Great horned owls' wings take a longer time to develop. Therefore a baby chick usually will fly ten days later than the other owls. All in all, owls are made well. Although there are many rocks in theU.S.A., the limestone is the most interesting one of them all. First, limestone is a strong rock.
People can build houses out of it.
Secondly, limestone is made up of many different minerals. The most prominent is calcite. The calcite is a type of mineral that makes the different colors of the limestone. The colors of the limestone can be gray, yellow, white, and brown. Last, the most interesting thing about the calcite is that it is made with calcium that can hardly grow without water, so basically, limestone is from the ocean.
