3. The Earth is currently tilted 23.5° from its axial plane and this axial tilt results in many remarkable effects, including the seasons around the planet. Elaborate (250 words)

Difficulty level: Easy

Reference: Down to Earth , Insights on India

Why the question:

As the Earth orbits the sun, it spins around an axis — picture a stick going through the Earth, from the North Pole to the South Pole. During the 24 hours that it takes for the Earth to rotate once around its axis, every point on its surface faces toward the Sun for part of the time and away from it for part of the time. This is what causes daily changes in sunlight and temperature.

Key Demand of the question:

To write about axial tilt of earth and its impact.

Directive word: 

Elaborate – Give a detailed account as to how and why it occurred, or what is the context. You must be defining key terms wherever appropriate and substantiate with relevant associated facts.

Structure of the answer:

Introduction: 

Define the concept of Earth’s axial tilt briefly.

Body:

First, write about the Earth’s axis of rotation is the line along which it spins around itself as it revolves around the Sun. The points on which the axis intersects the planet’s surface are the geographical north and south poles.

Next, mention the impact of axial tilt of earth – appropriate climate for Earth to support life, responsible for the formation of seasons, governs the warming strength of the sun’s energy etc.

Conclusion:

Conclude by summarising.
