Question

1. there is a direct correlation between the emissions of carbon dioxide into the atmosphere and the rise in the earths temperature. (true or false)

options: true, false

1. albedo is a term used to describe the fraction of the suns radiation that is reflected back into space by various surface of the earth. (true or false)

options: true, false

1. ice and snow have low albedo, while rocks and soil has high albedo since rocks and soil absorb more heat. (true or false)

options: true, false

Explanation:

Question 7

Carbon dioxide is a greenhouse gas. When its emissions increase, it traps more heat in the atmosphere, leading to a rise in Earth’s temperature. So there’s a direct correlation.

Albedo is defined as the fraction of solar radiation (sunlight) that is reflected by a surface (like Earth’s surfaces) back into space. So the statement matches the definition.

Ice and snow are highly reflective, so they have high albedo. Rocks and soil absorb more radiation (reflect less), so they have low albedo. The statement has them reversed, so it’s false.

Answer:

A. True
