Air enters the rock cracks?
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).
How does ice forms in a rock and makes it split?
Physical weathering
What are the main causes of crack growth in rocks overtime?
weathering and plant growth growing through and eventually causing a crack in the rock
How can ice cause weathering in rocks?
Yes. Ice causes physical weathering by gring rock with abrasion or by freezing and thawing when ice is stuck in rock it expands putting a larger crack in the rock and when it thawes the water goes down the rock and erodes it.
What kind of weathering causes repeated expanding due to the heat and contracting due to cold strains the rocks and causes them to crack?
Thermal expansion causes repeated expansion and contraction within the rock. This repeated stress breaks bonds and eventually causes the rock to crack. Thermal expansion is classified as a type of physical or mechanical weathering.
What causes rock to split?
Rock splits due to pressure of the Earth's tectonic plates, which causes the rock to crack, fracture and separate. This process is known as fracturing.
Does Freezing makes a rock crack?
No
What will happen to a rock on the side of a mountain that has a small crack in it when rainwater continues to get into the crack every winter freeze?
The rock will split in two pieces
What causes a rock to split?
Temperatures such as freezing and thawing water causes the rock to split. Also, if something causes it to shift position and fall on another rock, it may break up.
What effect can a seed have on rock?
A seed that falls into a crack in a rock can help to expand or even split the rock. The resulting plant can gradually expand within the crack and attract moisture that will stress the rock with freeze and thaw cycles.

What causes cracks in a rock to get bigger?
Weathering, specifically freeze-thaw weathering. If rain gets into the crack and freezes, it expands and pushes the crack wider.
