A scientist observes that a region covered by permafrost a few years ago has now thawed. How could this trend be related to the use of fossil fuels?

Greenhouse gases trap more heat in Earth's atmosphere.

Particulate matter covers and warms the ground.

Soil thaws more easily as it becomes more acidic.

Factories using fossil fuels generate heat.

Respuesta :

Greenhouse gases trap more heat in Earth's atmosphere.

Greenhouse gases, such as CO₂, are released through the burning of fossil fuels to provide energy. They are called greenhouse gases because they produce a greenhouse effect in the atmosphere.

Explanation:

Greenhouses trap infrared radiation from the earth's surface that is supposed to escape to space. This results in global warming in the eath’s atmosphere.  

A general rise of temperature due to the greenhouse effect will cause permafrost to melt due to climate change. Structures initially built on the permafrost will begin to show cracks on the walls due to the buckling effect of the soil underneath as ice melts and drains from the soil.
