1: How many earthquakes occur every year around the world?
According to scientists over 3 million earthquakes occur every year around the world.
2: What is the Tectonics Theory? Explain.
Plate tectonics is a scientific theory that describes the large-scale motions of Earth's lithosphere.
3: Where do the Tectonic forces originate?
The crustal plates of the Earth are in horizontal motion. This is called continental drift colloquially, and plate tectonics in technically more precise language. This is newly won knowledge. Although the idea has been around for almost a century, it was not generally accepted until the last few decades.
4: What are Earth’s 3 main layers?
The core, the mantle, and the crust are the Earth's 3 main layers.
5: Where is Tectonic activity concentrated?
They tend to be concentrated in narrow zones because the plate tectonics tells us that the Earth's rigid outer shell (lithosphere) is broken into a mosaic of oceanic and continental plates which can slide over the plastic aesthenosphere, which is the uppermost layer of the mantle. The plates are in constant motion. Where they interact, along their margins, important geological processes take place, such as the formation of mountain belts, earthquakes, and volcanoes.
6: What is the Lithosphere? Where is it located?
The tectonic plates are made up of Earth’s crust and the upper part of the mantle layer underneath. Together the crust and upper mantle are called the lithosphere and they extend about 80 km deep.
7: What is the Asthenosphere? Why is it important to plate tectonics?
The Asthenosphere is a layer of the earth crust that is very soft and changes form with changes in temperature. The Asthenosphere is what carries the mass of the continents and the lithosphere on its back.
8: How fast do plates move (average?)
The usual movement that ectonic plates move is 0 to 100 mm per year.
9: What are the 3 types of plate boundaries?
There are three kinds of plate tectonic boundaries: divergent, convergent, and transform plate boundaries.
10: What happens at Divergent Boundaries? Where are these mostly located?
Divergent boundaries occur along spreading centers where plates are moving apart and new crust is created by magma pushing up from the mantle. Picture two giant conveyor belts, facing each other but slowly moving in opposite directions as they transport newly formed oceanic crust away from the ridge crest.
