Answer 1

26. A cover of vegetation always strengthens a slope. All other options help in weakening the slope.

So option B is correct.

27. Freeze-thaw cycles result in frost wedging.

So option C is correct.

28. Stratovolcanoes are large, potentially explosive, cone-shaped volcanoes composed of alternating layers of ash and lava.

So option A is correct.

29. Nonfoliated metamorphic rocks have little or no structured grain pattern.

So option A is correct.
