Depends. If you are very careful about handwashing (plain old soap and water are best - antibacterial soaps don't actually do anything extra), washing for a good 30 seconds at least, before eating, and after bathroom visits, you might not get it. Also depends on how careful the other person was. If they are not a careful handwasher, and made food for you, you could be getting sick in as little as 12 hours or as late as 3 days. Check out the CDC website, look up Norwalk Virus (the real name for what people typically call tummy flu) Stay well!
Marble is another example of a metamorphic rock. It is formed from limestone. Metamorphic rocks sometimes contain fossils if they were formed from a sedimentary rock, but the fossils are usually squashed out of shape. Metamorphic rocks can be formed from any other type of rock-sedimentary or igneous. Remember these two examples of common metamorhpic rocks and where they come from: slate is formed from shale. marble is formed from limestone. 1  Page. 2  1. 3  2. 4  3. 5  4. 6  5.
Lesson: Igneous rocks are formed when the magma from a volcano cools-. Sedimentary rocks form when eroded earth and other materials settle in layers. These layers press down over time to form solid rock. Metamorphic rocks are igneous or sedimentary rocks that have been changed by high temperatures or extreme pressure.
