Corrected sentence
Arctic foxes turn brown in the summer to blend with the rocky soil.
Step-by-step explanation
- Subject-verb agreement: The subject is plural (arctic foxes), so the verb should be "turn" (not "turns").
- Article usage: We typically include the article the before "summer" when speaking about a specific season in a sentence, but it's also common to say "in summer" without the in general statements. Either is acceptable here; we’ll keep it simple with the summer for explicitness.
- Time phrase choice: Both "in the summer" and "in summer" are correct. We used "in the summer" for clarity.
- Clarity: The overall meaning is clear: the foxes change color to blend with the environment.
Final version
