Where is the outer most layer of the earth the thinnest?
ocean valleys...
How do plate tectonics causes earthquakes?
The concept of plate tectonics has revolutionized the explanation about how earthquakes occur in Earth Sciences. 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.
What is the liquid layer of the earth's core?
The layer of the earth in liquid form is the mantle. It is made up of magma and lies directly beneath the earth's crust. This liquid is responsible for moving continents and earthquakes. It is the thickest layer of the earth.
How does the structure of the earth help explain why earthquakes and volcanoes occur along lines?
well basically because of the sphere shape of the earth the inner layers such as the mantle, inner core outer and crust the volcanoes will always grow in the direction of the sun because they are like plants and need sunlight to keep them alive, there fore all volcanoes will get there sun because of the rotation of the earth. Thank you i hope i helped.
Why the earth's inner core spins faster than the outer earth?
My rough guess is that "faster (inner) core is relic of tidal deceleration." Since tidal deceleration of the Earth is due to frictional force exerted by ocean tide on the ocean bottom surface, core can decouple in the tidal braking. (sunghona@kasi.re.kr)
What is the name of the outer most layer of the Earth where earthquakes occur?
This is known as the Lithosphere.
The outer most layer of the earth where earthquakes occur?
This is known as the Lithosphere.
What are the giant pieces of earth outer layer where most earthquakes occur called?
tectonic plates
Which layer of the earth is most affected by an earthquake?
Earthquakes occur in the crust (solid rock) layer.
Most earthquakes occur along the edges of?
Most earthquakes occur at the boundaries of tectonic plates. And i think Most earthquakes occur along the edge of the oceanicand continental plates. The earth's crust (the outer layer of the planet) is made up of several pieces, called plates. The plates under the oceans are called oceanic plates and the rest are continental plates. The plates are moved around by the motion of a deeper part of the earth (the mantle) that lies underneath the crust. These plates are always bumping into each other, pulling away from each other, or past each other. The plates usually move at about the same speed that your fingernails grow. Earthquakes usually occur where two plates are running into each other or sliding past each other. I think so.
Why are earthquakes described as earth shattering?
Earthquakes occur due to brittle failures in the Earth's lithosphere. Brittle failures occur where fractures propagate through the material. So an earthquake is literally the consequence of fracturing or shattering a part of the brittle outer layer of the earth. It could also be argued that they "shatter" the lives of the people affected by them.
Do earthquakes have to do with astronomy?
absolutely nothing. astronomy has to do with outer space and planets. While earthquakes would be geology
Does an earthquake occur only in continental crust?
No, earthquakes can occur anywhere in the crust, oceanic crust or continental crust. An earthquake occurs when the hard brittle solid material of the crust fractures under stress. Earthquakes cannot occur deeper than the crust (the mantle is plastic and flows slowly under stress instead of fracturing, the outer core is liquid and flows even easier than the mantle).
How did you discover that the outer core was liquid?
It was observed that p (pressure) waves from earthquakes passed through the core bus s (sheer) waves from earthquakes did not.
In what ocean would you be swimming in if you were in the Outer Banks North Carolina?
The Atlantic Ocean.
In what ocean would you be swimming if you were in the Outer Banks North Carolina?
The Atlantic Ocean.
Do earthquakes occur beneath the surface of the earth?
The largest deep earthquake struck June 9, 1994 in Bolivia with a magnitude of 8.2 and a depth of 647km. Most quakes at this depth are of much lower magnitude. For example the USGS site shows some deep quakes in the Fiji region over the past few days around 600km deep with magnitudes of 5.0 and under.
