Concept:The Earth's temperature distribution is influenced by latitude, altitude, and seasonal changes, but equatorial regions experience minimal temperature variation between January and July.
Explanation:Step 1: Due to the Earth's curvature, solar radiation intensity decreases from the equator toward the poles. Hence, temperature generally decreases from the equator to the poles – Statement A is correct.
Step 2: Equatorial regions receive near-vertical sunlight year-round, so their temperature changes very little between January and July. Statement B claims substantial change — this is false.
Step 3: Large landmasses in subarctic and arctic zones lose heat rapidly in winter, leading to extremely low temperatures at their centers. Statement C is correct.
Step 4: As altitude increases, the atmosphere becomes less dense and temperature decreases. Thus, highlands are always colder than surrounding lowlands – Statement D is correct.
Answer:Option B – "Temperatures in equatorial regions change substantially from January to July" is the incorrect statement.
