B. By trapping heat in the earth's atmosphere 全球变暖主要是由温室气体(如二氧化碳)在大气层中形成的“温室效应”导致的。这些气体能够吸收和辐射红外辐射,从而导致地球表面和下层大气的温度升高。因此,正确答案是 B. 通过在地球的大气层中捕获热量。 其他选项并非全球变暖发生的直接原因:森林砍伐会间接导致全球变...
Earth's sun does more than generate heat and light. The solar wind is a stream of electrically charged gas particles rushing out from the sun into space. The source is the sun's corona, an envelope of plasma so intensely hot that the sun's gravity can't
