How many seasons are there in a year?

A year is divided into four distinct seasons: spring, summer, autumn (or fall), and winter. This division is based on the Earth's tilt in relation to its orbit around the sun, which leads to varying climatic conditions and patterns throughout the year. Each season typically has defining characteristics such as temperature ranges and daylight hours that vary significantly from one to another.

This concept of four seasons is widely recognized in many parts of the world and is an important part of agricultural practices, cultural events, and social activities. While some regions may experience a different number of seasons or have titles for additional transitional periods, the standard accepted number of seasons within a year is generally four, making this choice the correct answer.
