Especially in the form of Natural Disasters, but it also gives trees, tall grass and flowers the ability to grow, water to erode and lava to smelt the ground. All these elements will over time change the Minecraft world you survive in. There are currently 4 disasters in the mod: Volcanoes, Meteorites, Sinkholes and Earthquakes.

This is the crash site of a fallen meteorite, the smoke produced from the meteor falling to the ground. You can find the meteor underground from such an impact, and it might contain some very valuable resources!
This is the beginning of an earthquake taking form. It will dig down very deep, kind of like a ravine.
This is the result of the earthquake. It is a very very long gap in the ground, and sometimes even small fractures are created.
