Question 1 of 10
10.0/ 10.0 Points
Which of the following mining processes removes the top layers of soil, rock, and vegetation to
access minerals?
A. Acid mine drainage
B. Subsurface mining
C. Smelting
D. Surface mining
Answer Key: D
Feedback: Surface mining removes surface vegetation, rocks, and soil to create an open pit for
mining. Subsurface mining uses vertical or sloping shafts to access minerals deep underground.
Smelting melts ore to separate valuable minerals from impurities. Acid mine drainage occurs
when acidic pollution from mining drains into nearby water sources. Source: Lesson 5,

C. Soil salinization
D. Soil erosion
Answer Key: C
Feedback: Soil salinization occurs when repeated irrigation and poor drainage increase the
salinity of the soil. Soil erosion occurs when wind or rain remove soil from the land.
Desertification occurs when wind and drought cause ecosystems to become barren deserts.
Contour plowing helps conserve soil by plowing along the natural contours of the land. Source:
