c. Tomadoes uprooting trees leaving behind the soil
d. Glaciers moving revealing bare rock underneath

Respuesta :

Answer: d. Glaciers moving revealing bare rock underneath

Explanation:

Primary succession is what happens when living things colonise an area that was previously uncolonized because it had been destroyed or hadn't been created yet.

When glaciers move on from areas and expose the bare rock underneath, these areas are new and so primary succession will take place as living things begin to colonize this new area.
