Answer:
Changes in solar energy
Explanation:
When released into the atmosphere, certain gases act like a blanket, preventing heat from escaping. One of the most important heat-trapping gases is carbon dioxide (CO2), which is released when we burn fossil fuels like oil, coal, and natural gas.
Once released, carbon dioxide stays in the atmosphere for roughly 40 years, though its effects stay much longer; other gases, like methane, are even longer-lived. The cumulative effect is to raise the planet’s temperature.
<u>Answer</u>:
This is due to the unequal resource distribution across the land and the distribution of resources depends upon the physical factors like the land and the climatic conditions. Some places are filled with more resources while some are filled with scare resources. The countries which have more resources are wealthy while the countries which do not have that much resources are not wealthy. The metals are also unevenly distributed on the earth’s crust and the most abundant metal is aluminum and silicon. Some of the distracted metals which are found deep in the earth’s crust and then extracted in the ore form from the mines. The most important reason for the uneven distribution of metals in Earth's crust are their physical factors like the climate, land and their topography.
71% of the Earth is covered in water.
