1. rock 2

Explanation:

1. For Rock 1: It shows signs of physical weathering, likely from freeze-thaw cycles (water seeps into cracks, freezes and expands, splitting the rock) and possibly wind/ice abrasion in a cold, coastal environment.
2. For Rock 2: These are rounded pebbles formed by long-term water erosion—they were carried and rubbed against each other in moving water (like a river or shoreline), smoothing their rough edges and wearing them into small, rounded shapes.

Answer:

1. Rock 1: It has split apart due to physical weathering, most likely freeze-thaw action in its cold, snowy environment, where water seeped into cracks, froze, expanded, and broke the rock into large chunks.
2. Rock 2: These rocks were worn down into smooth, rounded pebbles by constant friction and tumbling in moving water (such as a river or ocean waves), which gradually stripped away rough edges and shaped them over time.
