Question

1. sep communicate information describe the hypothesis of continental drift.

Explanation:

The continental drift hypothesis, proposed by Alfred Wegener, states that the Earth's continents were once joined together in a single supercontinent called Pangaea and have since moved apart over geological time. Evidence for this includes the matching shapes of continental coastlines (like South America and Africa), similar rock formations and fossils across different continents, and paleoclimatic indicators (e.g., glacial deposits in areas that are now tropical). The continents are thought to have "drifted" across the ocean floor, though the mechanism for this movement (later explained by plate tectonics involving tectonic plate movement due to mantle convection) was not fully understood by Wegener initially.

Answer:

The continental drift hypothesis (proposed by Alfred Wegener) posits that Earth’s continents were once part of a single supercontinent (Pangaea) and have slowly moved apart over millions of years. Evidence includes matching continental coastlines, similar rock/fossil records across continents, and paleoclimatic clues. Wegener suggested continents “drifted” across the ocean floor, with plate tectonics (later developed) explaining the mechanism (mantle convection driving tectonic plate movement).
