Metamorphic Rocks Lesson #14 Rocks are formed on Earth as igneous, sedimentary, or metamorphic rocks. Igneous rocks form when rocks are heated to the melting point which forms magma. Sedimentary rocks are formed from the cementing together of sediments, or from the compaction (squeezing together) of sediments, or from the recrystallization of new mineral grains which are larger than the original crystals.
Roadside assistance plans typically do not include any needed repairs. Having a flat tire patched can cost $0-$60, depending on type of tire. Replacing a typical car battery can cost $50-$220.
Before you head off to a repair shop to have your wheels aligned, a job that typically costs about $60 to $100 for most vehicles, it would be a good idea to check your tire pressure. Underinflated tires can also cause a vehicle to pull to one side, so eliminate that possibility first.
