What else can I help you with?
Which type of intrusive feature forms when when magma is injected into fractures cutting across rock layers?
sill
What is the slab that forms when magma forces itself across rock layers?
The slab that forms when magma forces itself across rock layers is called a dike.
Which type of instructive feature forms when magma is injected into fractures the cut across rock layers?
The instructive feature that forms when magma is injected into fractures that cut across rock layers is called a "dike." Dikes are typically vertical or steeply inclined and can vary in thickness, often cooling quickly as they intrude into the surrounding rock. They are formed when magma forces its way into existing cracks, solidifying as it cools and creating a distinct geological feature.
Which type of intrusive feature forms when magma is injected into fractures cutting across preexisting rock layers?
Dikes are intrusive features that form when magma is injected into fractures that cut across preexisting rock layers. Dikes are tabular structures that can range in width from a few centimeters to tens of meters and can extend for kilometers.
Which type of intrusive feature when magma is injected into fractures cutting across preexisting rock layers?
sill
What forms when magma forces itself across rock layers?
When magma forces itself across rock layers, it can create igneous intrusions such as dikes (vertical sheet-like intrusions) or sills (horizontal sheet-like intrusions). These intrusions form when magma solidifies as it cools, creating distinctive structures within the surrounding rock layers.
Slab that forms when magma forces itself across rock layers?
The slab of volcanic rock that is formed when magma forces itself across rock layers is called a dike. This will eventually build into mountains.
What is a dike in volcano?
A dike in a volcano is a vertical or near-vertical fracture that cuts across the rock layers, through which magma can flow to the surface during an eruption. Dikes are essential conduits for magma transport in volcanic systems and can create pathways for lava to reach the surface. They are often associated with volcanic activity and can be observed in volcanic regions around the world.
Does a dike form when magma forces itself between rock layers and hardens?
Yes, a dike forms when magma intrudes into existing rock layers and solidifies. As the magma cools and solidifies underground, it creates a vertical or near-vertical sheet-like body of igneous rock that cuts across the existing rock layers.
An igneous intrusive feature that forms from the lens shape mass of magma the 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 are typically dome-shaped and can create significant topographical features due to their ability to push the surrounding rock layers upward. They are formed when magma intrudes between layers of sedimentary rock but does not reach the surface.
What happens when magma flows in a horizontal direction along rock layers?
The magma forms sills and magma chambers.
What forms when magma flows horizontally along rock layers?
When magma flows horizontally along rock layers, it can form a feature called a sill. Sills are tabular igneous intrusions that are parallel to the surrounding rock layers. They are typically formed when magma is injected between existing rock layers and cools and solidifies underground.
