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.
Mono is âoneâ. which implies one sideband on each side of the carrier â¢ Frequency Modulation (FM) â One frequency (carrier) is speeding up and slowing down â FM is stereo.Spectrum Sidebands â¢ Amplitude Modulation (AM) â One frequency (carrier) is getting louder and softer at another frequency (modulating freq) â AM is mono.
