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.
What is the molten material moving upward within the earth's crust?
Magma
Were does magma often move upward though in the crust?
Through cracks.
Which intrusive feature may start as a sill but as more magma builds it pushes upward like a lens?
Which intrusive feature may start as a sill but, as more magma builds, it pushes upward like a lens?
Can density differences force magma upward into cooler layers on earths interior?
no
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

How are plateus formed?
Plateaus are formed by the upwelling of volcanic magma and erosion by water and glaciers. When the magma rises it causes the ground to swell upward. Large areas of flat rock are lifted up and this forms the plateaus.
Can density difference force magma upward into cooler layers of earths interior?
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.
What factors allow magma to push its way upward?
density
What is the molten material moving upward within the earth's crust?
Magma
When magma pushes sedimentary rock upward what happens?
It forms a dome.
Were does magma often move upward though in the crust?
Through cracks.
Does liquid magma rise until it reaches the surface?
yes. it goes upward through a 'pipe' that connects to the magma chamber.

What cause a quiet eruption?
Basaltic magma is forced upward in a vent
Can density differences force magma upward into cooler layers on earths interior?
no
