KIDS TRIVIA

Detailed explanation-1: -How do ice shelves form? Ice shelves form in areas where cold ocean water lies next to a large continental glacier or ice sheet that reaches the sea. Under cooling or cold conditions, the ice that reaches the sea will flow out over the ocean, floating as a thick ice plate on top of it.

Detailed explanation-2: -Cirques are where ice begins to accumulate in a glacier. Two glacial cirques may form back to back and erode their backwalls until only a narrow ridge, called an arête is left.

Detailed explanation-3: -Icebergs are large chunks of ice that break off from glaciers. This process is called calving. Icebergs float in the ocean, but are made of frozen freshwater, not saltwater.

Detailed explanation-4: -An iceberg is a piece of freshwater ice that has detached from a glacier and is floating in the ocean (Figure 1). Icebergs form when pieces of ice break off the end of an ice shelf or a glacier that flows into a body of water (Figure 2).
