Does Magma push towards the Earth's surface through cracks?
Yes, magma pushes towards the Earth's surface through cracks in the crust, a process known as volcanic activity. When pressure builds up beneath the surface, magma can force its way through weak points in the crust, such as fractures or faults, leading to volcanic eruptions.
Were does magma often move upward though in the crust?
Magma often moves upward through the Earth's crust along cracks and fractures in the rock, known as magma conduits. These conduits can be created by tectonic activity, such as the movement of tectonic plates, which can provide pathways for magma to reach the surface and form volcanic eruptions.
Which formation occurs when magma pushes all the way through the exterior of the earths crust?
volcanic mountain
Why does magma rise through the crust above it?
Magma rises through the crust due to differences in density between the magma and surrounding rock. Magma is less dense than the solid surrounding rock, so it moves upwards through cracks and fractures in the crust. As it rises, magma can also be driven by pressure differences and heat from the Earth's mantle.
When magma reaches the exterior of the Earths crust is becomes?
Lava
How does magma rise to the surface of the Earth?
Through cracks, holes or vents in the earths crust.
Magma that breack through the earths curst is called?
Once magma breaks through the earths crust it is called"lava"

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.
Were does magma often move upward though in the crust?

How does the silica content of earths crust under the oceans get magma?
Silica-rich magma forms in mid-ocean ridges due to partial melting of the upper mantle, as a result of increased temperature and decreased pressure. This magma rises through cracks in the oceanic crust and can eventually erupt at the surface as lava.
Which formation occurs when magma pushes all the way through the exterior of the earths crust?
volcanic mountain
How does tectonic plate motion relate to volcanoes?
A volcano is magma that has come through the earth's crust through cracks created by movement of the plates.
What is the effect of actions of magma in the earths crust?
It is from the Volcano
What is magma that has escaped from the earths crust called?
Lava!
Why does magma rise through the crust above it?
Magma rises through the crust due to differences in density between the magma and surrounding rock. Magma is less dense than the solid surrounding rock, so it moves upwards through cracks and fractures in the crust. As it rises, magma can also be driven by pressure differences and heat from the Earth's mantle.
How do volcanoes takes place?
Volcanoes are essentially holes in the earths surface through which magma and lava can erupt. when pressure builds up below the earths crust, magma is then forced violently out of the volcanoes.
