Rocks and Earth Materials Questions
How can gabbro quarrying impact the visual landscape?
-
By creating unsightly scars on the land
-
By blocking views of natural features
-
By increasing light pollution
-
All of the above
D
Correct answer
Explanation
Gabbro quarrying can impact the visual landscape in a number of ways. The quarrying process itself can create unsightly scars on the land, while the presence of quarrying equipment and infrastructure can block views of natural features. Additionally, quarrying operations can generate light pollution, which can disrupt the natural night sky.
