The boundary where the two plates meet is called a convergent boundary. Deep trenches appear at these boundaries, caused by the oceanic plate bending downward into the Earth. Deep below the Earth ...

Earth's continents are slowly moving across the planet's surface due to plate tectonics, culminating in regions of crustal ...

Earth's surface is a turbulent place. Mountains rise, continents merge and split, and earthquakes shake the ground. All of ...

Continental plates are usually quite thick (between 35 to 70 km) compared to the much thinner oceanic plates (between 5 and 10 km). The oceanic rocks are usually made from basalt, while ...

For example, oceanic plates are denser than the continental plates. The eggshells do not move while the plates do. The egg has one inner section (yolk) whereas the Earth's core comprises a solid ...

plus the understanding that plates' movement caused earthquakes, Alfred Wegener's idea of "continental drift" looked less ludicrous than his contemporaries had thought. There still seemed to be no ...
