Answer:
c. are renewable
Explanation:
There are many energy sources that the humans have learned to use and exploit. Some resources are non-renewable, while some a re renewable. The non-renewable tend to be cheaper for the time being, and they also tend to produce more energy, but the problem is that the reserves will eventually run out. On the other side, the renewable resources are constantly out there, and they can not be spent, which gives them the advantage on the long run.
The alternative energy sources have been more and more in the focus, especially when it comes to the more developed nations. The main reasons for this are that the fossil fuels will eventually run out, and that they are more environment friendly. This has led to development of technology that is able to harvest energy from the sun, water, and wind, all which are natural resources that are constantly present and can not be spent. Some nations have invested so much in these resources that they have gradually started to replace the fossil fuels, with the end goal being stopping the usage of the fossil fuels totally.
Answer:The phase of moon when between new moon and half moon is crescent and more than half and less than full is gibbous. Thus, during waxing gibbous and waning gibbous, the phase of the moon would be more than half of moon's surface.
Explanation:Waxing gibbous
overinflated tires are more prone to blowout
Answer:
They receive less radiation from the sun, due to their orientation relative to incoming sunlight.
Explanation:
Earth has multiple different climate zones, roughly arranged by latitude. The difference in climates comes because of multiple factors, but the most important one is the Sun and the sunlight of it. Because Earth has a rounded shape, different parts of it receive different amounts of sunlight.
If we compare the tropical and polar regions as two contrasting regions, we can see huge differences. The tropical regions are warm or hot all year round, while the polar regions are very cold throughout all of the year. The tropical regions though receive sunlight at a much more direct angle, thus the sunlight is much more concentrated and heats up the region. The polar regions receive sunlight at a very low angle, so they are dispersing over a very wide area so they can not warm up the region.
