Which is likely to change the shape of a landform?
a) glaciers
b) lunar phases
c) solar radiation
d) gravitational pull

Glaciers change the shape of the landform with its gradual movement.

Explanation:

Glaciers result in landforms when the ice erodes the surface and carries broken rocks and soil remains. They can drastically reshape the landscapes.  Lunar phases will not affect the shape of a landform. The moon’s rotation is locked by Earth’s gravitational force. The phases of moon change over a month. Solar radiation reaching the earth’s surface is the surface solar radiation which is responsible for the surface energy balance. Gravitational pull also effects landforms by pulling water and ice downhill. This can cause erosion in an indirect and direct ways. It can pull the soil, land, rocks, cliffs etc. But glaciers prove the most effective ways in affecting landforms.
