What might cause the average temperature of earth to increase?

plato users: increased levels of carbon dioxide from burning fossil fuels

Explanation:

increased levels of carbon dioxide from burning fossil fuels

Fossil fuels release carbon dioxide into the atmosphere. The burning of fossils shoots up carbon emission and leads to gloabl warming.

Carbondioxide is one of the greenhouse gases. Others are methane, water vapour.

Incoming radiation that reaches the surface can either be reflected or be absorbed on the earth surface. The part that is absorbed helps keep surface temperature in check. The reflected component of the radiation can get trapped when they come in contact with greenhouse gases like carbondioxie. The gas prevents the radiation from escaping the earth.

As the radiation lingers, it shoots up the earth temperature significantly.

The more the gases in the atmosphere the more the temperature rises.

Carbondioxide emission from various sources, chief of which is through burning of fossil fuels in industrial processes and automobiles have become a global problem.

When the earth warms, polar ice would recede and add more water to hydrosphere. This has been one of the leading cause of the increasing level of inundation the earth has been plagued with over the years.

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
