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.

The U.S. State of Alaska used to be a part of Russia, until America bought it in 1867.
The answer is: comparing the Sun’s relative position at two different locations on the earth’s surface.
Explanation:
In the third century BCE , Eratosthenes, a Greek librarian in Alexandria , Egypt , determined the earth's circumference to be 40,250 to 45,900 kilometers (25,000 to 28,500 miles) by comparing the Sun's relative position at two different locations on the earth's surface.
Eratosthenes determined the earth's size by observing known phenomena and applying basic arithmetic and geometry to them. Here's how he did it. Eratosthenes' methods were simple but effective. All he needed to know was the distance between two locations and what percentage of a circle this distance constituted.
