Dear Sai,
Here is the answer to your question :

Canyon - Erosion
Moraine - Deposition
Lagoon - Neither formed by erosion nor by deposition. It is a shallow body of water which is formed after being separated from the main water body by islands, reefs or shoals etc.
Barchan - Erosion
Sea Arch - Erosion
Cirque - Erosion
Ox bow lake - Erosion as well as deposition
Delta - Deposition
Sea Cliff - Erosion
Loess - Deposition
Natural levees - Deposition
Rock Pedestal - Erosion

Hope this helps.
