The difference between these three types of rock is in their formation process:
• Igneous rocks are formed by thesolidification of melted rocksm(agma) inside the Earth.
,
• Metamorphic rocks are formed from the other types of rock that suffer changes due to different processes,for examples caused by high preasures or heat.
,
• Sedimentary rocks are formed by the accumulation
One useful point about the moment magnitude scale is that it is logarithmic, where each whole number represents a factor of 32. Therefore, the difference in two whole numbers of the magnitude means that an earthquake is 1,000 times stronger. For example, a 7.0 magnitude earthquake releases 1,000 times more energy than a 5.0 one.
