Answer 1

A. Uplift raised the level of a piece of crust
C. Mountains eroded
E. Basaltic lava flowed from cracks in the crust

Answer 2

Answer:

Options (A), (C) and (E)

Explanation:

The plateaus are defined as the highland areas where the top of the plateaus are relatively horizontal. This is probably due to the effect of erosion. These are located at a higher elevated region with respect to the surrounding areas and forms over the continental crusts.

These plateaus are mainly formed when hot intruding magma cools due to the lowering of temperature and thereby crystallizes. This generally forms when two plates collides at a relatively slower rate, and in the hotspot regions. It also occurs due to the eruption of basaltic lava through the elongated cracks and fissures of the volcanoes, as a result of which large and extensive basaltic type of lava sheets are generated.

Thus, the correct answer is options (A), (C) and (E).
