Why do earthquakes occur in certain areas?
GeologyWhy do so many earthquakes originate in this region? The belt exists along boundaries of tectonic plates, where plates of mostly oceanic crust are sinking (or subducting) beneath another plate. Earthquakes in these subduction zones are caused by slip between plates and rupture within plates. Why do earthquakes occur in certain areas and not everywhere?

Does Basalt tile need to be sealed?
GeologyWhile basalt rock is one of the most robust natural stone options available, it’s still necessary to seal it to protect against inevitable wear and tear. Basalt’s hard-wearing nature means it’s popular, alongside materials such as granite, for high-use areas like paving stones and kitchen surfaces. How do you seal basalt tiles? When the new
What is the diameter of the outer core?
GeologyThe outer core is very dense liquid rock (about 11 g cm−1). It is where the Earth’s magnetic field arises and has a diameter of about 6,930 km/4,300 mi. What is the diameter of the inner core? about 2,400 kilometers Composed mainly of iron, Earth’s core consists of a solid inner core about 2,400 kilometers
Can tectonic plates move quickly?
GeologyThey can move at rates of up to four inches (10 centimeters) per year, but most move much slower than that. Different parts of a plate move at different speeds. The plates move in different directions, colliding, moving away from, and sliding past one another. Most plates are made of both oceanic and continental crust.
Is Rainbow pyrite natural?
GeologyRainbow Pyrite is a cabochon stone with a natural crystal surface. Rainbow Pyrite, also known as Iridescent Pyrite, comes from Ulianovsk, Russia. It is collected on the banks of the Volga River only during the summer months when the riverbanks are less muddy. Rainbow Pyrite is considered a type of Druse. Is Rainbow pyrite rare?
