Which zone near the equator is hot and humid year-round with dense vegetation?

• A. The Tropical Zone
• B. The Polar Zone
• C. The Temperature Zone
• D. The Alpine Zone

Answer: (A)

Near the equator, sunlight hits the surface more directly all year, so temperatures stay very high. That warmth rises into the atmosphere and, with the abundant heat and moisture, drives frequent rainfall. The combination of constant warmth and heavy rainfall creates lush, dense vegetation, like rainforests. This pattern defines the tropical zone, which lies around the equator between about 23.5° North and 23.5° South. In contrast, the Polar Zone is cold year-round with little plant life, the Temperature Zone experiences distinct seasons, and the Alpine Zone is found at high elevations with cold, sparse vegetation. So the zone near the equator that is hot and humid year-round with dense vegetation is the Tropical Zone.
