How are the words season.equinox and solstice related?

The terms "equinox" and "solstice" refer to key astronomical events that mark changes in the seasons. An equinox occurs when day and night are approximately equal in length, signaling the start of spring or autumn. In contrast, a solstice marks the points in the year when the Sun reaches its highest or lowest point in the sky at noon, indicating the beginning of summer or winter. Both events are crucial for understanding the Earth's tilt and orbit around the Sun, which directly influences seasonal changes.
