Iceberg
Context
A large floating mass of ice detached from a glacier or ice sheet and carried out to sea
Explanation
Icebergs are large pieces of freshwater ice that have broken off from glaciers or ice shelves and float in open water. They vary greatly in size and shape and can pose hazards to navigation.
Applications
The iceberg towered above the water, with much of its mass submerged.
The Titanic famously sank after colliding with an iceberg.
Scientists study icebergs to understand climate change and ocean currents.
