The Earth’s Crust Doesn’t Stop – Scientists Discover Old and New Continents
Scientists have discovered an unexpected new continent hiding beneath Greenland. Zealandia, thought to be a candidate for Earth’s eighth continent, has been almost completely submerged by the sea. The new ocean could split Africa into two continents. Doggerland: Before it was inundated by a tsunami 8,000 years ago, this landmass connected Britain and continental Europe. Archaeologists and citizen scientists have discovered a number of artifacts from Doggerland over the years, including a deer bone with an arrowhead and a fragment of a human skull.
Earth’s plate tectonics began earlier than 4 billion years ago
New research suggests that plate tectonics began earlier than 4 billion years ago — shortly after Earth formed. New research suggests that plate tectonics, which causes earthquakes, mountain formation and the separation of continents, may have begun when Earth was just forming — much earlier than many scientists thought.
The earth’s crust is unstable
The Earth is starting to shake because of global warming. Tectonic plates are moving apart regardless of warming: the giant tectonic plate under the Indian Ocean is splitting apart, the Dead Sea Fault in the Middle East is moving about twice as fast, or 0.2 inches (0.4 cm) per year, while the San Andreas Fault in California is moving about 10 times faster, about 0.7 inches (1.8 cm) per year.
Earthquakes continue to rage along the Pacific coast
A strong earthquake occurred off the coast of Sakhalin on August 10, a powerful earthquake occurred off the coast of Japan on August 8, and an earthquake occurred off the coast of the Southern Kuril Islands on July 30. A strong earthquake occurred in Taiwan on April 3, which was the most powerful on the island in the last 25 years.
