Question

(Earth-Space)

Which statement describes a potential cause-and-effect relationship for Earth's climate?
A. The continents cluster together, causing the climate to become warmer.
B. Erupting volcanoes emit carbon dioxide, causing the climate to become cooler.
C. The Sun becomes less bright over time, causing the climate to become cooler.
D. Meteors that impact Earth throw dust into the atmosphere, causing the climate to become warmer.

Answer 1

The answer is D the impact of a meteor hitting the ground would cause dust to go flying and hence forth would block sunlight meaning the Earth would cool till the dust clears Or the answer is A DONT CHOOSE B Or C the sun is not dimming anytime soon

Answer 2

The answer is B. Erupting volcanoes emit carbon dioxide, causing the climate to become cooler.
When volcanoes erupt, they emit a mixture of gases and particles into the air. Some of them, such as ash and sulfur dioxide, have a cooling effect, because they (or the substances they cause) reflect sunlight away from the earth. Others, such as CO2, may cause warming by adding to the greenhouse effect.
