When tectonic plates under the Earth's surface shift, they create space between them. Hot rock under these plates then rises to occupy the space. As the rock rises, the pressure placed on the rock decreases and causes the rock to melt. This process occurs at the Mid-Ocean Ridge, an unde...
Cambrian period & Cambrian explosion: facts & information These bizarre sea monsters once ruled the ocean Photos: 508-million-year-old bristly worm looked like a kitchen brush In their research, the team also confirmed previous studies that found mountain formation screeched to a halt on Earth ...
With this comes the recognition that plate margins are inherently three-dimensional (3D) tectonic features, characterized by lateral variations in physical properties in both the subducting and overriding plates that may contribute to the observed deformation. For example the geophysical properties and ...

inventor is clearly invalid. “As he opines, “neither of the later approaches wholly supersedes the religious approach; rather, there has been accumulation and often admixture of the three.” He further writes, “Comte’s law of the three stages could not stand the test of facts known ...
Mountains rise when Earth's ever-shifting tectonic plates smash two landmasses together, pushing surface rocks to soaring heights. Mountains can grow for hundreds of millions of years or more — but even the loftiest ranges are born with an expiration date, as erosion from wind, water and othe...
‘Greater Somalia’. However, this hypothesis was refuted by geological data87,90, which demonstrated that, by the Late Triassic–Early Jurassic, Greater Somalia had already broken into two plates, situated far from the Indian subcontinent. Instead, an alternative explanation was proposed, the ‘...
Two facts pertain to the motion of a small mass in the gravitational potential well of large body. First, at some distance from any mass distribution, the gravitational potential must reduce to the inverse radial dependence associated with a point mass. Second, the radial force of gravity, comb...
