Antarctica

Today's goal: We will identify different parts of Antarctica and what we can learn from Antarctica.

What is today's goal?

• Analyze the geography of the Arctic
• Explore the wildlife of Antarctica
• Learn about the history of Antarctica
• Identify different parts of Antarctica and what we can learn from Antarctica.
• Discuss the climate of Antarctica

Which continent is Antarctica?

What are Antarctic ice shelves?

• Massive floating platforms of ice

• Solid icebergs floating in the ocean

• Large glaciers on land

• Frozen ocean water

How do Antarctic ice shelves form?

• By snow accumulating and compressing into ice

• By icebergs breaking off glaciers

• By ocean water freezing

• By glaciers melting into the sea

What role do Antarctic ice shelves play in the environment?

• They act as barriers, slowing the flow of ice into the sea

• They increase the flow of ice into the sea

• They have no significant role

• They cause glaciers to melt faster

Which factors influence the formation of ice shelves?

• Temperature, ocean currents, and seabed topography

• Wind speed, sunlight, and air pressure

• Animal activity, vegetation, and soil type

• Human activity, pollution, and deforestation

What effect do warmer temperatures have on ice shelves?

• They cause the ice to melt faster, affecting stability

• They make the ice thicker and more stable

• They have no effect on ice shelves

• They cause ice shelves to form more quickly

How do ocean currents affect ice shelves?

• By eroding the underside, thinning the ice shelf

• By making the ice shelf thicker

• By pushing the ice shelf further inland

• By having no effect on the ice shelf

What determines how far an ice shelf extends into the ocean?

• The shape and depth of the seabed

• The amount of sunlight

• The presence of marine life

• The air temperature

What is the primary focus of the research stations in Antarctica?

• Climate change, wildlife, and the unique environment

• Military activities and mineral mining

• Tourism and recreation

• Commercial fishing
