As the amount of carbon dioxide in the atmosphere increases, what do many scientists predict will happen? a. trees will not have enough carbon dioxide for photosynthesis. b. more volcanoes will form mountains as the pacific plate moves due to plate tectonics. c. the earth will experience global warming due to the greenhouse effect. d. glaciers in greenland will react with the carbon dioxide to form new types of silica gel.

The right answer is C

The greenhouse effect is a natural phenomenon causing a rise in the temperature on the surface of our planet. Essential to our survival, this fragile balance is threatened. Human activities (like releasing an excessive amount of CO2) affect the chemical composition of the atmosphere and lead to the emergence of an additional greenhouse effect (because CO2 absorb more energy (heat) than the other oxygen), largely responsible for the current climate change.
