It dries then if other magma goes in the same direction as the old magma it sometimes reheats it then it flows toward the surface

What are mountains formed by magma that reach the Earth's surface?
Mountains formed by magma that reach the Earth's surface are called volcanic mountains or ridges.
What is openings in Earth's crust that allows magma to reach the surface called?
The opening of the crust where magma is allowed to reach to the surface is called a fault line.
What are openings in the earth's crust that allow magma to reach the surface?
Volcanoes
When does magma reach Earth's surface and become lava?
when it reaches land
What is the opening in the earth's crust that allows magma to reach the surface?
Vents
Does magma always reach the Earth's surface?
no sometimes it cools under earth's surface. that is called intrusive igneous rocks. when it reaches earth's surface and cools its called extrusive igneous rocks.
What natural phenomenom occurs when magma breaks through the earth crust?
A lava flow may flow over the surface from a fissure deep enough to reach the magma layer. Or, if under pressure, an eruption from a volcano.
What is molten rock that is outside of the earth?
Below the surface, the molten rock is called magma; at the earth's surface it becomes lava, nothing has changed only the name of the liquid. Igneous rock is made by fire. Small wonder the magma from which igneous rock is formed can reach temperatures close to 1200 degrees Celsius.
How does magma reach the top of a volcano?
Pressure inside the earth forces the magma through cracks and other conduits in earth's crust.
What type of landform is CREATE when to oceanic plates pull away from each other?
Since the plates pull apart from each other, a volcano is formed. Magma will push its way up through the cracks found between the plates onto the Earth's surface. The magma reaches the Earth's surface as lava. Lava and magma are made of the same substance. The process by which magma and other materials reach the Earth's surface is called vulcanicity. The outpouring of the lava to the surrounding areas is called an eruption. This is caused by the build-up pressure caused by gases below the Earth's surface. The magma may flow out onto the Earth's surface quietly or be accompanied by violent eruptions. The lava hardens on the Earth's surface as the temperature is cooler. The hardened lava built up from many eruptions results in a cone-shaped mountain called a volcano. Hope it helped :)
Why magma rise toward the surface?
Magma is less dense than rock and is buoyant due to this density difference. It will seek out any weaknesses in the rock above it to reach the surface.
How do volcanoes erupt on the Earth's surface?
A rising plume of liquid rock (also known as magma) can reach the surface from the underlying mantle. There are also volcanoes which explode due to the pressure of water vapor, when porous rocks contain water, and these rocks are heated by magma. Those are called boiler volcanoes.
