question 3 (5 points)
what is causing an increase in the earths atmospheric temperature?
a) the position of the sun
b) use of alternative fuels
c) greenhouse gases
d) thickening of the ozone layer

Explanation:

🆕 New Concept Discovered: Greenhouse Effect
How trapped heat warms the planet

Step 1: Understand the greenhouse effect

The greenhouse effect is a natural process where certain gases in Earth's atmosphere trap heat from the Sun, preventing it from escaping back into space. This process keeps our planet warm enough to sustain life.

Step 2: Identify the cause of rising temperatures

When human activities release excess amounts of these heat-trapping gases—such as carbon dioxide (\(\text{CO}_2\)) and methane (\(\text{CH}_4\))—into the atmosphere, they trap more heat than normal. This enhanced greenhouse effect leads to a steady increase in the Earth's average atmospheric temperature, commonly known as global warming.

Step 3: Evaluate the given options

• a) the position of the sun: While solar cycles affect climate over long periods, the current rapid increase in temperature is not caused by changes in the sun's position.
• b) use of alternative fuels: Alternative fuels (like solar or wind energy) reduce emissions and help slow down temperature increases, rather than causing them.
• c) greenhouse gases: These gases directly trap infrared radiation (heat) in the atmosphere, causing temperatures to rise.
• d) thickening of the ozone layer: The ozone layer protects Earth from harmful ultraviolet (UV) radiation, but its thickness is not the primary driver of global atmospheric warming.

Answer:

c) greenhouse gases
