When people speak about convection, they are usually referring to the uneven heating that occurs on the surface of the earth.
Consequences of an inconsistent heating system:
Because of the disparity in temperature distribution, certain areas of the environment are hotter than others, and there are also shifts in volume and tension as a result.
It generates updrafts, which in turn may lead to thunderstorms and other types of severe weather.
The Earth has moved slightly on its axis.
Because the sun's rays are directed directly at the equator, the temperature there is higher than in other parts of the planet.
As you approach farther north or further south of the equator, they drop down in an incline or at an angle.
Because of this, the temperature of the earth is uneven, which in turn shapes the wind and the flow of the sea and makes it possible for life to exist.

Answer:
Some islands have older islands at one end of the chain and younger islands at the other end. Example is the Hawaiian Islands.
Explanation:
Volcanic mountains or islands are formed when the tectonic plates in the earth’s crust converges. The string of Hawaiian volcanic islands were formed as a result of the movement of the Pacific plate over a fixed hotspot, where the magma rises upward and erupts on the seafloor. The northwestern islands are older than the islands to the southeast side of the Hawaiian islands.
The age of a volcanic rock is calculated by measuring the amount of argon and the amount of radioactive potassium present in the rock. These measurements are the supporting evidence which showed that the southeastern end of the chain is younger than the northwestern part of the chain. The volcanic islands gradually subside and erode as they age, so the older islands have much lower elevations than the newer islands. This is another evidence which supports the conclusion.
