longer days

1. choose the correct answer.

why might carbon dioxide cause the atmosphere to get warmer?

carbon dioxide is a hotter molecule than oxygen.
carbon dioxide makes the suns energy stronger as it passes through it.
carbon dioxide traps heat.

Explanation:

Question 11

Global warming refers to the long - term increase in Earth's average surface temperature. Climate change encompasses long - term changes in temperature, precipitation, and other aspects of the climate system, and global warming is a major part of climate change. Radioactive decay is related to the breakdown of atomic nuclei, ozone depletion is about the reduction of the ozone layer, and longer days are related to the Earth's rotation and orbit in a different context, not to global warming.

Carbon dioxide is a greenhouse gas. Greenhouse gases in the atmosphere, like carbon dioxide, have the ability to trap heat (infrared radiation) that is emitted from the Earth's surface. Carbon dioxide does not get warm fast in a way that causes atmospheric warming, it is not a hotter molecule than oxygen in a sense that causes warming, and it does not make the sun's energy stronger.

Answer:

C. climate change
