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.
All-terrain SUV or light-truck tires for moderate winter climates or for both off-road and on-road driving can cost $110-$750 or more, but average about $150-$250 each; they have a less-car-like ride and shorter tread life (many carry no treadwear warranty), and typically fit 15-20 wheels.
