The axis of the earth is inclined to the plane of ecliptic at an angle of:

Correct option is D

The correct answer is (D)    ​66 1/2 degrees

Information booster:

The Earth has two main motions: rotation and revolution.

• Rotation is the spinning of the Earth on its axis.
• Revolution is the Earth's movement around the Sun in a fixed orbit.

The Earth’s axis, an imaginary line, is tilted at an angle of 66.5° relative to its orbital plane. This tilt, known as axial tilt, plays a crucial role in the changing seasons.

• A greater tilt leads to more extreme seasons: hotter summers and colder winters.
• A smaller tilt results in milder seasons: cooler summers and warmer winters.
• Cooler summers allow snow and ice to persist in high-latitude regions, which can eventually form large ice sheets.
• An increase in snow and ice causes more sunlight to reflect back into space, further cooling the Earth in a process called positive feedback.

These changes in tilt affect the Earth's climate, influencing long-term patterns such as ice ages and warmer interglacial periods.
