Question

Present three pieces of evidence supporting the theory that plates were once part of a super-continent.

a) Glacial evidence, paleontological similarities, magnetic reversals
b) Continental drift, volcanic activity, seismic waves
c) Tectonic plates, fossil records, earthquake patterns
d) Mountain formations, seismicity, mantle convection

Answer 1

Glacial evidence, paleontological similarities, and magnetic reversals support the theory of plate tectonics and the existence of a super-continent.

Step-by-step explanation:

The three pieces of evidence supporting the theory that plates were once part of a super-continent are:

1. Glacial evidence: Glacial striations and till, which are found across multiple continents, suggest that these land masses were once connected and covered by a single ice sheet.
2. Paleontological similarities: Matching fossils and similar species found on different continents provide evidence that these land masses were once joined.
3. Magnetic reversals: The pattern of magnetic reversals recorded in rocks on either side of mid-oceanic ridges supports the idea that these ridges were once part of a single land mass.
