Practice Questions on Axial Tilt and Seasonal Changes

📚 Topic Summary

The Earth is tilted on its axis at approximately 23.5 degrees. This tilt is the primary reason we experience seasons. As the Earth orbits the Sun, different parts of the planet are tilted towards or away from the Sun, resulting in varying amounts of direct sunlight and thus, changes in temperature and weather patterns. The hemisphere tilted towards the sun experiences summer, while the hemisphere tilted away experiences winter.

🌡️ Part A: Vocabulary

Match the terms with their definitions:

1. Axial Tilt
2. Equinox
3. Solstice
4. Hemisphere
5. Orbit

Definitions:

1. One half of the Earth.
2. The path of an object around another object in space.
3. The inclination of the Earth's rotational axis in relation to its orbital plane.
4. When the sun reaches its highest or lowest point in the sky at noon, marked by the longest and shortest days.
5. When day and night are of equal length.

Match the number to the term. For example, if you think 'Axial Tilt' matches with definition '2', you would write '1-2'.

✏️ Part B: Fill in the Blanks

Complete the following paragraph using the words: Sun, Summer, Winter, 23.5, Equator.

The Earth's axis is tilted at ________ degrees. During ________, the hemisphere tilted towards the ________ experiences more direct sunlight. The ________ receives the most direct sunlight throughout the year. The opposite hemisphere experiences ________.

🤔 Part C: Critical Thinking

Explain how the seasons would be different if the Earth's axial tilt was 0 degrees.
