I believe the temperature gradient underground is as high as 30°C per kilometer of depth. Thus, it is very warm only 1 kilometer below the Earth’s surface. Yet, it is commonly stated that geothermal …

Quoting a sign in Redwood National Park: Redwoods once covered large expanses of the world. Millions of years ago some of these redwoods were preserved as fossilized trees when volcanic ash buried …

Mount Elbrus, in the Caucasus region of Russia, 65 km southwest from Kislovodsk, is a major, isolated volcano in the heart of a continent-continent collision zone. It is not normal for volcanoes to …

Reading a course on Precambrian, I read that: Earth Age (around 4.5 billion years) is dated thanks to the meteorites hitting Earth during its formation rather than the inner materials composing the …
|
The standard representation of the rock cycle usually looks like this: Does each stage of the rock cycle currently balance? That is, are the various processes in dynamic equilibrium, so that the …
|
Most of the water cycle studies focus on the processes and changes occurring over land with little emphasis on the ocean. Meanwhile, the ocean covers almost 3/4 of the surface of Earth. How much of …

No known hurricane has ever crossed the equator. Hurricanes require the Coriolis force to develop and generally form at least 5° away from the equator since the Coriolis force is zero there. Are …
