Can be found in- igneous rocks
Uranium is extremely hot
Extreme radiation its got
Causes death by the pounds
Its found in a lot of rock mounds
Its used for nuclear fuels
But its temperature doesn’t get cool
In 1789 I was discovered by Martin Klaproth
He of course found it in an igneous rock
Its used for inertial guidance devices
Its radiation is going to cause a crisis
Its classification is rare earth
The beginning of time is the time of its birth
