The Perseid meteors are associated with the comet Swift-Tuttle. As the comet comes close to the sun, it starts to melt, and it leaves a trail of rocks and other debris behind.

Well, you would most likely find a rock under a tree, or perhaps in your own garden. Rocks are pretty easy to find, you just need to know the best place to find one for your area. * Woods- This is the easiest area! You probably can find a couple rocks on the trail, or some off the trail! * Country- It's pretty easy to find rocks in the country because there is often a lot of open space. * Suburbans- It's kind-of easy to find rocks in this area. Since there are some pine trees, try looking under a pine tree. * City- The city would be the hardest place to find rocks, but rocks still can be found.
