Explanation:The rock cycle is a model that describes how rocks are created, changed, and broken down. There are three major types of rock: igneous rock, metamorphic rock, and sedimentary rock. During the rock cycle, each type of rock may be changed into another type.
The rock cycle includes these processes:
Crystallization is the process by which magma cools and forms solid igneous rock.
Heat and pressure can change igneous rock and sedimentary rock into metamorphic rock.
Weathering and erosion are the processes that break down rock into sediment and transport this sediment to other places.
Sediment is changed into sedimentary rock by compaction and cementation.
Melting is the process that transforms solid rock back into liquid magma.
Compact fluorescent bulbs are a more efficient way to provide electrical light within homes and other buildings. These bulbs are one of the easiest ways to save money. According to GE, compact flourescent bulbs, or CFLs for short, use 70% less energy than a traditional, incandescent bulb and last up to 10 times longer than a standard incandescent bulb. As society pushes for improved efficiency, compact flourescent bulbs need to be carefully examined. Although these bulbs are more efficient, there are many problems with compact fluorescent bulbs.
