Revolution is the term used to describe the path (or orbit) of Earth through space. Earth's revolution around the sun is responsible for seasonal change and leap years. This path is shaped like an ellipse and has points when Earth is closer to the sun and farther from it.

**Revolution**

The correct answer is option 'B', Revolution.

**Explanation:**

The movement of the Earth around the Sun is called revolution. It is one of the two main motions of the Earth, the other being rotation. Revolution refers to the Earth's orbit around the Sun in a nearly circular path.

**Key Points:**

1. **Rotation:** Rotation refers to the Earth's movement on its axis. The Earth rotates from west to east, causing day and night. It takes approximately 24 hours for the Earth to complete one rotation. This rotation is responsible for the daily cycle of day and night.

2. **Revolution:** Revolution refers to the Earth's movement around the Sun. The Earth revolves around the Sun in an elliptical orbit. This revolution takes approximately 365.25 days to complete, resulting in one year. The elliptical shape of the Earth's orbit causes variations in the distance between the Earth and the Sun throughout the year, leading to the change in seasons.

3. **Solstice:** Solstice refers to the two points in the Earth's orbit where the Sun appears to reach its highest or lowest point in the sky at noon, resulting in the longest and shortest days of the year. There are two solstices in a year - the summer solstice and the winter solstice. The summer solstice occurs around June 21st in the Northern Hemisphere, marking the longest day of the year, while the winter solstice occurs around December 21st in the Northern Hemisphere, marking the shortest day of the year.

4. **Equinox:** Equinox refers to the point in the Earth's orbit where the Sun appears to be directly above the equator, resulting in equal day and night. There are two equinoxes in a year - the vernal (spring) equinox and the autumnal equinox. The vernal equinox occurs around March 21st in the Northern Hemisphere, marking the beginning of spring, while the autumnal equinox occurs around September 21st in the Northern Hemisphere, marking the beginning of autumn.

In conclusion, while rotation refers to the Earth's movement on its axis causing day and night, revolution refers to the Earth's movement around the Sun, resulting in one year and the change in seasons. Therefore, the correct term for the Earth's movement around the Sun is revolution.
