### Earth's Hydrothermal Vents and the Origin of Life
Two models describe the environment where life on Earth may have originated:
Model 1 (Hydrothermal Vent Model)
Life began near deep-sea hydrothermal vents. The hot, mineral-rich water emitted from these vents provided a continuous supply of chemical energy (such as hydrogen sulfide and methane) and metal catalysts necessary to synthesize the first organic molecules in the absence of sunlight.
Model 2 (Warm Little Pond Model)
Life began in shallow, terrestrial tidal pools. Wet-dry cycles driven by evaporation and rain concentrated organic compounds. Sunlight provided the energy source, and ultraviolet radiation catalyzed the chemical reactions needed to form complex polymers like RNA.
Match each of the environmental features or assumptions to the model classification that describes it.
- Deep-sea hydrothermal vents as the location of the origin of lifeA claim exclusive to Model 1
- Shallow, terrestrial tidal pools as the location of the origin of lifeA claim exclusive to Model 2
- An aqueous (water-based) environment is necessary for the formation of the first organic moleculesAn assumption shared by both Model 1 and Model 2
