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 earth rises toward the surface because?
Because magma is less dense than surrounding solid rock, so it is forced upward toward the surface.
Why does Magma tends to rise toward the Earth's surface?
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.
Magma tends to rise toward earths surface?
Yes, magma tends to rise towards the earth's surface. It does so because once melted it becomes less dense.
Mountains formed by magma that reaches the Earths surface are?
Mountains formed by magma that reaches the Earth's surface are called volcanoes.
Magma that has reached the earths surface?
This name is lava.
Could property of magma that cause it to be forced upward towards earth surface?
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.
Magma from deep inside earth rises toward the surface because?
Because magma is less dense than surrounding solid rock, so it is forced upward toward the surface.
How magma moves upward though a volcano and reaches the surface during an eruption?
The inside of the earth (Mantle) pushes the hot magma liquid and makes the magma move toward the surface.
Where does magma form before it moves toward the earths surface?
in the mantle above the slab
Why does Magma tends to rise toward the Earth's surface?
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.
What causes magma to flow upward thought the earths surface?
The tectonic plates push together thus causing magma to shoot up and rise hence an eruption
Magma tends to rise toward earths surface?
Yes, magma tends to rise towards the earth's surface. It does so because once melted it becomes less dense.
What term refers to magma at the earths surface?
Magma once it reaches the earths surface is called lava.
What is the magma when it reaches the earths surface?
Magma that reaches the Earth's surface is known as lava.
What is the name for lava before it leaves the volcano?
its magma before it reaches earths surface. lava is when its at earths surface
Magma that reaches the earths surface?
Magma that reaches earth's surface is called lava.
Can density differences force magma upward into cooler layers on earths interior?
no
