The majority of cracks in concrete foundations are a result of shrinkage in the concrete. Shrinkage is a normal occurence and should not be a cause of great concern. Fixing cracks yourself can be done through a process called low presssure crack injection. Urethane is forced into the crack sealing the crack all the way through the wall. The process takes about one hour and a typical kit costs about $100. DIY kits can be purchased at www.thebasementoasis.com or contractor can be found through contacting www.cmemanufacturing.com.
broken underground water pipes cause cracks when gone un-noticed due to water sucked into the concrete--water freezing and then spreading the concrete molecules apart
Tree roots also cause foundation cracks when large trees are planted too close to the house or vice versa.
there is also the shifting of land and the settling of a newly built home that goes un-detected as time passes by.
Ground settling.
It is not a good idea to cover foundation cracks with gardening. Have a knowledgeable building expert check the foundation crack and repair it. Don't hide it with plants and invite water to leak into your house.
Subsidence (movement) of the foundation. Most newly built buildings will tend to settle, which is natural and is expected. But, if the settling goes too far, or earthquake tremors disturb the subsoil, then cracks may appear to show stress.
Horizontal cracks in foundation walls are typically more serious than vertical cracks because they can indicate excessive pressure from the soil and may compromise the structural integrity of the foundation. Vertical cracks are more common and can be caused by normal settlement or minor shifting of the foundation. It's important to have a professional assess any cracks in your foundation to determine the severity and appropriate repair solution.
The Sidney Crosby Foundation does exist. Yeah but it is really shaky....and it has a lot of cracks in it
If the foundation problems are not covered then it naturally follows that any resulting cracks would also not be covered.
Carbon Monoxide
This can sometimes happen when water finds a way into cracks, which then freezes, expands, and this process repeats, making cracks.
yes and no if it is like a foundation it could be because your foundation is settleing and is gettin uneven and can continue to crack

Frost heaves.
I'm assuming you mean vertically (The ceiling appears to moving up). Your house could be heaving or settling. You should check your foundation for cracks. You may have a huge problem.
