Magma can partially crystallize at depth and then rise to shallow depths where the remaining magma solidifies. the early-formed crystals are phenocrysts and the texture is porphyritic. in Lava or near the earth surface,very large crystals can grow, forming intrusive rocks or volcanic rocks . magma that cools in <span>shallow magma chambers </span> has a relatively short time to cool and so forms <span>fine grained rocks </span>, but not volcanic glass. in deep magma chamber, magma cools at a slow rate, allowing the formation of extrusive or plutonic rock .

Which is correct about an ammeter?
s344n2d4d5 [400]

Answer:

b. The internal resistance must be much smaller than the other resistances in the circuit.

Explanation:

Ammeter is used to measure the current flowing through a circuit. It is connected in series configuration with the load. In such a scenario the resistance of the ammeter should be negligible so as to make sure that the voltage drop across the resistance of ammeter is zero and it shows the correct reading of the current in the circuit.
