You're doing a nice job! Here are a couple of small tweaks to make the sentence clear and correct.
- Subject-verb agreement: The subject (walrus) is singular, so the verb should be uses or uses its as you have. Your sentence uses is fine.
- Article choice: You can say onto the ice or onto the ice surface. Both are understandable; onto the ice is perfectly good.
- Clarity: If you want to emphasize how the tusks help, you could add a tiny detail, but it’s optional. For example: A walrus uses its tusks to climb onto the ice.
Corrected sentence (optional alternatives):
- A walrus uses its tusks to climb onto the ice.
- A walrus uses its tusks to climb onto the ice surface.
