Fault correct answers A plane in rock along which movement occurs Liquefaction correct answers - A process by which water-saturated sediment temporarily loses strength and acts as a fluid - When the ground is a poorly consolidated sediment or sedimentary rock with water in the pore spaces, shaking can cause the sediment to become like quicksand. - Dry/wet sand analogy Fractional Melting correct answers A mixture of molten and solid rock when the entire rock does not have the same melt...

Amphoteric correct answers a substance that can act as both an acid and a base Cohesion correct answers water sticks to itself. gives water surface tension and it has the highest cohesion of all nonmetallic liquids. Adhesion correct answers water sticks to other things. specific heat correct answers the heat required to raise the temperature of the unit mass of a given substance by a given amount (usually one degree). At what temperature is water most dense? correct answers 4 deg...
