What is compressional stress?
Compressional stress is the stress produced by two tectonic plates moving towards each other.
How ring of fire related to frequent occurrence of earthquakes?
A build up of stress. As the plates move past each other or one moves under another, the edges of the plates get locked up. This is because the edges of the plates are not smooth but jagged. Eventually so much stress builds up that the plates "pop" past each other releasing a huge amount of energy in the form of an earthquake
Which occurs at a lower stress value ductile deformation or elastic deformation?
Ductile deformation is when rock is given enough stress to break. If the stress is less, it will bend but not break.
What type of stress occurs at a transform plate boundary?
shearing work
Three types of stress that occurs in Earth's crust?
Tension, Compresion, and Shear :)
What happens to lithospheric plates when an earthquake occurs?
When an earthquake occurs, lithospheric plates either slide past each other, collide, or move apart along their boundaries. The stress accumulated along the plate boundaries is released suddenly, causing the plates to deform and generate seismic waves that we feel as an earthquake.
Is it true that earthquake zones coincide with the edges of lithospheric plates?
Yes, earthquake zones often coincide with the edges of lithospheric plates because this is where tectonic plate boundaries interact. The movement and interaction of these plates can cause stress to build up and be released in the form of earthquakes.
Stick-slip motion between lithospheric plates is what causes an?
earthquake. This motion occurs when two plates along a fault line become stuck due to friction, building up stress until they suddenly slip past each other, releasing energy in the form of seismic waves.
What stress occurs when two tectonic plates collide?
When two tectonic plates collide, compressional stress occurs. This stress causes the rocks to fold and deform, leading to the formation of mountain ranges, such as the Himalayas. The intense pressure and friction between the plates can also result in earthquakes and volcanic activity.
What is a major type of stress that occurs at convergent plate boundaries?
One major type of stress that occurs at convergent plate boundaries is compressional stress. This stress is caused by the collision of two tectonic plates, leading to the plates pushing against each other and causing rocks to compress and deform, leading to the formation of mountain ranges or subduction zones.
Where rift valleys form?
A rift valley forms when the lithospheric stretches, tension stress occurs, causing rock to pull apart, break, and form normal faults.
What causes earthquake at diversion boundaries?
Earthquakes at divergent boundaries are caused by the movement of tectonic plates away from each other. As the plates separate, the stress builds up and eventually is released in the form of an earthquake. This movement can create cracks in the Earth's crust, resulting in seismic activity.
What is the stress caused by in the Earth's crust?
The grinding of tectonic plates. This caused by the outer core sending heat to the asthenosphere. The heat creates convection cells (aka convection currents), which move the asthenosphere. The tectonic, or lithospheric, plates are floating on the asthenosphere. When the asthenosphere moves, the tectonic plates move, and they gring together. The grinding will eventually cause a tectonic plate to fracture, which releases energy through the earth as seismic waves, and an earthquake occurs.
What is the stress at a divergent boundary called?
The stress at a divergent boundary is called tensional stress. This stress occurs when tectonic plates move away from each other, causing the crust to stretch and thin out.
What causes lithospheric plates to build up pressure and finally give along transform faults?
Lithospheric plates build up pressure due to the movement of the underlying mantle causing stress to accumulate along transform faults. The build-up of pressure is a result of the friction and resistance between adjacent plates. When this pressure exceeds the strength of the rocks, it causes the plates to suddenly slip past each other, resulting in an earthquake along a transform fault.
What happens when Two tectonic plates scrape across one another?
Two tectonic plates commonly scrape each other at transverse boundaries. The scraping of the plates causes a lot of tension and strain which eventually causes fault lines. When the scraping is strong enough, earthquakes are felt.
Which stress force pulls on the crust and stretches rock?
Tensional stress force pulls on the crust and stretches rock. This type of stress occurs where tectonic plates are moving away from each other.
