GEOLOGY

Detailed explanation-1: -C. The continents used to be all connected in one continent. Explanation: The break up of Pangea began between 240 & 200 million years ago as a result of the movement of the Earth’s tectonic plates and mantle convection.

Detailed explanation-2: -Pangaea existed about 240 million years ago. By about 200 million years ago, this supercontinent began breaking up. Over millions of years, Pangaea separated into pieces that moved away from one another. These pieces slowly assumed their positions as the continent we recognize today.

Detailed explanation-3: -Which statement is TRUE according to plate tectonic theory? Plates of rigid lithosphere lie on top of the weak asthenosphere. Seafloor spreading occurs at this type of plate boundary. According to plate tectonic theory, convergence between two plates of ocean lithosphere created these volcanoes.

Detailed explanation-4: -Use fossil and rock evidence to reconstruct how the Earth may have looked approximately 290 million years ago when the continents were connected to form a supercontinent called Pangea.

Detailed explanation-5: -He hypothesized that all of the modern-day continents had previously been clumped together in a supercontinent he called Pangaea (from ancient Greek, meaning “all lands” or “all the Earth”). Over millions of years, Wegener suggested, the continents had drifted apart. He did not know what drove this movement, however.
