An igneous intrusive feature that forms from a lens shaped mass of magma that arches the overlying strata upward is called a what?
An igneous intrusive feature that forms from a lens-shaped mass of magma that arches the overlying strata upward is called a laccolith. Laccoliths typically create a dome-like structure as the magma pushes the surrounding rock layers upward. They are often associated with volcanic activity and can vary in size.
If you wanted to locate a domr mountain you would want to locate an area where magma rises through the crust and pushes rock layers above the magma?
To locate a dome mountain, you would look for regions where magma has intruded into the Earth's crust, causing the surrounding rock layers to bulge upward. This process often involves the accumulation of magma beneath the surface, which exerts pressure and deforms the overlying rocks. The result is a dome-shaped elevation that can be characterized by a circular or oval appearance when viewed from above. Areas with historical volcanic activity or tectonic uplift are typically good candidates for finding dome mountains.
Which type if fold is created when the crust bends and curves upward?
When the crust bends and curves upward, it creates an anticline fold. Anticlines are characterized by their arch-like shape, where the oldest rock layers are typically found at the core of the fold. This type of fold is often formed through compressional forces that push the crust together.
What boundary allows magma to rise to the surface to make new crust?
Magma rises to the surface to create new crust primarily at divergent boundaries, where tectonic plates are moving apart. This movement allows magma from the mantle to fill the gap, solidifying as it cools and forming new crust, often seen at mid-ocean ridges. Additionally, magma can also rise at convergent boundaries where subduction occurs, although this typically leads to volcanic activity rather than the creation of new oceanic crust.
Why Volcanoes often form?
When the crust under the earth gets pushed up and then the magma gets really hot and BLOWS UP.
How can you use magma in a sentence?
The scientist was determined to get some magma to use in his research. Magma is the hot fluid that is in the Earth's crust.

What name is often given to the area where volcanoes often occur because convection in the earth's mantle produces a column of magma that rises into the crust?
hotspots

How does the crust renew its gap?
not exactly sure what you mean by this. but if i am, as crust is destroyed and turned to partial melted magma at destructive plates margins, new crust is formed at constructive plate margin which are often at mid-ocean ridges, e.g. the Mid-Atlantic Ridge.
What name is given to the area where volcanoes often occurs because convection in the earths mantle produces a column of magma that rises into the crust?
hotspots
Why might diverging plates cause a volcano to form?
Diverging plates are associated with stretching and thinning of the crust. Lines of weakness or rifts in the thinner crust serve as conduits for magma and volcanoes often form.

hotspots
Why is magma not often made of sedimentary rock?
because magma are molten materials which exist below the solid rock of the earth's crust .we sedimentary rocks are formed by the result of deposition or accumulation and lithification of sediments of some weathered particles and other different materials therefore magma not often made because they don't contain fossils
What is the weak area in the earth's crust where magma rises?
The weak area in the Earth's crust where magma rises is known as a magma chamber or a volcanic conduit. These regions are characterized by lower pressure and temperature, allowing molten rock to accumulate and move toward the surface. When the pressure builds sufficiently, it can lead to volcanic eruptions. Additionally, these areas are often associated with tectonic plate boundaries or hotspots.
What is a thin place on Earths crust called where a volcanoes can form?
A thin place on Earth's crust where a volcano can form is called a "hotspot." This is a location where magma from the mantle rises to the surface, often creating volcanic activity. As the magma erupts through the Earth's crust, it can result in the formation of volcanic features like volcanoes, lava flows, and volcanic islands.
Are there often earthquakes before volcanoes?
Earthquakes are a common precursor to Volcanic eruptions due to shifts in the planets crust caused by the shifting of magma underneath the earth.
