Question

Which of the following can be an element of both mechanical and chemical weathering?


oxygen


gravity


carbon dioxide


water

Answer 1

what do you think?

Answer 2

c?

Answer 3

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).

Answer 4

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.
