14.How can be determined the past positions of the continents?​

The past positions of the continents can be determined by using six major lines of evidence: paleomagnetism, linear magnetic anomalies, hot-spot tracks, paleobiogeography, paleoclimatology, and geologic and tectonic history.

Explanation:

the answer would be 3

answer: zinc is the substance which has a volume of 1.38 .

density is defined as the mass of an object per unit volume.

it can be calculated by dividing mass of a substance by its volume i.e.

si unit of density is kg per cubic meter and cgs unit of the same is gram per cubic centimeter.

now from the given data volume can be calculated by the formula .

hence, the volume of aluminium will be = which comes out to be 1.703 .

similarly, volume of zinc, chromium, and nickel will be 1.378 , 0.869 , and 0.356 respectively.
