Continental drift theory
Answer (2)
Continental Drift Theory is the idea that Earth’s continents were once joined together in a single huge landmass called Pangaea, and over millions of years, they slowly moved to their current positions.This theory was first proposed by Alfred Wegener in 1912. He noticed that the coastlines of continents like South America and Africa seem to fit together like puzzle pieces. He also found that similar fossils, rocks, and mountain ranges exist on continents far apart today, suggesting they were once connected.This theory is important to learn becauseIt helps us understand Earth’s geological history.It explains why continents have similar plants, animals, and rock fossils formations even when they are far away.It laid the foundation for the Plate Tectonics Theory, which explains how continents keep moving today.
Answer:The Continental Drift Theory, proposed by Alfred Wegener in 1912, suggests that the continents on Earth have moved over time and were once joined together in a single supercontinent, known as Pangaea. The theory is supported by several lines of evidence, including:1. *Fit of the continents*: The continents fit together like a jigsaw puzzle.2. *Similar rock formations*: Similar rock formations and fossils are found on different continents.3. *Fossil evidence*: Fossils of the same age and species are found on different continents.4. *Coal deposits*: Coal deposits are found in regions that are now too cold to support plant life.The theory of continental drift laid the foundation for the development of plate tectonics, which explains the movement of the Earth's lithosphere.
