Which answer choice best describes the difference between folded mountains and fault-block mountains?
melamori03 [73]

The answer is; C

In folding, when segments of Earth's crust are bent and doubled over, the sediments in between are form folds, since they are forced into a smaller space.  This also occurs in converging plates boundaries.

Block Mountains occur when stress due to compression in the crust causes the hanging wall between a fault to move up relative to the footwall.

Julli [10]

Answer:

+/- 0.00033

Explanation:

For a 95 % confidence interval the range is given by

+/- Z * s/sqrt(n)

where Z value is 1.916 for a 95% confidence interval

Therefore the interval is

s is the standard deviation in this case 0.0015

n is 75 the number of outposts

calculating,

+/- 1.916 * 0.0015/sqrt(75) = +/- 0.00033
