Since there isn't suggested answers I'll answer you which are not found.
In mid latitude regions of the Earth the climate types that are lacking are the tropical climate types, and the polar climate types. The tropical climate types are concentrated around the Equator and in lower latitudes, while the polar climate types are concentrated around the poles and higher latitudes.
They are changing the landscape forms through erosion.
the resulting landforms include glacial cirques, striations, glacial horns, trim lines, U - shaped valleys, sheepback (roches moutonnees), overdeepening (basins or valley were the water can be accumulated) etc
