A downhill
Explanation:
A runoff happens when water drags sediment from a rock over a sloping terrain. Thus, water drags the eroded fragments of a rock in favor of gravity, pushing these fragments downwards.

It is the most abundant ore of aluminum.
It is located near the surface and can be easily strip mined
Explanation:
Bauxite is the most common ore of aluminium be cause it contains the most aluminium and the ore is located near the surface.
- Bauxite is a sedimentary rock that contains about 30-55% aluminium.
- it has a very high aluminium content in it .
- Bauxite is made up of aluminium rich minerals such as diaspore, gibbsite and boehmite.
- The rock bauxite forms in tropical climate where laterite has been seriously leached and the aluminium becomes concentrated.
- Since it is a sedimentary rock, the formation can be accessed by strip mining.
- This entails the removal of the overburden and mining the ore.
- Strip mining is used for ores close to the surface.
