Volcanoes, hot springs, and geysers: caused by heat from the decay of radioactive isotopes i(cid:374) ea(cid:396)th"s (cid:272)(cid:396)ust. Another consequence of radiation is volcanoes, hot springs, and geysers. A hot spring is a warm pool of water.

In both cases, what happens is that heat from melted underground rock called magma, heats up the water above it, by conduction. Volcanoes are found all over the world, but we find about 75% of them concentrated within a region of earth called the ring of fire. This refers to a ring of coastline around the pacific ocean, both on the west side of the coastal americas and the east coast of. Asia and the many islands in the south pacific.
