The main reason why the tectonic plates move is the conversational currents. There is magma between the upper mantle and the asthenosphere that heats up at the upper mantle. The weight is so small that the magma rises with the help of these conversational currents. When the magma has ascended towards the asthenosphere, it has nowhere to go so the magma lies along the asthenosphere. There the magma cools down again because the asthenosphere is colder than the upper mantle, which makes the magma heavier and goes back down to the upper mantle, where the magma heats up again and everything starts all over again and so it goes on over and over again. Scientists have concluded that the earth's gravity causes two other processes that also cause the tectonic plates to move.
Ridge push - in the spreading zones, the sides of the tiles are raised and slide to the side as in a slide.
Slab pull - when a plate is pulled down by gravity in a subduction zone like an anchor.
Answer:
A language family is a group of related languages that developed from a common historic ancestor, referred to as protolanguage (proto– means 'early' in Greek). ... Further back in time, all these ancestral languages descended, in turn, from one common ancestor. the most popular languge family is Indo-European
Answer:
Europe can be considered as a cultural region.
Explanation:
Europe is part of the Eurasian continent. It has been defined as a separate continent not as all others, but on the basis of culture, religion, and race. While this may come as strange, it is not actually, as almost all ethnic groups are descended from the Aryans, speak Indo-European languages, and follow the same religion (Christianity).
These traits put Europe on the map as a cultural region. Not to be confused though, as these are all general traits, which is in contrast with the high amount of different cultures, languages, and religious fractions throughout Europe. While the continent as a whole can be defined as a cultural region, it has to be mentioned that there are also smaller ethnic groups like the Magyars, Szekely, Finns, Basques, Tartars, etc. that come from different cultural, ethnic, and in some cases religious backgrounds.
