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.
1 Having a flat fixed by a tire or repair shop typically costs $5-$40 for a standard tire and $30-$60 to repair a run flat tire (designed to be safe to drive on even when it is flat). If the spare tire is flat or not available, and if a temporary fix isn't possible, towing a vehicle to a shop where the flat tire can be repaired or replaced can cost $35-$125 or more, depending on location and type of vehicle.
