because the planet’s crust is broken into 17 major‚ rigid tectonic plates that float on a hotter‚ softer layer in the Earth’s mantle.[1] Therefore‚ on Earth‚ volcanoes are generally found where tectonic plates are diverging or converging. For example‚ a mid-oceanic ridge‚ such as the Mid-Atlantic Ridge‚ has volcanoes caused by divergent tectonic plates pulling apart; the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates coming together. Volcanoes can also form where there is stretching

There have been a couple supercontinents in the past. Three of them confirmed. The first of three is Rodinia. The second is Pannotia‚ and the third and most recent is Pangaea. These obviously aren’t here anymore and there won’t be another for a long time. From 50 million years to 200 million years. Could this actually happen again? The answer is yes. What even are supercontinents? One wouldn’t know if it could happen again if they don’t know what it is. Well‚ a supercontinent is several land

Deductive reasoning is a basic form of valid reasoning. Deductive reasoning‚ or deduction‚ starts out with a general statement‚ or hypothesis‚ and examines the possibilities to reach a specific‚ logical conclusion. In deductive reasoning‚ if something is true of a class of things in general‚ it is also
Premium Plate tectonics Earthquake
Most naturally occurring earthquakes are related to the tectonic nature of the Earth. Such earthquakes are called tectonic earthquakes. The Earth’s lithosphere is a patchwork of plates in slow but constant motion caused by the release to space of the heat in the Earth’s mantle and core. The heat causes the rock in the Earth to flow on geological timescales‚ so that the plates move slowly but surely. Plate boundaries lock as the plates move past each other‚ creating frictional stress. When the

The theory of plate tectonics According to the generally accepted plate-tectonics theory‚ scientists believe that Earth’s surface is broken into a number of shifting slabs or plates‚ which average about 50 miles in thickness. These plates move relative to one another above a hotter‚ deeper‚ more mobile zone at average rates as great as a few inches per year. Most of the world’s active volcanoes are located along or near the boundaries between shifting plates and are called plate-boundary Volcanoes
