won't go into the whole lecture here. The question for yesterday was, "How do you teach kids about pressure build-up inside the earth?" By trying to squeeze 10 kids into a circle made by 5 other kids! Duh.

The build-up of gases under the surface of the earth contributes to the explosive forces of some volcanoes...
