Final answer:
Dissolution and recrystallization can reshape a mineral crystal subjected to horizontal stresses, but the specific form it will reshape into cannot be determined based on the given information.
Step-by-step explanation:
When a mineral crystal is subjected to horizontal stresses over time, dissolution and recrystallization can reshape the crystal. The specific form that the crystal will reshape into will depend on various factors, including the mineral composition and the type of crystal lattice structure. However, based on the given information, it is not possible to determine the exact shape to which the crystal will reshape.
