Geography - Formation of a drumlin?Watch
It is thought that they are formed by a glacier which started retreating, and so formed a morain, and then began advancing again, over the top of the morain, erroding it down to the teardrop shape.
isnt morraine just like particles of rock and dirt and stuff, doesnt actually cause a drumlin 2 form.
PLEASE! Sum1 must know!!!
They are deposited due to friction between the ice and the underlying geology, causing the glacier to drop its load. As the glacier continues to advance it streamlines the mounds into a "basket of eggs" topography. these features can be used to determine the direction of glacier movement - the pointed end of the "eggs" shows the way the glacier was advancing.
You're on the ball.
