Biomes. World Biome Information. World Climates. Some facts about climate The sun's rays hit the equator at a direct angle between 23 ° N and 23 ° S latitude.
Radiation that reaches the atmosphere here is at its most intense. In all other cases, the rays arrive at an angle to the surface and are less intense. The closer a place is to the poles, the smaller the angle and therefore the less intense the radiation. Earth Floor: Biomes.
