Question

Gold is found mostly in igneous or metamorphic rocks. When water acts upon these rocks, gold may be carried and distributed to streams. Which process is responsible for the distribution of gold in this case? A) a biological process B) a metamorphic process C) a sedimentary process D) human activity E) volcanic activity

Answer 1

Answer:

Option (C)

Explanation:

The magma when it comes out to the surface from the greater depth, the magma gets crystallized having the gold in it. These rocks sometimes alter into metamorphic rock due to the extreme pressure-temperature condition. These rocks are affected by the water as it flows over them and over a due course of time, it weathers and erodes the minerals and is carried to some other place. This process of erosion and deposition of minerals is known as the placer deposits.

Thus, Gold is one type of mineral that is distributed by this type of sedimentary process.

Hence, the correct answer is option (C).

Answer 2

Answer: A sedimentary process
