What else can I help you with?
When magma squeezes between layers of rock forms what?
A sill is formed.
When magma squeezes between horizontal lines it forms?
if it squeezes into a fault, its a dike, if it squeezes between horizontal layers, its a sill
Formed when magma is squeezed into horizontal crack between layers of rock and hardens undergroud?
It forms a 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.
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.
What happens when magma flows in a horizontal direction along rock layers?
The magma forms sills and magma chambers.
What feature forms when magma cuts across layers?
feature a and b
What is the landform that when a mass of hardened magma is uplifted causing the layers of rock to bend upward?
The landform is called a laccolith. It forms when magma is injected between layers of sedimentary rock, causing the overlying layers to arch upward. As the magma cools and solidifies, it creates a dome-shaped uplift in the Earth's crust.
Magma that hardens vertically underneath the surface will form a sill?
Yes, that's correct. Sills are igneous rock formations that form when magma is intruded horizontally between rock layers and then solidifies underground. If the magma solidifies vertically underneath the surface, it will create a sill structure.
How are sills and similar?
Dikes and sills are relatively thin. They both have magma to squeeze or force itself across layers of rock.
Is sill a type of lava flow?
A Sill is formed when a fluid rock (usually magma but it can be mud or salt) is squeezed in between the layers (usually horizontal) of older rocks before it solidifies in place. A Dike or Dyke is the opposite, here the fluid rock penetrates across the layering of the older rocks. Logically to get the material to form a Sill there must be an accompanying feeder Dyke.
What is an igneous intrusion that forms between two layers of sedimentary rock?
An igneous intrusion that forms between two layers of sedimentary rock is known as a "sill." Sills occur when molten magma intrudes horizontally between existing rock layers, solidifying into igneous rock as it cools. This process can create distinctive geological features and may alter the surrounding sedimentary layers through heat and pressure. Sills often exhibit a uniform thickness and can vary in composition, depending on the magma source.
