What two plates caused the Nepal earthquake?
Regional SpecificsCauses. On a 7.8 earthquake struck Nepal in Asia. The earthquake occurred on a convergent collision plate boundary between the Indian and Eurasian plates. The focus was only eight kilometres deep and the epicentre was just 60 kilometres north-west from the capital Kathmandu. What were the two plates that caused the earthquake? Tectonic Plate Boundaries

What type of rock is lava?
Regional SpecificsExtrusive Igneous Rocks: These are the rocks that form at erupting volcanoes and oozing fissures. The magma, called lava when molten rock erupts on the surface, cools and solidifies almost instantly when it is exposed to the relatively cool temperature of the atmosphere. What type of rock is lava rock? extrusive igneous rocks When lava

How does paleomagnetism prove continental drift?
Regional SpecificsPaleomagnetists led the revival of the continental drift hypothesis and its transformation into plate tectonics. Apparent polar wander paths provided the first clear geophysical evidence for continental drift, while marine magnetic anomalies did the same for seafloor spreading. What is paleomagnetism and how does it provide evidence for plate tectonics? Paleomagnetism also provides evidence to
