TECTONICS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The evidence supporting continental drift supports plate tectonics, because plate tectonics is a modified, expanded version of continental drift hypothesis. In the mid 1900s, additional evidence was found that led to the development of the theory of plate tectonics. Which is an example of this additional evidence?
A
coal deposits in areas that are not tropical
B
sea-floor processes
C
matching animal fossils found on different continents
D
plant fossils found on different continents
Explanation: 

Detailed explanation-1: -Fossil Evidence One type of evidence that strongly supported the Theory of Continental Drift is the fossil record. Scientists have found fossils of similar types of plants and animals in rocks of similar age. These rocks were on the shores of different continents.

Detailed explanation-2: -The matching of continents, rocks of the same age across oceans, tillite, placer deposits, and fossil distribution are all Evidence of Continental Drift Theory.

Detailed explanation-3: -Alfred Wegener in Greenland. Plate tectonics is the theory that Earth’s land masses are in constant motion. The realization that Earth’s land masses move was first proposed by Alfred Wegener, which he called continental drift.

Detailed explanation-4: -Plate tectonics is considered a “unifying theory” in the field of geology because it synthesizes the work and theories of most other areas of geology (Oreskes and LeGrand 2003). The generation of mountains, deep-sea trenches, volcanic chains, island arcs, and rift valleys can be explained by plate motions.
