Answer:
<u>Fossil fuel- </u>The sources of fossil fuels are directly from the plants and animals, that are buried millions of years back and are converted into fossil now.
The consumption of fossil fuel leads to the emission of carbon into the atmosphere that is responsible for the increasing global temperature. This is one of the major problem of fossil fuel use.
<u>Nuclear fuel-</u> Nuclear fuels are derived from the radioactive elements such as uranium, strontium and potassium.
One of the major problem of using nuclear fuel is that it releases radioactive waste, that are harmful for various life forms.
<u>Renewable fuels-</u> This are renewable energy that can be generated again and again and are directly derived from the wind, water and the sun. For example, wind mill, solar panels and dams.
One problem of renewable fuels is that it has a lower production of energy such as electricity in comparison to the fossil fuels.
In the age of exploration.... Prince Henry showed the Portuguese how to navigate by studying the sun and stars until later on, he showed them the compass navigation as the only technology advance which made possible for them.
It is clear that from 2006 to 2012, the average insolation reflected by the Greenland ice sheets is decreasing. This indicates that each year, the amount of solar radiation that the ice sheets are able to reflect is decreasing. The level of insolation reflected is dependent on the area of ice sheets capable of reflecting the solar energy. Since the insolation reflected has decreased, this may mean that the area of the ice sheets has decreased as well.
