The greenhouse effect is a dynamic process that affects Earth’s environment. It involves radiation, heat, and gases; it has both positive and negative results. Which of these is a positive result of Earth's greenhouse effect? A. It traps heat energy from the Sun, creating temperatures that sustain life on Earth.
B. It creates an increase in Earth’s temperature, melting ice at the poles and causing ocean levels to rise.
C. It removes volatile organic compounds from homes, decreasing the chances of respiratory problems.
D. It increases when gases are added to the atmosphere, which may cause climate to be warmer than it was 100 years ago.
