A forms when magma slowly rises up inside the crater of a larger volcano.?
When magma slowly rises up the inside the crater of a larger volcano, it forms a Lava Dome.
What forms when magma slowly rises up inside the crater of a larger valcao?
A large lava dome can be formed when magma slowly rises up inside the crater of a larger volcano. It is a roughly circular mound shaped protrusion resulting from explosion of lava from the volcano.Ê
Why does magma rise slowly through the mantle?
The viscosity (resistance to runniness) of magma affects the rate at which it rises up through the mantle. High viscosity magma rises slowly because it's thick and sticky, and low viscosity magma rises quickly (like the big island of Hawaii). Low viscosity magma is less likely to erupt explosively because it has less chance to build up pressure. High viscosity magma is the opposite and a lot of pressure has to build up before it will erupt, which causes a more explosive/sudden eruption.
Which forms inside the crater of a large volcano?
A caldera may form inside the crater of a large volcano. A caldera is a large depression caused by the collapse of the summit of the volcano following a massive eruption. It can be several kilometers in diameter.
Why magma rise soon after it forms?
Magma rises soon after it forms because it is less dense than the surrounding solid rock. The less dense magma is buoyant and is able to move upwards through cracks and fractures in the Earth's crust. This process of magma rising is driven by the pressure differences between the magma chamber and the surrounding rocks.

Where one tectonic plate is pushed under another magma forms and rises toward the surface form where the magma erupts as lava that builds up?
valcano
How does the magma rise from the volcano?
magma rises up out of a volcano by the build up of pressure
Why does magma rise slowly through the mantle?
The viscosity (resistance to runniness) of magma affects the rate at which it rises up through the mantle.

High viscosity magma is the opposite and a lot of pressure has to build up before it will erupt, which causes a more explosive/sudden eruption.
Why does pressure in magma build up as it rises toward the surface?
Pressure in magma builds up as it rises toward the surface because the weight of the overlying rock increases, causing the magma to be squeezed and pressurized. This pressure can eventually lead to volcanic eruptions.
What is the process by which new crust is created when the seafloor moves apart and magma rises up?
This process is called seafloor spreading. It occurs at divergent plate boundaries where tectonic plates move apart. Magma rises up from the mantle through the cracks, solidifies upon contact with the cold seawater, and forms new oceanic crust.

A caldera may form inside the crater of a large volcano. A caldera is a large depression caused by the collapse of the summit of the volcano following a massive eruption. It can be several kilometers in diameter.
What forms when cold water mixes with hot volcanic magma?
This depends on the amount of water and magma, their location, and speed of contact. Magma that cools slowly within a magma chamber usually ends up forming bodies of plutonic rocks such as gabbro, diorite and granite, depending upon the composition of the magma. Alternatively, if the magma is erupted it forms volcanic rocks such as basalt, andesite and rhyolite. The water boils quickly to become steam.
Why does magma in a volcano rise up to Earth's surface?
Magma rises because it is less dense than the rock around it.
Why magma rise soon after it forms?
Magma rises soon after it forms because it is less dense than the surrounding solid rock. The less dense magma is buoyant and is able to move upwards through cracks and fractures in the Earth's crust. This process of magma rising is driven by the pressure differences between the magma chamber and the surrounding rocks.
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.
