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
Which forms inside the crater of a large volcano?
When magma slowly rises up the inside the crater of a larger volcano, it forms a Lava Dome.
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.
What process makes new crust when the sea floor moves apart and magma rises up?
That is diverging oceanic plates that make a sea-floor ridge and the magma rises up.

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
How are plateus formed?
Plateaus are formed through processes such as constant uplift of landmasses or volcanic activity. Over time, the land is eroded by forces like wind and water, resulting in a flat surface at a high elevation. The geologic forces shaping the earth's crust contribute to the gradual formation of plateaus.

What happens to magma that rises though cracks on the seafloor?
It makes a volcano because as it rises it pushes up the sea floor and it rises.
How is a magma chamber formed in a volcano?
Magma rises through fractures from beneath the crust because it is less dense than the surrounding rock. When the magma cannot find a path upwards it pools into a magma chamber. As more magma rises up below it, the pressure in the chamber grows.
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.
