the photograph shows a plateau in canada.
what is one way a plateau can form?
a. tectonic movements make folds and faults in the crust.
b. magma rises at a divergent plate boundary.
c. continental plates slip past each other at a transform boundary.
d. uplift raises the level of a piece of crust.

Explanation:

• A plateau is a flat - topped highland. Uplift (a vertical elevation of the Earth's crust) can raise a piece of crust. If the crust is raised uniformly (without significant folding or faulting in a way that would disrupt the flatness too much), it can form a plateau.
• Option A: Tectonic movements making folds and faults in the crust are more associated with mountain - building (e.g., fold mountains) rather than the formation of plateaus.
• Option B: Magma rising at a divergent plate boundary is related to seafloor spreading and the formation of mid - ocean ridges (in oceanic - oceanic divergent boundaries) or new oceanic crust. It is not a typical way for plateaus to form.
• Option C: Continental plates slipping past each other at a transform boundary is associated with earthquakes and can form fault - line valleys or other linear features, but not plateaus.

Answer:

D. Uplift raises the level of a piece of crust.
