Earth’s surface is the “living skin” of our planet — it connects the physical, chemical, and biological systems. Over geological time, landscapes change as this surface evolves, regulating the carbon cycle and nutrient circulation as rivers carry sediment into the oceans. All these interactions have far-reaching effects on ecosystems and biodiversity — the many living ...
Geology is an amazing subject. Especially now when so much is happening around the world in terms of volcanic eruptions and seismic activities. Let’s review how the interior of the Earth is structured. We’ll take a journey into the depths of the Earth, down through the crust and mantle, nearly to the core. We’ll use ...
Let’s take a journey into the depths of the Earth, down through the crust and mantle nearly to the core. We’ll use seismic waves to show the way, since they echo through the planet following an earthquake and reveal its internal structure like radar waves. Down near the core, there are zones where seismic waves ...
