What will happen to a rock if rainwater freezes in a crack in it year after year?
The crack get bigger and bigger
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.
Why does heating and cooling rocks make them break more easily?
You mean FORM, correct? Well, when water (in a small crack [hairline] in a rock) turns to ice, it EXPANDS. Having no place to go, it pushes crack's sides apart thus enlarging it. Consequently, larger crack is created, eventually rock may split.
How can a rock be split apart?
If it has a small crack in it then gets water in the crack then the water freezes in the crack then the crack gets bigger and bigger until it completely cracks, or use a sledge hammer. Drive dry wooden wedges into the cracks and then soak them. As the wood expands it applies immense pressure to the rock and splits it. Driving wedges into natural cracks does not necessarily give a clean straight split of the rock. A method of splitting rock straight is to hammer a narrow chisel into the rock, rotating the chisel after every strike, making a line of deep holes. Two long semicircular pieces of metal are then put into each of the the holes and a metal wedge knocked in between them. By knocking the wedges in turn the rock splits along the line of the holes.
Is ice freezing in a crack of a rock considered weathering or erosion?
Ice freezing in a crack of a rock is considered weathering.

How do you make knuckles smaller?
You can't. They get bigger as you crack them. Don't crack your knuckles or you'll resort to big knuckles!

What is the effect on rocks in cold weather?
If it is cold, say, in Alaska, the most common effect on rocks is frost wedging. Frost wedging is when water gets in a crack in the rock, and the water freezes, making the rock crack a little more. When water keeps on going into the crack, and the ice gets bigger, it eventually will separate the rock into two or more parts, making the rock into many little rocks. I hope you find this useful! ^-^
Explain how rock openings help weathering?
Openings in rocks allow for the wind and weater to get inside and erode the surface. In areas where the temperatures get below freezing, when water gets inside a crack of a rock it freezes and when it freezes it expands. It exerts so much force when it expands that it cracks the rock further, making the crack larger and deeper which lets in more water which, well you know how it goes from there. It just gets bigger and bigger until the rock splits apart.
What does metamorphic means?
pieces of rock that have been broken down by water getting into a crack and freezing up, this will create a bigger gap and break it up to the smallest size possible.
What is a crack in the rock at a plate boundary called?
If there is movement of rock along this crack, then it is called a fault.
Is a rock considered odorless?
not if it is a crack rock
