I think it might be water. I mean, water can weather by both mechanical (forming rivers, or splitting rock... aka the Grand Canyon)  and chemical properties (rusting).

Okay so we can definitely cross out gravity. Oxygen can be played with to make tools, but not weather, so that's out too. I think it should be water, but why would you suggest carbon dioxide? It's the only one I'm not sure of haha.
