The land area situated between the Cool Zone and the Warm Zone is termed the Transition Zone.

• A. Transition Zone
• B. Cool Zone
• C. Warm Zone
• D. Mid Zone

Answer: (A)

In turf climate terms, zones describe where different types of grasses perform best. The land area between the Cool Zone and the Warm Zone sits in a middle ground with hot summers and cool winters, so neither cool‑season nor warm‑season grasses are perfectly optimal there. That intermediate region is known as the Transition Zone, because it represents the shift from cool‑season conditions to warm‑season conditions over the year. So the Transition Zone is the correct term for the land area between Cool Zone and Warm Zone. The Cool Zone name would imply conditions favoring cool‑season grasses, not the in-between area, and the Warm Zone name implies conditions favoring warm‑season grasses. Mid Zone isn’t the standard term used to describe turf climate zones.
