The diagram below shows the stump of a tree whose root grew into a small crack in bedrock and split the rock apart. The action of the root splitting the bedrock is an example of

• physical weathering

• chemical weathering

• mass movement

• deposition

The bedrock at a certain location is deeply scratched, and in some places is covered by a layer of unsorted sediment. Which erosional agent was probably responsible for these features?

• ocean waves

• running water

• glaciers
