Final answer:
Tropical climates receive more rainfall compared to Moist Continental Mid-Latitudes. Moist Continental Mid-Latitudes experience more extreme temperature variations.
Step-by-step explanation:
The main difference between tropical (A) climates and Moist Continental Mid-Latitudes (D) is that tropical climates receive more rainfall than Moist Continental Mid-Latitudes. Tropical climates, characterized by warm temperatures year-round, experience high levels of precipitation, typically in the form of rain. On the other hand, Moist Continental Mid-Latitudes have more extreme temperature variations, with cool to hot summers and cold winters. These regions are often located in the interiors of continents, away from large bodies of water.
