Magma is formed deep within the Earth's mantle due to high temperatures and pressure. When magma rises towards the Earth's crust, it does so through fractures or weaknesses in the crust, driven by buoyancy forces. As it ascends, it can create volcanic activity through eruptions or intrusions into the crust.

Is it true that the earth's crust is stationary?

No, the Earth's crust is not stationary. It is divided into several tectonic plates that are constantly moving due to the convection currents in the Earth's mantle. This movement is responsible for phenomena like earthquakes, volcanic eruptions, and the creation of mountain ranges.


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


When magma cools down it is called?

Solidified magma underground is referred to as intrusive igneous rock.


What pushes up the Earth's crust without folding or faulting and also forms mountains?

The movement of tectonic plates pushing against each other can cause the Earth's crust to bulge and rise, forming mountains. This process, known as crustal uplift, occurs when the forces acting on the crust are strong enough to raise it without significant folding or faulting along the way.


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.

Which formation occurs when magma pushes all the way through the exterior of the Earth's crust?

When magma pushes all the way through the Earth's crust, a volcanic eruption occurs. This can lead to the formation of different landforms such as volcanoes, lava flows, and volcanic mountains.


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.


Is magma released from volcanoes material from the core?

No, it's material from the mantle that is forced up due to partial melting of the subducting crust. As it forces its way up, it collects rock from the crust it is passing through and so the result is a mix of the crust and the mantle.


Which of these are examples of magma that has reached the earth's surface?

Examples of magma that has reached the Earth's surface are lava flows, volcanic ash clouds, and pyroclastic flows. These are all products of volcanic eruptions where magma has made its way to the surface through cracks or vents in the Earth's crust.


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.
