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.

Answer:
The Spratly Islands are geopolitically significant because of the oil and natural gas deposits found in the bed of its territorial waters.
Explanation:
The Spratly Islands are an archipelago in the southwestern part of the South China Sea. The islands do not have a resident population, ports or harbors, but there are four airports. Currently, the archipelago is used as a fishing area.
The territory of the islands is disputed by six states: Vietnam, China, Taiwan, Malaysia, the Philippines and Brunei. Despite their tiny size, the islands of the archipelago are important in terms of presence in the region. In addition, studies indicate the presence of a significant amount of oil and gas. According to the US Department of Energy, up to 5.4 billion barrels of oil and up to 55.1 trillion cubic meters of natural gas are concentrated in the Reed Bank area of the archipelago.
About 45 islands are occupied by relatively small military contingents from Vietnam, China, Malaysia, the Philippines and Taiwan. The Brunei fishery area includes the southern reef, but Brunei has not made any official territorial claims.

This can be problematic for future generations because the newer generations are the ones to support the retiring generations. Labor forces will shrink and this will then hurt the economy.
