-Crust - outer most layer 6 to 70 km

-Mantle -middle layer 71 to 2900

-Core -inner most layer 3300km

-Oceanic crust [basaltic rocks] - crusts have different density. Thickness 6 to 12 km(thin)

-Continental crust [granite rocks] - all crusts have same density. Thickness 30 to 70km(thick)

*Subduction is a process where the heavier plate sinks Benich less dense plate (1 of must be oceanic plate) sinking plate is called (slab-pull force)

-Convergence plate boundaries also known as destructive plate boundaries

divergence plates are known as constructive plates

-Tectonic plates differ in density depending on the material of crust

-The denser oceanic crust is pulled down

plates move due to the convection current in the mantle

most violent reaction when plates converge
when plates interact there is always friction and it build up energy.
seismic waves(stress released from plates movements
shallow focus- Earthquakes occurring at a depth of less than 70 km (43 mi) are classified as shallow-focus earthquakes
deep focus-All earthquakes deeper than 70 km are localized within great slabs of lithosphere that are sinking into the Earth's mantle

plates slide horizontally past each other. As the plates rub against each other, it causes huge stresses and can cause portions of the rock to break due to the fault lines in earths crust, resulting in earthquakes because of the friction when they slide past each other.

volcano practice question

(i) Mount mayon is more steeper and taller than by 1227m to Prestahnukur. Prestahnukur is much widely spread surface compared to mount mayon by 10.7km.

(ii)The volcano in Fig A is likely to be a strato volcano because it is steeper and tall as this volcanos have highly vicious lava travel slow and cool down near the crater make it become steeper overtime

I do not agree with the statement as volcanoes can form at both convergent plate and divergent plate boundaries . In convergent plate boundary volcanoes are formed particularly in subduction zones where one tectonic plate is forced beneath another. The subducted plate melts as it descends into the mantle, generating magma that can lead to the formation of volcanic eruptions as the magma contains dissolved gases which is less denser cause it to rise to the surface , resulting in the formation of a volcano over the time. Examples include the Pacific Ring of Fire, which includes the volcanoes along the western coasts of North and South America.

Also in divergent plate boundaries the volcanoes are formed at divergent plate boundaries as tensional forces pull the tectonic plates apart. As a result, fractures and faults develop in the Earth crust along the boundary. The pulling apart of the plates creates space for magma to rise from the mantle below. The magma with dissolved gases , being less dense than the surrounding solid rock, begins to move upward through the fractures and faults in the crust , resulting forming a volcano over the time.

Hence, i do not agree with the statement that volcanoes are only found near divergent plate boundaries.
