Yes, air will enter rock cracks. But, if water fills the crack, during a deep freeze, the expansion of the water, as ice forms, will often widen the crack (even to split the rock).
Indirectly, yes. Rocks in areas that regularly experience below-freezing temperatures are subject to frost shattering. In this process water enters cracks, freezes, and expands, forcing the cracks open wider. This can weaken a rock structure to the point of failure.
It cracks the rock
Cross cutting relationships define rock formations in geology. When magma enters cracks and crevices in existing rocks and cools it forms what is called an igneous intrusion. The principal of cross cutting relationships means that the igneous intrusion is always younger than the rock it cuts across.
well
Water goes in a cracks. When it gets cold it thaws and freezes. It also turns into a crystal form. Then it takes a lot of space and cracks a rock.

Cryoseisms are caused by cracking actions in frozen rock or soil. Water enters the rock, freezes and expands The expansion builds up until the rock cracks
The rock cracks and weathers.
Water can do this if it freezes
places where groundwater bubbles or flows out of cracks in the rock is called springs.

the plants roots sink into the rock and cracks the rock.

Water gets into cracks in the rock, the rock cracks, turns to ice and expands so the rock splits into smaller pieces.. =]
It cracks the rock
If it doesn't have cracks in it it can still be weathered. Wind, water, hot, and cold can make the rock chip away.
