WebThe greenhouse effect causes some of this energy to be waylaid in the atmosphere, absorbed and released by greenhouse gases. Without the greenhouse effect, Earth’s temperature would be below freezing. It is, in part, a natural process. However, Earth’s greenhouse effect is getting stronger as we add greenhouse gases to the atmosphere. WebThe liquid must first be cooled to its freezing point (the same temperature as its melting point). Continuing to cool the liquid decreases the energy of the particles and they return …
