What characteristic is true about the Humid Continental climate?

The Humid Continental climate is characterized by having four distinct seasons—winter, spring, summer, and fall. This climate type experiences significant variations in temperature and precipitation throughout the year, which is a defining feature of the seasons.

During winter, temperatures can drop substantially, and snowfall can occur, while summers can be warm to hot, depending on the specific geographical location. The presence of these marked seasonal changes and the differences in temperature and precipitation patterns are critical to recognizing this climate.

The other options do not accurately represent the Humid Continental climate. The climate does not have extremely mild winters, nor does it support a single climate season or maintain consistent high temperatures year-round. Instead, the combination of temperature fluctuations and diverse seasonal attributes is what distinguishes the Humid Continental climate.
