Answer:
Step-by-step explanation:
It seems like you've described two types of rocks based on their appearance. Here are the likely rock types that correspond to your descriptions:
1. **Orange rocks with evidence of erosion:** These rocks could be sedimentary rocks. Sedimentary rocks often come in various colors and can show evidence of erosion and sedimentation, which contributes to their appearance.
2. **Molten material at the surface cooling into black swirled formations:** This description matches **igneous rocks**, specifically those formed from molten material. The black swirled formations are likely indicative of a specific type of igneous rock, possibly a **basaltic** rock, which commonly forms from lava cooling rapidly at the surface.
