Answer:
1. Material that settles to the bottom of a liquid; lees. 2. Solid fragments of inorganic or organic material that come from the weathering of rock and are carried and deposited by wind, water, or ice. [Latin sedimentum, act of settling, from sedēre, to sit, settle; see sed- in Indo-European roots.]
2.When granite is subjected to intense heat and pressure, it changes into a metamorphic rock called gneiss. Slate is another common metamorphic rock that forms from shale.
3.Both factors, Heat and Pressure, work together underneath Earth's surface to morph rocks from one type to another. This is generally known as Metamorphism, and most likely result in a Metamorphic Rock being produced.
4.If you consider it as one mineral, feldspar is the most common mineral on earth, and quartz is the second most common. This is especially true when you consider the whole crust (continental plus oceanic).
