Is it true that the earth's crust is stationary?
The crust is formed on tectonic plates that are always moving because of the magma melting the rock under the surface causing them to move, so, in a way the Earth's crust is moving.
What is vocanicity?
volcanicity is the process where by magma in the interior of the earth crust forced it way out to the earth surface cause by intense pressure in the interior of the crust there by forcing the earth crust to expand and causing a crack which will intend force it self through flowing out to form hard igneous rocks
Describe two igneous structures that form under earths surface?
Igneous rocks are formed from the molten liquid minerals that lie below the earth's crust. Intrusive igneous rocks forms in magma chambers that are deep underground it is molten by heat and pressure. Extrusive igneous rocks forms when magma makes its way to Earth's surface when the molten rock erupts.Jennifer
How does interior heat reach earths surface?
Imagine the mantle (the hot bit under the Earth's crust), like a lava lamp. The hot magma, which has been heated right down at the very bottom, near the outer core, is less dense then the rest of the magma. It rises, like your lava lamp bubble, until it reaches the crust. If it's hot enough, the magma can melt it's way through to the surface, causing those things we call volcanoes to form.
When magma cools down it is called?
Solidified magma underground is referred to as intrusive igneous rock.
What is the molten material under the earth's crust?
Magma

Which formation occurs when magma pushes all the way through the exterior the earth's crust?
volcanic mountain
Which formation occurs when magma pushes all of the way through the exterior of the Earth's crust?
volcanic mountain
What is rising magma that maybe force its way through earth's crust not at a plate boundary?
hot spot
Which formation occurs when magma pushes all the way through the exterior of the Earth's crust?
volcanic mountain
Is magma released from volcanoes material from the core?
No, magma is not material from the core of the Earth. Magma is molten rock that is generated in the Earth's mantle, which lies between the core and the crust. Magma can rise to the surface during volcanic eruptions, forming lava flows or erupting explosively.

What happens as magma in a magma chamber forces its way up through weak spots of the crust?
The surface of the crust will bulge, and an eruption of a volcano may occur.

What would happen first in order for a new island to be created by volcanic eruption?
Magma must find its way toward the surface of the crust.
How is crust different than mantle?
The crust is the ground that people have built the building and have grown the trees on. The mantle on the other hand is way down into the earth. It has the magma and gasses and other material in it. The difference is that we can not stand on the mantle or we will burn. the crust is the outer layer of the earth, while the mantle is inside near the core.
