The two correct answers that indicate that different rocks in the same area might weather differently are:
- Cliffs with ridges - This suggests variations in rock type or structure that can lead to different weathering rates.
- Rock pillars in the middle of grassy plains - These can indicate that certain types of rock withstand weathering better than others around them, leading to differences in how they weather.
The other options (rock deep in a cavern and a smooth plain) do not strongly suggest variations in weathering based on rock type or exposure.
