Understanding Winter Ecology and Adaptations

The video explores why Earth has seasons due to its tilt and orbit around the sun, leading to varying sunlight exposure. It explains snowflake formation, highlighting their unique structures and the conditions affecting them. The video also covers building a snowman, emphasizing balance and engineering principles. It discusses how animals adapt to winter with changes in fur and feathers, and offers tips on helping birds survive the cold by providing food and nesting materials.

What causes the Earth to have different seasons?

• The Earth's magnetic field

• The Earth's rotation speed

• The Earth's tilt and orbit around the sun

• The Earth's distance from the sun

Why do different parts of the world experience different seasons at the same time?

• Due to the Earth's magnetic field

• Because of the Earth's rotation

• Due to varying distances from the sun

• Because of the Earth's tilt and orbit

What is the basic structure of a snowflake?

• A six-sided crystal

• A ten-sided crystal

• A four-sided crystal

• An eight-sided crystal

What factors influence the shape of a snowflake?

• The altitude of the cloud

• The speed of the wind

• The time of day

• The temperature and water content in the cloud

What is the key to building a stable snowman?

• Using the same size snowballs

• Stacking the largest snowball at the top

• Stacking the largest snowball at the bottom

• Using only two snowballs

Why do Arctic animals change their coat color in winter?

• To signal other animals

• To scare off predators

• To blend in with the snow and stay warm

• To attract mates

How do Arctic foxes stay warm during winter?

• By building nests

• By migrating to warmer areas

• By growing a thicker, white fur coat

• By hibernating underground

What is one way people can help birds during winter?

• By providing them with blankets

• By offering them hot cocoa

• By putting out bird seed and water

• By building them small houses

Why is it beneficial to provide nesting materials for birds in winter?

• It makes them sing more

• It attracts more birds to the area

• It keeps them warm

• It helps them build nests for spring

What can you observe by watching birds during winter?

• Their nest-building activities

• Their migration patterns

• Their hibernation habits

• Their hunting techniques
