In this lesson you will learn about drumlins, one of the major features of glacial landscapes. You’ll also take a quiz to check your understanding of the subject.
If you have a dog, you’ve probably used your detective skills to figure out what your pet has been up to all day while you’ve been at work or school. A trail of toys (or shredded paper, or even your shoes and socks) can give you clues about where your dog played, ate, and napped, as well as where she got tired of carrying a particular item and decided to leave it behind. You can play detective with geology, too. In some ways, even a powerful geological force such as a glacier is a little like an enormous puppy, and the landforms ancient glaciers left behind can tell us what they were up to all those thousands of years ago.
