The opening in Earth's crust through which magma rises to the surface is known as the?
The opening in the earth crust which magma rise to the surface are Volcanoes
Why does magma rise to the crust above it?
Magma rises through the crust above it because of pressure and depending on the magma (Pahoehoe or Aa). Pahoehoe is thin and runny and pours outside of the crust but, Aa is think and chunky and it can not pour out of a crack in the crust. It is more likely to blow out.
What is a narrow almost vertical crack in the crust that magma rises to the surface through?
eruption
What boundary is formed when magma rises to the surface and new crust is formed?
A divergent boundary is formed when magma rises to the surface and new crust is formed. This process occurs at mid-ocean ridges where tectonic plates move away from each other, allowing magma to fill the gap and solidify into new oceanic crust.
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.
Why does magma in the mantle rise through the crust above it?
magma comes from the outer core and when an earthquake or something happends, a crack froms and the pressure of lava shoots up like a geyser.
What process makes new crust when the sea floor moves apart and magma rises up?
The process that makes new crust when the sea floor moves apart and magma rises up is called seafloor spreading. Magma from the mantle rises to the surface at mid-ocean ridges, cools, and solidifies to form new crust as the tectonic plates move apart. This process contributes to the continuous growth of the seafloor and the expansion of the ocean basins.
The hot liquid rock that rises from deep within the earth is called ?
Magma if it's beneath the crust, lava if it's above the crust
What seafloor is the process by which new crust is created when seafloor moves apart and magma rises?
Seafloor Spreading
What is a hole or crack in the earth's crust through which magma rises to the surface called?
It is called a volcano.
What is called when new crust forms where magma rises at mid ocean ridges?
sea floor spreading
Which term best describes the location where magma rises to earths surface and flows out of an opening in the crust?
Volcanoes
