How Do Volcanoes Erupt? | Class 8 - Geography | Learn With BYJU'S

What if I told you that our Earth is like a pressure cooker? It is actually true. Just like a pressure cooker has a vent that allows excess steam to come out, Earth has its own vents and they are called ‘volcanoes’. Deep inside the Earth temperatures are so high that some rocks start melting and it becomes a thick flowing substance called ‘Magma’. It then rises up, eventually causing the volcano to erupt. But, how and why does it rise up? When does Magma become lava? Watch this video and find out all about volcanoes and how they erupt.
What do you think happens during an earthquake? Let us know in the comment section below.

Thank you mam

[@rituarya5819]

Mam pls tell why there is more pressure created due to melting of lithospheic plates??

[@eruptionat9th131]

Firstly, lithospheric plate is not melt .. and the pressure is not created..
= There is flowing of magma inside the lithospheric plate/crust the heat of magma creats pressure or convectional current (this you read in class 9th)....
Because of heat of magma pressure creats crack between the lithospheric plate that generates volcano eruption 🌋 ...

[@snehamenon6919]

Volcano

[@su_v]

An earthquake is caused by a sudden slip on a fault. ... 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 so!

[@Mau273_]

The boring study became fun

[@raghavsharma4466]
