Chunks do not really mean something very small like most people may think,it could be a large particle or huge mass. Floating chunks of ice from ice sheets or ice shelves (land ice) are called "ICEBERGS", while large areas of floating sea ice are called "ICE FLOES".
icebergs
A "slow moving river of ice" is a glacier. A slow moving chunk of ice floating down a river is a "floe".
Names for frozen water other than ice includeSnowHailFrostRimeA glacierA floe - (a chunk of ice floating in the sea).
Fail ice floe is another possibility.
IcebergI believe they are called icebergs... The process is called calving though
GlacierLarge masses of floating ice are called Icebergs. There are different types, but that is the general term applied to those large masses of ice.
Ice bergs.
A lage chunk of ice floating in the water, most of it is in the water.
Icebergs change size and shape constantly. When a fissure or crack develops and a portion breaks off it is called a floe. Changes in icebergs are determined by climate, pressure, force and temperature.

Floating ice is already in the water, so its melting causes no rise in lake levels.

You are probably thinking of an Iceberg, which can be a very large piece of floating ice.

A chunk of ice will float higher in water than an ice cube only if the ice chunk is larger than the ice cube.
