What is the term for the flow of magma through cracks in the earth's surface?
The term for the flow of magma through cracks in the Earth's surface is called volcanic eruption. During an eruption, magma is forced through fissures or vents onto the surface, leading to the formation of volcanic features like lava flows, ash clouds, and pyroclastic flows.
Liquid magma flow upward through the crust because it is less dence than the solid material around it?
Yes, that is correct. Magma is less dense than the solid rock around it, causing it to rise towards the surface through cracks and fractures in the Earth's crust. This movement occurs due to the buoyancy of the less dense magma compared to the denser surrounding rock.
What kind of volcano is formed when magma breaks through the crust?
That definition could apply to any volcano.
Why do volcanoes shoot up lava?
Volcanoes erupt and shoot up lava due to the buildup of pressure from molten rock, or magma, beneath the Earth's surface. As magma rises, gases dissolved in it expand, creating pressure that forces the magma upward through cracks in the Earth's crust. When the pressure exceeds the strength of the surrounding rock, it results in an explosive eruption or a more effusive flow of lava, depending on the magma's composition and viscosity. This process is driven by geological activity and the movement of tectonic plates.
What is any movement of magma inside earth?
Any movement of magma inside the Earth is called magma migration. Magma migrates due to differences in pressure, density, and temperature within the Earth's mantle, moving towards the crust through fissures or fractures. This movement can lead to volcanic activity when the magma reaches the surface.

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 an opening in the Earth's Surface through which lava can flow?
An opening in the Earth's surface through which lava can flow is called a volcano. When pressure builds up beneath the Earth's crust, it can force magma to erupt through a vent in the form of lava, gases, and ash.
Why do volcanoes shoot up lava?
Volcanoes erupt and shoot up lava due to the buildup of pressure from molten rock, or magma, beneath the Earth's surface. As magma rises, gases dissolved in it expand, creating pressure that forces the magma upward through cracks in the Earth's crust.

This process is driven by geological activity and the movement of tectonic plates.
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 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.
What is any movement of magma inside earth?
Any movement of magma inside the Earth is called magma migration. Magma migrates due to differences in pressure, density, and temperature within the Earth's mantle, moving towards the crust through fissures or fractures. This movement can lead to volcanic activity when the magma reaches the surface.
How does magma flow in an explosive eruption?
magma flows upward mixed with ash. it cools quickly when thrown up in the air and become pyroclastic blocks bombs and boulders which are the main cause of fatalities
Why magma floats to the surface?
Magma floats to the surface because it is less dense than the surrounding rock. As magma rises, its buoyancy overcomes the pressure of the rock above it, allowing it to flow upward towards the surface. The expansion of gases within the magma also helps to propel it upward.
What can allow melted rock to ooz out In a lava flow?
magma is less dense than the surrounding rock, so it is forced upward to the earth's surface
