Question

question 2 (0.83 points)
mass wasting over time moves earthly materials towards a lower elevation. which of
the following most likely caused the elevated height of mountainous landforms in the
first place?
tectonic uplift
chemical weathering
tectonic subsidence
none of the above
plant growth
question 3 (0.83 points)
which combination is the most likely to result in slope failure?
the shear strength is great and the force of gravity is weak
the shear strength is stronger than the shear force
the shear strength is larger than the normal force
the shear strength is weaker than the force of gravity
the shear strength is weaker than the shear force

Explanation:

For Question 2: Tectonic uplift refers to the upward movement of Earth's crust, which builds elevated landforms like mountains. Chemical weathering breaks down rock, tectonic subsidence lowers crust elevation, and plant growth does not create large-scale mountain height.
For Question 3: Slope failure occurs when the force driving movement (shear force) exceeds the material's ability to resist that movement (shear strength). Gravity contributes to shear force, but the direct comparison is between shear strength and shear force.

Answer:

Question 2: Tectonic uplift
Question 3: The shear strength is weaker than the shear force
