Why does Canada have distinct summer and winter seasons?

Canada experiences distinct summer and winter seasons primarily due to its geographical location and varying latitude. The country spans a vast area, resulting in significant differences in climate and temperature across regions. During summer, sunlight is more direct and days are longer, leading to warmer temperatures, while in winter, the tilt of the Earth's axis causes shorter days and colder temperatures. Additionally, factors such as ocean currents and topography influence local climate variations, further contributing to the seasonal differences.
