Which landform results from the deposition of materials in a valley during volcanic eruptions?

sill

mud pot

caldera

lava plateau

The correct answer is "lava plateau".

Explanation:

Lava plateau is a landform that is formed from the deposition of materials after many successive volcanic eruptions. These landforms are formed particularly after many quiet explosions, which produce very fluid lava. Pyroclastic plateaus is very similar to lava plateau, with the difference that they are comprised of pyroclastic rocks, which have agglomerates, tephra, and volcanic ashes.
