Cromwell Current and Penguin Habitats

Emily from Minotaur explains how penguins, typically found in cold climates, also inhabit the Galapagos Islands due to the Cromwell Current. This current brings cold, nutrient-rich water to the surface, supporting algae growth and the penguins' food chain. The video also discusses ocean mixing, comparing it to salad dressing, and explains why penguins are absent from northern oceans despite climate changes.

Where do most penguins typically live?

• In tropical regions

• In cold waters near Antarctica

• In deserts

• In the Arctic

What is the Cromwell Current known for?

• Increasing ocean salinity

• Bringing cold water to the Galapagos Islands

• Creating large waves

• Warming the ocean surface

Why is the Cromwell Current important for penguins?

• It provides them with shelter

• It helps them migrate

• It brings nutrients and sunlight together

• It increases water temperature

What analogy is used to describe the ocean's nutrient and sunlight separation?

• A layered rock

• A mixed drink

• A salad dressing

• A layered cake

Why do cold surface waters mix more readily with nutrient-rich waters below?

• Because of ocean currents

• Due to the presence of fish

• Because of the sun's heat

• Due to the density of cold water

Why are there no penguins in the northern oceans?

• They evolved in the southern hemisphere

• They are hunted in the north

• They cannot survive in cold climates

• They prefer tropical waters

What prevents penguins from migrating to the Arctic?

• Too much warm, nutrient-poor water

• Lack of food

• Strong ocean currents

• Predators

Where are the world's only northern penguins found?

• In the Sahara Desert

• On the Galapagos Islands

• In the Amazon Rainforest

• In the Arctic

What is unique about the Galapagos penguins' location?

• They are found in freshwater lakes

• They live just above the equator

• They are found in deserts

• They live in the Arctic
