Erosion and deposition constantly change Earth’s surface. Erosion carries natural materials like rock and soil from one place to another. Through deposition, these natural materials may be deposited in areas where they build up over time. Which landform results from the deposition of materials in a valley during volcanic eruptions?

a. sill

b. mud pot

c. caldera

d. lava plateau

The answer IS NOT SILL! The answer is D, lava plateau.

Explanation:

Lava plateaus are extensive areas of low-viscosity lava that cover large amounts of land. A plateau is an area of high, level ground, so lava plateaus result when lava flows and fills in valleys and rivers. Also, this screenshot of my test Edge 2020:

sediment layers stop spreading when they reach a barrier or they run out of sedimentary material. lateral spreading is the movement of gently to steeply sloping, saturated soil deposits caused by earthquake-induced liquefaction. i hope this . : )
