Question

the picture shows a landform made of granite rock. the rock has many cracks that rain can get trapped in. a piece of this granite rock fell off what is the likely cause of the granite falling off the landform? choose the correct answer. acid rain dissolving rock oxygen reacting with rock freeze - thaw spreading cracks in rock

Explanation:

1. Analyze "acid rain dissolving rock": Acid rain mainly chemically weathers rocks (like limestone) via reactions, but granite is resistant to acid dissolution, so this is unlikely.
2. Analyze "oxygen reacting with rock": Oxygen - rock reactions (oxidation) are slow and more about chemical alteration over time, not sudden rock fall from cracks with rain.
3. Analyze "freeze - thaw spreading cracks in rock": Rain gets trapped in granite cracks. When water freezes, it expands, widening cracks. Thawing repeats, spreading cracks until the rock piece falls. This matches physical weathering of granite with cracks and rain.

Answer:

freeze - thaw spreading cracks in rock
