Finding different kinds of rocks - a geology project answers questions

Identifying rocks

granite stairs
Queens Borough Public Library

To see the different kinds of rocks for yourself, take a walk around your town. Can you find examples of granite, limestone, slate, and marble on the buildings downtown? Can you find travertine? (this one might be more difficult).

Can you figure out why the architects chose each type of rock? Why use granite for stairs and not marble? Why is limestone a better choice for big blocks of stone than slate is?
