Continental roots stress Earth's surface. FULL STORY. The Earth's rigid lithosphere varies laterally in thickness and strength. Areas of thicker, older lithosphere known as continental roots penetrate deeper into the mantle in some places under continents.
A monoblock is a type of amplifier used in car audio systems. What  the monoblock type of amplifier does is to split the two channels  of audio into two separate mono systemâ¦s, giving a little more kick  to the bass coming out of subwoofers.
Monopole antennas consist of a single radiating element such as a metal rod, often mounted over a conducting surface, a ground plane. One side of the feedline from the receiver or transmitter is connected to the rod, and the other side to the ground plane, which may be the Earth.
