They may be formed simply by being deep beneath the Earth's surface, subjected to high temperatures and the great pressure of the rock layers above it. ... Some examples of metamorphic rocks are gneiss, slate, marble, schist, and quartzite.
The correct option is B. Normal fault is produced by tension when a block of rock dropped down in relation to the block of rock beside its thrust fault is produced by compression.
The normal fault, where one rock block lowers down in relation to the other, the strike-slip fault, where the fault blocks slide past one another horizontally, and the reverse fault, where one fault block slides upward in relation to the other, are the three major types of faults.
<h3>
What are a normal fault and a reverse fault?</h3>
Normal faults are caused when two plates that are stacked one on top of the other slip past one another. One plate sliding under the other results in a vertical offset, which causes reverse faults. When two plates pass each other horizontally, strike-slip faults occur.
Grabens descend in relation to neighboring blocks, forming valleys. Horsts become areas of higher topography as compared to nearby blocks that have been down-dropped.

Answer:
There are four major issues affecting the oilsands: declining price outlooks, market access, a reduction in investment and climate change pressures.
Explanation:
The environmental consequences of oil production from Alberta's tar sands are major, beginning with its effect on climate change. North America's transition to oil from the tar sands not only perpetuates, but actually worsens, emissions of greenhouse gas pollution from oil consumption.
C is the answer, because the mantle is made up of liquids and liquids are less dense than solids
