Deformation (e.g., rock fracturing, bulging, collapse) of the earth's crust happens above a buried magma chamber due to lava filling and emptying the magma chamber. Volcanos, fissures, craters, and calderas are all landforms that result from surface deformation. When the magma chamber beneath a volcano fills up, it expands like a balloon and pushes up on the ground surface. In response, the ground over the magma chamber stretches (again just like the rubber of a balloon!) and develops cracks. Imagine dipping a balloon in pancake batter prior to inflating it... would cracks develop in the batter, or would it clump up and get closer together? Imagine two people are standing facing one another, and then a wide, broad crack in the earth's surface grows between them. Imagine that crack is just like the crack shown by Kyle at 15 minutes in the video on Kilauea. Would the two people standing on either side of this crack move closer together or further apart? Hint: draw a picture to help you visualize this situation! Group of answer choices Neither, so the amount of crustal deformation is negligible Further apart, so the deformation is due to extension of the crust. Closer together
