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.
A voltage buffer amplifier is used to transfer a voltage from a first circuit, having a high output impedance level, to a second circuit with a low input impedance level. The interposed buffer amplifier prevents the second circuit from loading the first circuit unacceptably and interfering with its desired operation.
