What is the tilt of the Earth during the spring and fall equinoxes?

Back

The Earth is tilted neither toward nor away from the sun (tilt is side to side).

Front

What are the primary reasons for the seasons on Earth?

Back

Earth's tilt and revolution around the sun.

Front

During which equinoxes do you experience similar amounts of daylight?

Back

Spring and fall equinoxes.

Front

Why do we experience less sunlight in winter compared to summer?

Back

The Earth is tilted away from the Sun, resulting in shorter daylight hours.

Front

Explain the concept of Earth's axial tilt.

Back

Earth's axial tilt is the angle between Earth's rotational axis and its orbital axis, approximately 23.5 degrees, affecting seasonal changes.

Front

What is the significance of the Earth's revolution around the sun?

Back

The Earth's revolution around the sun, taking about 365.25 days, is responsible for the changing seasons.

Front

How does the Earth's rotation affect day and night?

Back

The Earth's rotation on its axis causes different parts of the planet to face the sun or be in shadow, creating day and night.
