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.
