What is the term for the flow of magma through cracks in the earth's surface?
the flow of magma in eath's crust is called lava.
Does lava flow to the surface and become a magma?
No. Magma flows to the surface and becomes lava.
What is a geologic situation in which a magma does not form a lava?
Lava is simply magma that reaches the surface of the earth. If a magma flow never is emergent while it is still in liquid form, it cannot be termed lava. An example is a volcanic stock or a laccolith that remains beneath the surface entirely.
How does lava leave a volcano?
Magma inside Earth is under a lot of pressure, so it will tend to flow toward the lower pressure at the surface. Additionally, gasses dissolved in the magma bubble out of the magma as it approaches the surface, like bubbles from a freshly opened can of soda. As the gases expand they forces some of the molten rock out of the volcanic vent.
What can erupt to bring a lava flow to earths surface?
magma

Is lava the magma flow out onto Earth's surface?
yes
Does lava flow to the surface and become a magma?
No. Magma flows to the surface and becomes lava.
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
What process causes liquid rock to move?
Vulcanism is the process that forces liquid rock (magma) from deep within the Earth, up to the surface. Once the rock is expelled from a Volcano, the force of Gravity makes it flow down the sloped surface.
What causes hot spots on earth?
The flow of molten magma is what causes varying hot spots on Earth. Hot spots are also known to heat water beneath the ground.
What is the force that move the Earth's plates?
The force that causes most of the plate movement is thermal convection, where heat from the earth's interior causes currents of hot rising magma and cooler sinking magma to flow, moving the of plate the crust along with them.
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 explains the movement of the earth's crust?
The earth's crust moves because the earth has tectonic plates that move because the magma under the earth's surface is constantly boiling. Since the water moves, it causes the earth's crust to move.
