A granite can be transformed from an igneous rock to a sedimentary rock and then to a metamorphic rock or the sedimentary rock can be transformed back into granite again by metamorphism. First of all, a granite often occurs in mountains and is susceptible to weathering and erosion.. Weathering such as argillic weathering can help break t he rock down to its constituent minerals which are mostly quartz, orthoclase feldspar and biotite mica. This then gets washed down into the rivers and thence to the coast and gets deposited in a marine environment as part of a delta or alluvial fan, in the form of sand, silt, clay and gravel. As this sediment becomes compacted, it turns into rocks like sandstone, siltstone etc. With deeper burial and the addition of heat and pressure these rocks get converted into such metamorphic rocks as quartzites, slates and phyllites, etc. I have seen a meta sandstone grade into a granite in the Canadian Shield so granite can then form from metamorphic processes as well as igneous processes.
The only disadvantage I could think of would be price of equipment needed to produce energy from the source (i.e. price of solar panels)
The core has the largest density, being made of iron and nickel
The mantle has an intermediate density and the crust has the lowest density.
From the box plot shown we see that:
The median of Liam's data is 10, the range is (20-4)=16
The median of Sumat's data is 14, the range is (22-3)=19
The correct answer will therefore be:
C. The range of Liam's data set is 16
