Question

2 scientists have proposed that at one time in earths history there was a supercontinent called pangaea, as shown in the diagram.pangaeanorth americaeurasiaafricasouth americaindiaaustraliaantarcticawhich statement describes the causes that most likely led to the breaking apart of pangaea?a solar radiation from the sun along with meteor impacts caused cracks to form in pangaea.b convection in earths interior caused pangaea to separate into several different landmasses.c weathering and erosion caused earthquakes that resulted in breaks in the continental crust.d forces from within earth resulted in some areas sinking below sea level and others rising upward.

Explanation:

The breakup of Pangaea is explained by plate tectonics, driven by convection currents in Earth's mantle (interior). These currents move the tectonic plates that carry continental crust, pulling Pangaea apart over time. Option A is incorrect because solar radiation and meteor impacts are not the main cause. Option C is wrong as weathering/erosion do not cause crust-breaking earthquakes for continental drift. Option D describes vertical crust movement, not the horizontal separation of continents.

Answer:

B. Convection in Earth's interior caused Pangaea to separate into several different landmasses.
