Iceberg Characteristics and Effects

The video explores the concept of 'tip of the iceberg,' explaining that most of an iceberg is submerged due to the density difference between ice and seawater. It details the formation of icebergs from glaciers, their lifecycle, and the unique sounds they make, such as Bergie Seltzer. The video also covers iceberg size classifications, colors, and movement patterns, highlighting their role as mobile ecosystems that support diverse marine life. Despite their remote origins, icebergs can travel vast distances, impacting oceanic environments and shipping lanes.

Why is only a small part of an iceberg visible above water?

• Because icebergs are hollow inside

• Due to the density of pure ice being less than seawater

• Because icebergs are mostly made of air

• Due to the reflection of sunlight

What is the primary force that moves glaciers towards the sea?

• Tidal waves

• Gravity

• Wind

• Ocean currents

What sound is produced when an iceberg melts?

• Ice Crackle

• Glacial Roar

• Bergie Seltzer

• Frozen Whisper

What is the smallest classification of an iceberg called?

• Growler

• Ice Chip

• Bergy Bit

• Mini Berg

What gives some icebergs their blue color?

• Presence of algae

• Absorption of sunlight

• Compression of snow over time

• Reflection of the sky

How far can icebergs travel from their origin?

• A few hundred miles

• Thousands of miles

• Up to the equator

• Only within polar regions

Which current traps most Antarctic icebergs?

• North Atlantic Drift

• Equatorial Current

• Circumpolar Current

• Gulf Stream

What type of marine life is commonly found around icebergs?

• Coral reefs

• Tropical fish

• Krill and jellyfish

• Sea turtles

What bird species nests on icebergs?

• Albatross

• Penguin

• Snow Petrel

• Seagull

What is the impact of iceberg melting on the surrounding ocean?

• Decreases ocean currents

• Creates a pool of fresh water

• Raises ocean temperature

• Increases ocean salinity
