Scientists currently monitor underground movements, such as earthquakes and nuclear tests, using seismometers – instruments that measure the motion of those events at the Earth's surface.
potential energy
you have potential energy when you're stopped. you have kinetic energy when you're moving. so as you're going down a hill, kinetic energy is increasing and potential energy is decreasing.
The polymerase chain reaction makes DNA fingerprinting more reliable because it allows scientists to quickly make many copies of DNA the answer is C
