How are the locations of earthquakes, mountain ranges, and volcanic activity related

Earthquakes, mountain ranges, and volcanic activity generally occur together in a well defined bands in specific regions.

Studies on tectonics show that crustal activities are occurring world wide. Earthquake, volcanoes, and mountain ranges do not occur randomly. There are special zones in which they all occur.

Earthquakes occur in bands. One goes around the Pacific Ocean, another runs horizontally through Eurasia, and a third is found in the general area of the Mid-Atlantic Ridge.

The regions where earthquakes occur is also where mountain ranges and volcanoes are found.

This is all you, but i can give you some topics that you could try. if it rained when you want to do something outdoors, it 'limits' that human activity. maybe you want to do an experiment that goes throughout the whole year and you have to have above freezing the entire year. this 'limits' your activity. i thought of those just off of the top of my head. something that gets to me that might be getting to you is you are thinking too hard about what to do. think simply, and if it is too simple, then bump it up just a little bit.
