Because once they are all gone we will not get them back for several millions of years or we may never get them back
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 idea of time zones is to have a particular time of day have the same meaning worldwide. For example, noon will be the point in time when the sun is the highest, if you compare from exactly on one line of a longitude line that is used to determine the time zone (actual time zone lines change based on settlements and politics, so use the longitude line it is based on).
<span>The sun rises and sets based on the earth's rotation on its axis. Time zones divide the earth into 24 areas that will be rotated into. Latitude lines have nothing to do with the time of day or the earth's rotation--they tell you where something is north and south rather than east and west.</span>
The answer is faults because when divergent boundaries occur, the tectonic plates move away from each other, therefor creating a fault in the earths crust.
The capital of Chile is Santiago. "True."
