What are kettles, and how do they form? What will be an ideal response?

Question 2

What are the different types of moraines: end moraines, ground moraines, recessional moraines, lateral
  moraines, and medial moraines? What will be an ideal response?

Answer to Question 1

Kettles are circular to oval depressions, sometimes containing small lakes, found on outwash plains,
valley trains, or end moraines. They form when a block of ice, left by a retreating glacier, is partly or
wholly buried, and then melts, leaving a depression.

Answer to Question 2

Moraines are landforms composed of till. End moraines are deposited by a glacier that has been in one
position for some years. It is all the till that accumulates at the glacier's terminus at the time of its
farthest advance. Ground moraines are the till that is left on the ground as the ice front recedes.
Recessional moraines are like end moraines, but they are from locations where the ice stabilized for a
time back from its farthest advance location. Lateral moraines form along the margin of a glacier.
Medial moraines develop by the coalescence of two lateral moraines when two glaciers merge
