Final answer:
The greenhouse effect directly contributes to global warming by trapping heat in Earth's atmosphere.
Step-by-step explanation:
The "greenhouse effect" contributes directly to global warming. The greenhouse effect is a natural process that occurs when certain gases in Earth's atmosphere trap heat from the sun and prevent it from escaping back into space, thus warming the planet. The primary greenhouse gases responsible for this effect are carbon dioxide, methane, and water vapor. These gases are released into the atmosphere through various human activities, such as burning fossil fuels and deforestation, which have led to an increase in their concentrations and subsequent global warming.
