Tiny ice crystals · Snow is made of many tiny ice crystals stuck together.
Frozen water · Ice is water that got very cold and turned solid.
True · Water freezes into solid ice when it gets very cold.
Hidden under the water · Only a small tip of an iceberg shows above the water. Most hides underneath.
An iceberg · A big floating chunk of ice in the ocean is an iceberg.
True · Frozen water takes up more space, so the same size piece weighs less and floats.
It floats on top · The same size piece of ice weighs less than liquid water, so it floats instead of sinking.
Icebergs are huge, and most hides underwater · Icebergs are big, and most of the ice stays hidden below the water.
