Based on the knowledge about radioactive elements, the decay of radioactive elements such as uranium creates heat especially in Earth's crust, where these elements are abundant.
<h3>What are radioactive elements?</h3>
Radioactive elements are elements which undergo spontaneous decay of their nucleus and in the process produce elements with smaller atomic masses with the release of radiation and heat.
Examples of radioactive elements include uranium and radium.
Therefore, the decay of radioactive elements such as uranium creates heat especially in Earth's crust, where these elements are abundant.

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.
