Do normal faults result in crustal shortening?
No, normal faults result in crustal extension, not shortening. Normal faults form as a result of tensional stresses that stretch the Earth's crust, causing one block of rock to move downward relative to the other block. Crustal shortening is typically associated with reverse faults or thrust faults, where compressional stresses push rocks together, shortening the crust.
Which formation occurs when large quantities of magma begin to push through mantle of the Earth and into layers of the crust?
When large quantities of magma push through the Earth's mantle and into the crust, it can create a volcanic formation known as a volcanic hotspot or a volcanic arc. This process often leads to the formation of volcanoes, volcanic mountains, and lava flows on the Earth's surface.
How does the Earth's crust respond to heat from below?
When heat rises from below, it can cause the Earth's crust to melt and form magma. This magma may eventually push through to the surface in the form of volcanic eruptions or intrude into the crust, leading to the formation of igneous rocks. Additionally, the heat can alter the physical and chemical properties of the surrounding rock, leading to metamorphism.
These mountains form from pools of magma that accumulate underground and push up on crustal plates.?
dome
How does magma rise?
Magma is more buoyant than lithospheric rock, and as such it will push toward the surface. On the continents, magma in intrusions can follow weaknesses in the crustal rock to reach the surface, or in some cases, simply melt its way through from the heat delivered by the intrusion. At divergent plate boundaries, where the lithospheric plates are pulling apart, hot rock from the mantle rises and melts from decompression melting, filling the space left from the parting plates. At so-called hotspots, such as the Hawaiian volcanic mountain chain, magma plumes are thought to rise up from the mantle-core boundary and burn through the moving lithospheric plates, creating first submarine volcanoes, then islands.
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.
Why does magma move through the volcanoes?
Because nothing can be still and if more magma forms it has to push the rest away
What is the effect of magma pushing up through cracks in the ocean floor?
push and a pull
Why does magma sometimes push through earth's surface and make a volcano?
because of pressure
When magma from beneath the earth project surface is push up but doesn't actually crack through?
Sometimes it matters how strong the magma is because it has to have alot of force to break through
How motion along faults causes earthquakes?
The plates push against eachother and eventually slip which cause the ground to shake.
Why does magma push toward Earth's surface?
Because the tectonic plates push it up and it flow through cracks.It's temperature is more than 3000 degrees!
Is magma push up through cracks in the earth's crust?
No its in the earth center or core if you will. Lava is outer magma is inner and the difference is the heat magma hotter lava's cooler but both are over 1000 degrees.
Which occurs when large quantities of magma begin to push through mantle of the earth and into layers of the crust?
dome mountain
Which formation occurs when large quantities of magma begin to push through mantle of the earth and into layers of crust?
dome mountain
Earthquakes result when forces push what along faults in earths lithosphere?
Earthquakes result when forces push plates along faults in the Earth's lithosphere. These plates are comprised of the crust and a portion of the upper mantle.
Do normal faults result in crustal shortening?

Normal faults form as a result of tensional stresses that stretch the Earth's crust, causing one block of rock to move downward relative to the other block.
