Question

which weathering agent is most likely to carry large boulders long distances over long periods of time?
a ice
b water
c wind
d gravity

Explanation:

Ice, in the form of glaciers, can carry large boulders over long distances over long periods. Glaciers move slowly and can transport huge rocks. Water (like rivers) can carry some rocks but usually not as large as those carried by glaciers over such long - term and long - distance scenarios. Wind mainly carries small particles. Gravity causes downward movement but not long - distance horizontal transport of large boulders like ice (glaciers) does.

Answer:

A. Ice
