How are tsunamis earthquakes and tectonic plate movement related quizlet?
Stress makes rock and earth's surface move. The large movement cause earthquakes and earthquakes cause landslide and or ocean floor uplift which cause tsunamis.
How tsunamis and earthquakes are related?
Most tsunami are caused by large earthquakes on the sea floor when slabs of rock move past each other suddenly, causing the overlying water to move. The resulting waves move away from the source of the earthquake event.
How are earthquakes and plate tectonics related?
Earthquakes occur along fault lines, cracks in Earth's crust where tectonic plates meet. They occur where plates are subducting, spreading, slipping, or colliding. As the plates grind together, they get stuck and pressure builds up. Finally, the pressure between the plates is so great that they break loose.
Is there a relationship between plate boundaries and the location of tsunamis?
Convergent boundaries are the big culprits. When one plate is forced to dive beneath another plate, there is no way to do it except with some component of vertical motion. The cartoon below shows how an earthquake at a convergent boundary (subduction zone) creates a tsunami.
What happens to the tectonic plates along a transform boundary during the time between an earthquake?
DESCRIBE what happens to the tectonic plates along a transform boundary at the moment when an earthquake occurs. The plates suddenly slide past each other in opposite directions. Tectonic plates along transform faults bind, causing pressure to build up over time.
What happens to the tectonic plates along a transform boundary between an earthquake?
The third type of plate boundary occurs where tectonic plates slide horizontally past each other. This is known as a transform plate boundary. As the plates rub against each other, huge stresses can cause portions of the rock to break, resulting in earthquakes. Places where these breaks occur are called faults.
How do tectonic plates cause tsunamis?
Earthquakes that generate tsunamis most often happen where Earth's tectonic plates converge, and the heavier plate dips beneath the lighter one. Part of the seafloor snaps upward as the tension is released. The entire column of seawater is pushed toward the surface, creating an enormous bulge.
What are tectonic earthquakes?
Tectonic earthquakes are produced by sudden movement along faults and plate boundaries. Earthquakes induced by rising lava or magma beneath active volcanoes is called volcanic earthquakes.
How are earthquakes and volcanoes related to the theory of plate tectonics?
When these plates move around, they collide, move apart, or slide past each other. The movement of these plates can cause vibrations known as earth- quakes and can create conditions that cause volcanoes to form. and earthquake epicen- ters are related to tectonic plate boundaries.
What type of tectonic plate movement causes earthquakes?
About 80% of earthquakes occur where plates are pushed together, called convergent boundaries.
Which type of plate tectonic movement is associated with tsunamis?
convergent plate boundaries Most large tsunamis occur at convergent plate boundaries where two tectonic plates are crashing into each other. As the two plates collide one plate is forced down underneath the other.
What causes a tsunami?
A tsunami is a series of extremely long waves caused by a large and sudden displacement of the ocean, usually the result of an earthquake below or near the ocean floor. This force creates waves that radiate outward in all directions away from their source, sometimes crossing entire ocean basins.
What is the relationship of plate tectonics with earthquakes volcanoes and mountain ranges?
When these plates move around, they collide, move apart, or slide past each other. The movement of these plates can cause vibrations known as earth- quakes and can create conditions that cause volcanoes to form. and earthquake epicen- ters are related to tectonic plate boundaries.
What type of earthquake occurs when two tectonic plates move suddenly against each other?
The earthquakes that occur along these zones, called spreading centers, are relatively small. The Great Rift Valley in Africa, the Red Sea and the Gulf of Aden all formed as a result of divergent plate motion. Convergent (Colliding): This occurs when plates move towards each other and collide.
How are tsunamis formed?
A tsunami is a series of extremely long waves caused by a large and sudden displacement of the ocean, usually the result of an earthquake below or near the ocean floor. This force creates waves that radiate outward in all directions away from their source, sometimes crossing entire ocean basins.
What causes the tectonic plates to move?
The plates can be thought of like pieces of a cracked shell that rest on the hot, molten rock of Earth's mantle and fit snugly against one another. The heat from radioactive processes within the planet's interior causes the plates to move, sometimes toward and sometimes away from each other.
Do all earthquakes produce tsunamis Why or why not?
Not all earthquakes generate a tsunami. To generate tsunamis, earthquakes must occur underneath or near the ocean, be of a large magnitude, and create vertical movement of the sea floor. Generally, earthquakes on strike-slip faults, such as the San Andreas, do not by themselves generate tsunamis.
What is the relationship between volcanoes earthquakes and tsunamis in Asia How do seismic events like earthquakes cause tsunamis?
Tsunamis are usually triggered by earthquakes, volcanic eruptions and underwater explosions, landslides and other mass movements. Underseas earthquakes have generated nearly all the major tsunamis in history. Tsunamis can be generated when the sea floor abruptly deforms and vertically displaces the overlying water.
What causes earthquakes and at what types of plate boundaries are earthquakes common explain?
About 80% of earthquakes occur where plates are pushed together, called convergent boundaries. Another form of convergent boundary is a collision where two continental plates meet head-on. Since neither plate is stronger than the other, they crumple and are pushed up.
What plate boundary causes tsunamis?
convergent plate boundaries Most large tsunamis occur at convergent plate boundaries where two tectonic plates are crashing into each other. As the two plates collide one plate is forced down underneath the other. As this happens the leading edge of the top plate snags on the bottom plate and pressure starts to build.
What type of earthquake causes a tsunami?
Most tsunamis are generated by earthquakes with magnitudes over 7.0 that occur under or very near the ocean and less than 100 kilometers (62 miles) below Earth's surface (earthquakes deeper than this are unlikely to displace the ocean floor).
What causes tsunamis to happen?
A tsunami is a series of extremely long waves caused by a large and sudden displacement of the ocean, usually the result of an earthquake below or near the ocean floor. This force creates waves that radiate outward in all directions away from their source, sometimes crossing entire ocean basins.
What causes earthquakes?
The tectonic plates are always slowly moving, but they get stuck at their edges due to friction. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and cause the shaking that we feel.
What is the relationship between locations of earthquakes and plate tectonics quizlet?
What is the relationship between locations of earthquakes and plate tectonics? A. Earthquakes frequently happen where landmasses are on the boundary between two plates.
How does the movement of tectonic plates cause earthquakes and volcanoes?
Where plates come into contact, energy is released. Plates sliding past each other cause friction and heat. Subducting plates melt into the mantle, and diverging plates create new crust material. Subducting plates, where one tectonic plate is being driven under another, are associated with volcanoes and earthquakes.
What causes tectonic plates to move?
The plates can be thought of like pieces of a cracked shell that rest on the hot, molten rock of Earth's mantle and fit snugly against one another. The heat from radioactive processes within the planet's interior causes the plates to move, sometimes toward and sometimes away from each other.

What happens when tectonic plates move?
When the plates move they collide or spread apart allowing the very hot molten material called lava to escape from the mantle. When collisions occur they produce mountains, deep underwater valleys called trenches, and volcanoes.
