Tectonic plates are the surface of each and every thing on earth. all land forms rest upon them. When the plates shift, so does everything above it. But one thing is that you can barely notice it, approx. 1 inch year
Explanation:
<u>Hydrogen is used as fuel in automotives . It yields very high energy on combustion. It has great energy density by weight but poor energy density by volume. This is because Hydrogen is a very light gas, approx. 11 times lighter than normal air.</u> Hence it would require large volume of container to store it at normal atmospheric pressure conditions. That is why it is compressed using external energy to increase its density and decrease the volume needed for storage . So it becomes portable.
Only problem in this approach is that it utilities about 20% energy of the Hydrogen's energy potential to compress it . But this method proves cost effective as it reduces the overall weight of the container and also gives space to vehicles .
The answer is 3. because the sun's rays fall most directly on the equator, not on the poles. Hope this help :)
It would be to describe Earth.
Geo- means of or relating to the earth.
-graphy means a descriptive science.
So in a literal sense, it would be to describe earth. :)
