Most volcanoes, when they finish erupting, leave a crater behind when the magma retreats down the volcanic pipe. Occasionally this will fill with water to leave a lake.
A large surface explosion will leave behind a Caldera - a broad area possibly still of geothermal activity. Such as Yellowstone, or Okataina.

Folded mountains form when rock layers are squeezed together and pushed upward. If you take a pile of paper on a table top and push on opposite edges of the pile, you will see how a folded mountain forms. They can appear crunched up together. They are ranges that are formed at a convergent boundary.
