Question

Quizplus · Accepted Answer

A decreasing albedo means that more solar radiation is being absorbed, rather than reflected, which leads to a warming trend in the planet's climate.

Answer: B 
 An increase in greenhouse gases traps more heat in the planet's atmosphere, leading to a gradual warming trend in the climate.

Answer: C 
 A decrease in the brightness of the Sun would result in less solar radiation reaching the planet, which would cause a cooling trend rather than a warming trend.

Answer: D 
 A major volcanic eruption that increases the albedo of the planet by making clouds would actually lead to a cooling trend in the climate.

Therefore, the best choices that could explain a gradual warming trend in a planet's climate are A and B.
