Continent drifts
Explanation:
The use of fossil evidences to support the correlation of land masses that are presently not together can suggests that continents do move and land masses can change position.
This was one of the earliest prove suggest by Alfred Wegener to back up his theory of continental drift.
- Since fossils are evidence of prehisotric life, a place originally together should have the same fossil contents.
- When they become separated, the fossil contents in their lithology should match.

Answer:
Explanation:
Hello,
In this case, it is firstly necessary to compute the dissolved moles of hydrogen chloride into the water as shown below:
Thus, the molarity is computed as shown below:
Wherein no change in volume is considered, therefore the volume of the solution was the same volume of water.
Best regards.
