Water
Weathering and erosion, along with thegravity-driven effect called mass wasting, are the fundamental processes by which rock is broken down and removed, collectively called denudation. The most important agent in both weathering and erosion is water, in both its liquid and solid states.
Answer:
Generally, a seismograph consists of a mass attached to a fixed base. During an earthquake, the base moves and the mass does not. The motion of the base with respect to the mass is commonly transformed into an electrical voltage. The electrical voltage is recorded on paper, magnetic tape, or another recording medium.
