Why Polar Seasons Are Extreme

Question 1

Why do Arctic animals like polar bears have to travel farther to find food in the spring?

Accepted Answer

Because the Earth's tilt makes the North Pole face toward the Sun, causing sea ice to melt and open water, so polar bears must swim farther to reach ice where they can hunt seals.

Answer

Because the Earth's tilt makes the North Pole face away from the Sun, making it colder and causing sea ice to grow.

Answer

Because the Sun is farther away from Earth in spring, so there is less food for the animals.

Answer

Because strong winds push the animals toward the equator, away from their usual hunting spots.

Question 2

A scientist works at the South Pole. She finds that from early October until early March the Sun is visible the whole time, but from early March until early October the Sun never appears. Which statement correctly explains why this pattern happens?

Accepted Answer

Because the Earth’s axis stays tilted, the South Pole points toward the Sun for about half of the year (giving all‑day Sun) and points away for the other half (giving all‑day darkness).

Answer

Because the Earth spins more slowly at the poles, making the Sun rise for several months and then stay below the horizon for the rest of the year.

Answer

Because the South Pole always faces the same direction in space, so it only gets sunlight when the Sun moves close enough to that direction.

Answer

Because the Sun is farther away from the Earth during the months when it is not seen, its light is too weak to reach the pole.

Question 3

Lena sees the Sun moving in a circle and never setting at the North Pole in July, but in January the sky stays dark all day. Which explanation best describes why this happens?

Accepted Answer

Because Earth’s axis is tilted about 23.5°, the North Pole points toward the Sun in July (continuous daylight) and points away from the Sun in January (continuous darkness).

Answer

Because Earth is closer to the Sun in July, the Sun appears higher in the sky at the poles, and farther away in January so it disappears.

Answer

Because the North Pole has a special mirror that reflects sunlight during the summer months but turns off in winter.

Answer

Because the Sun moves faster across the sky in summer, so it never sets, and moves slower in winter, staying below the horizon.
