Question

in which two places is aggregate generally found?
○ floodplains and alluvial fans
○ alluvial fans and mines
○ mines and beneath the topsoil
○ beneath the topsoil and above the topsoil

Explanation:

Aggregate is commonly found in flood - plains and alluvial fans. Flood - plains are areas of flat land next to rivers that are often covered in sediment, and alluvial fans are fan - shaped deposits of sediment at the base of mountains. Mines may extract aggregate but are not natural places where it is generally found in the sense of its natural occurrence. The options about topsoil are not typical natural locations for aggregate compared to floodplains and alluvial fans.

Answer:

A. floodplains and alluvial fans
