The Sun warms equatorial regions of Earth Low than the poles. This causes an area of toward pressure to develop near the equator. As a result, the northeast and southeast trade winds are created as air at the surface then flows less the equator.
<h3>Why does
air tend to rise in equatorial regions?</h3>
The reason of the air tends to rise in equatorial regions because in the equatorial regions there is more sunlight as compared to other areas. There is difference in the heat in different areas due to that warmer air rises.
Thus, option B is correct.

Answer:
Weather patterns don’t tend to change with altitude
Explanation:
More than 75 percent
Explanation:
Let us carefully analyze this problem:
The half life of the rubidium isotope = 50 billion years
The half-life of a radioactive isotope is the time it takes for it to decay to half of its original amount.
Every 50years, we know that a rubidium isotope would split into half.
Initially when the isotope was formed, we would only have the parent atoms there. There wont be any daughter;
ratio of parent to daughter = 100 : 0
When the isotope decays to half; we would have equal number of parent and daughter:
ratio of parent to daughter at half life = 50 : 50
The age of the earth is about 4.6billion years;
this is;
x 100 = 9.2% of the half-life of the rubidium isotope.
At this time, we should know that only 9.2 percent of the daughter would have been formed.
The remaining parent would be 100 - 9.2 = 90.8% would still be left undecayed.
The ratio of parent to daughter = 90.8 : 9.2
This is more than 75% of the parent
