Choices:1. seas and oceans 2.moutains 3.hills 4.plateaus 5. plains

Seas and oceans for B

Mountains for D

Plateau for C

Hills for F

Plains for A

Explanation:

In "b" it says fishing and shipping which would be a major giveaway tht the answer is sea and oceans as fishes live in oceans and ships go on water:)

In "D" it says "natural barriers". Throughout history, mountains have been the #1 natural barrier and protector against enemies.

for C it says scarce rainfalls. Plateaus are desert like and have little to no rainfalls

for A it says fertile soil, good for life. If you ever look at a pic of a plain u would;d see how green and healthy they are. Plains get a lot of rainfall and are amazing for sustaining human and animal life.

"F" was done by using process of elimination :)

heat from the core of the earth causes convection currents to occur in the mantle. these currents slowly move the crust around.
