Exploring Earth's Geological Past
Plate Tectonics and Continental Drift
Plate tectonics is the theory that explains how the Earth's surface is divided into large plates that move. This movement causes continents to drift apart or come together. Here are some key points about plate tectonics:
Continental Drift: Continents were once joined together in a supercontinent called Pangaea.
Plate Boundaries: There are three types of plate boundaries: convergent, divergent, and transform.
Earthquakes and Volcanoes: Most earthquakes and volcanoes occur along these plate boundaries.
Mass Extinctions and Biodiversity
Throughout Earth's history, there have been several mass extinctions that drastically changed life on the planet. Here are some notable events:
Ordovician-Silurian Extinction: About 440 million years ago, this event wiped out nearly 85% of species.
Late Devonian Extinction: Occurred around 375 million years ago, affecting marine life significantly.
Cretaceous-Paleogene Extinction: About 66 million years ago, this event led to the extinction of the dinosaurs.
Climate Changes Over Millennia
The Earth's climate has changed many times over millions of years. These changes have been influenced by various factors:
Ice Ages: Periods of significant cooling that led to the expansion of ice sheets.
Greenhouse Gases: Increases in gases like carbon dioxide can lead to warming.
Solar Activity: Changes in the sun's energy output can affect the Earth's climate.
