There are different types of volcanism, but for the sake of demonstration, let's look at one type only. Volcanism can occur at convergent plate boundaries where the more dense crustal plate subducts under the less dense plate. Usually , this causes uplift and faulting in the non-subducting crust. Rising magma will find the path of least resistance in the crust, usually at these areas of faulting. Magma can be under tremendous pressure due to the expansion of trapped gasses as it rises. Once it finds an outlet to the surface, look out. It's like shaking up a bottle of soda, then opening the cap. The pressure and temperature of the quickly rising magma tears out chunks of surrounding crustal rock, widening the path leading to the release point.

What is the term for molten rock material that reaches earth's surface?
Molten rock that is contained below the earth's surface is known as magma. Once it break the surface of the earth, as in a volcanic eruption, it is called lava.
In seafloor spreading molten material rises from the mantle and erupts?
When spreading molten material rises from the mantle in the sea-floor and erupts, it can create sea mounts, which are underwater mountains. If enough material is ejected, the mounts will break through the surface of the water to create islands.
Magma reaches the earths surface as a result of the process called?
Magma reaches the Earth's surface through a process called volcanic eruption. This occurs when pressure builds up underground and forces the magma to flow and eventually break through the Earth's surface. Once the magma reaches the surface, it is then called lava.
What is the force needed to overcome intermolecular attractions and break through the surface of a liquid or spread out of the liquid?
surface tention
What are the processes that break down rock at earths surface?
Weathering and erosion are the processes that break down rock at the Earth's surface. Weathering includes physical, chemical, and biological processes that break down rocks into smaller pieces, while erosion involves the movement of these weathered materials by water, wind, ice, or gravity.

What happen to the crust when the molten rocks move upward?
When molten rocks move upward, they can break through the crust, creating volcanic eruptions and forming new landmasses. This process is part of plate tectonics where the movement of molten rock, or magma, plays a key role in shaping the Earth's surface.

What is to break through the surface of?
erupt
How spaceships get into space?
You use a spaceship and break through the earths atmosphere
What are the 4 forces that cause rocks on earths surface to break down?
Water erosion
What is processes that break down rock at earths surface?
Denudational processes, which includes, weathering, erosion, deformation, and exfoliation. Mass movement also plays a great role in changing the earths surface.
What is the part of a erosion when rocks minerals and immature soils at or near the earths surface break?
it is called a dick
Magma reaches the earths surface as a result of the process called?
Magma reaches the Earth's surface through a process called volcanic eruption. This occurs when pressure builds up underground and forces the magma to flow and eventually break through the Earth's surface. Once the magma reaches the surface, it is then called lava.
The power of endogenic and exogenic forces?
Exogenous forces are forces that work above the earths surface and break down landforms. Endogenous forces are forces that work below the earths surface and build up land forms
What can sudden forces make rocks do?
Sudden forces break the crust of the earth to make openings through which various types of material including molten magma, solid rocks, gases etc. are ejected to the surface from the interior of the earth.
What does it take for aluminum to break down?
it takes the heat of a meteorite coming through the earths atmosphere
