Cliffs can be composed of various types of rocks, including limestone, sandstone, granite, and basalt. The type of rock that makes up a cliff depends on the geology of the area in which it is located.
Any form of mechanical weathering causes rock to break into smaller pieces. A landslide will definitely cause rock to break. Meteor impact, plant root growth, ice wedging, and the movement of animals will also cause weathering.
You might see a similar type of weathering in nature on coastal cliffs where the combination of wind, water, and salt spray gradually erodes the rock surface. Additionally, you could observe similar weathering processes in arid environments where extreme temperature fluctuations cause rocks to expand and contract, leading to cracking and breakdown.
I live in a sandstone-rich area of Scotland and my house in fact is built of sandstone, as are several walls near it. There is also a sandstone quarry outside the town. It is basically a 'stone' (if you could call it that) which is made of sand, crushed together thousands of years ago. If you scrape it, sand comes off. If I wanted i could scrape my way into my house with a spoon. Throw a sandstone block on the ground and it will split into several pieces easily. Cracks do not usually stay in a sandstone block due to its nature - a crack will normally just split the block in 2. So to answer your question, sandstone CAN have cracks, but not big ones or it will just shatter into bits. Basically, no.
Water has the unusal property of expanding, when frozen into ice. Water that seeps into cracks and then freezes, exerts tremendous pressure, which forces the crack open. During a thaw the loose parts will fall out.
Not in the usual sense. Jupiter is composed of gas, not solid land, although there is some thought that the very center of Jupiter could be composed of iron or a similar element.
smoking too much crack
An undersea earthquake causing a large displacement of the sea floor can cause a tsunamis. Another cause could be when a large area of cliffs suddenly crashes into the sea, so setting off a displacement of the sea.
The cliffs overlook the sea
A car can idle too low because there is a leak in the vacuum. Cracks or breaks on the vacuum hoses in the cars engine could be the cause of this.
It could be an emergent coast.

You could be very dehydrated or have a special disease. I would suggest drinking a lot of water unless it hurts.
cracked head or a cracked block cracks may be hard to see with the naked eye
You've got a short somewhere. Check closely at all wires for cracks/breaks where they could be touching metal.
