Convection. Hotter equals rarer, colder equals denser. So the warmer material in the lower mantle and outer core rises through the cooler material in the outer mantle toward the crust, while the cooler material falls towards the core. They then cool and heat up respectively, and change positions. They then cycle around heating and cooling, rising and falling.
Magma from deep inside the Earth rises toward the surface because of its lower density compared to the surrounding rocks, creating buoyancy forces that drive the magma upwards. Additionally, the pressure from gases within the magma can also contribute to its ascent.
FALSE: gravity cannot force magma upwards, gravity can olny force downwars. the reason magma shoots from the earths interior is because the pressure from the magma trying to push through the force gravity causes an eruption.
Yes, magma tends to rise towards the earth's surface. It does so because once melted it becomes less dense.
Magma rises from the asthenosphere to the surface of the Earth. After it reaches temperature upward to 1000 degrees Fahrenheit, the magma starts to rise. Gases also aid in pushing the magma toward the surface, along with the tremendous pressure from the depth at which it originates.
Mountains formed by magma that reaches the Earth's surface are called volcanoes.
Because magma is less dense than the surrounding solid rock, it is forced upward toward the surface. When magma reaches the surface and flows from volcanoes, it is called lava.
in the mantle above the slab
The inside of the earth (Mantle) pushes the hot magma liquid and makes the magma move toward the surface.
The tectonic plates push together thus causing magma to shoot up and rise hence an eruption

Magma that reaches the Earth's surface is known as lava.
Magma once it reaches the earths surface is called lava.
Magma that reaches earth's surface is called lava.
Lava.

Lava. Note: Magma cant erupt, volcanoes do. Magma is just the word for molten rock beneath the earths surface, lava is for molten rock above the earths surface.
Magma is less dense than the surrounding rock; as such, it will rise toward the surface.
