Why does magma in the mantle rise through the crust above it?
magma comes from the outer core and when an earthquake or something happends, a crack froms and the pressure of lava shoots up like a geyser.
What causes it to erupt?
Sometimes the plates on the earths crust crash into each other, forcing one to go lower. The friction causes the rock to get hotter and hotter until it melts. This is called magma. The magma keeps getting hotter, but it needs somewhere to go, so it surges up through the earths crust, making a hole. That is how a volcano is made. Once the hole is made, magma from the earths core comes to the surface, causing the volcano to spit lava
How magma turns into lava?
its just lava when it reaches earth's serface, its magma when its still inside Molten rock on the surface is called lava. It is cooler than magma, and quickly becomes solid. This is because it is much cooler on the earths surface than inside the earth. As magma rises it starts to cool, as you go up the volcano it gets cooler by 15 degrees every 1 km. so when the magma gets to the top of the volcano it is cooled down quite a bit and turns into lava
How does magma go into a volcano?
Being a less dense liquid, it rises toward the surface, seeking the path of least resistance. The volcano is simply a structure created by the rising magma and the surface features of its lava.
Why does molten rock from the mantle come to the surface at the mid-ocean ridges?
Molten rock, or magma, rises to the surface at mid-ocean ridges due to the process of mantle convection. Hot rock from the Earth's mantle rises towards the surface, creating pressure that can cause melting. This molten rock then escapes through cracks in the Earth's crust at mid-ocean ridges, leading to the formation of new oceanic crust.

What happens when you go further into the earths crust?
you get hotter and hotter

How the oceanic crust move?
The earths crust layer is constantly moving because of the layer beneath it that has all the liquid magma. The magma needs a place to escape because of the pressure it takes on so where does it go, it goes up and pushes on the earths crust to escape. The places it escapes are pretty much where they follow the path of least resistance and that is where the plates of the earth crust meet. The Atlantic ridge which is the second biggest in the world has eruptions all the time constantly added to land to the sea and pushing other plates together. So in short the plates move because the layer beneath it are always on the move as well.

Where does the oceanic crust eventually go?
It is subducted toward the core and eventually melts, forming magma.
How does the natural volcano occur?
First, the magma deep under the Earth's crust, builds up & when it builds up, Earth's crust builds up as well. It takes a while for the magma to finally overflow & burst out of the Earth's crust, & if we didn't have crust to surround the magma, researchers say that lava could cover at least half our World! It seems crazy, but it is possible. There you go. Enjoy.
How do volcanoes add new material go the earths surface?
Volcanoes add new material to the Earth's surface primarily through the eruption of magma, which is molten rock from beneath the Earth's crust. When magma rises and erupts, it can solidify into various forms of volcanic rock, such as basalt or pumice. Additionally, volcanic ash and other materials are released during eruptions, contributing to new landforms. Over time, repeated eruptions can build up volcanic mountains and islands, significantly altering the landscape.
What causes the pressure to increase as you go deeper below the earths crust?
Because the density of the force increases.
What earth changing processes is responsible for mountains?
It occurs when tectonic plates or different sections of the earths crust push together and over millions of years eventually create a mountain range. Basically they have no where else to go but up. It is caused by convection currents in the magma below
