Alpine glaciers can be found on which one of the following landforms?
a. mountain bases
b. lowland hills
c. mountain valleys
d. flat plains

The Alpine Glaciers can be found in Mountain Valleys - the correct answer is c). They then shape these Valleys, as they slowly travel through the valleys and transport material with them - making the valleys deeper and broader.
This can be seen in the specific shape that can be found in the valleys after the glaciers have melted.

Since wxyz is 4, halfof that would be 2.
