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 is magma in a sill which pushes up to form a rock dome called?
The magma in a sill that pushes up to form a dome-shaped rock structure is called laccolith. Laccoliths form when magma intrudes between layers of sedimentary rock and causes the overlying rocks to arch upwards, resulting in a dome-like structure.
When magma cools down it is called?
Solidified magma underground is referred to as intrusive igneous rock.
What is a layer of cooled magma?
A layer of cooled magma is called a pluton. Plutons form when magma intrudes into the Earth's crust and cools slowly underground, forming large bodies of igneous rock such as granite. They are commonly found in mountainous regions.
This forms when magma flows in a horizontal direction along rock layers?
A dike is formed when magma intrudes and solidifies in a vertical or near-vertical orientation within pre-existing rock layers. Lava flows, on the other hand, occur when magma erupts onto the surface and flows horizontally along the ground.
How does magma affect the rocks into which in intrudes?
Magma is molten rock that bubbles up along ocean ridges to form new crust. Another way that magma forms new crust is when it is expelled out of a volcano and becomes lava, which cools and hardens into crust.
What would cause a metamorphic rock to surround magma?
The contact metamorphism process occurs when magma intrudes into surrounding rock, causing the adjacent rock to be heated and recrystallize into a metamorphic rock. The heat and pressure from the magma alter the mineral composition and texture of the surrounding rock, resulting in the creation of a metamorphic rock zone around the magma.

What is the definition of dike in science?
In science, a dike is a sheet of rock that cuts across the structure of adjacent rock layers. Dikes are formed when magma intrudes into existing rock layers and solidifies. They are often made of igneous rock and can vary in thickness and length.
Describe the factors that might cause magma to form a laccolith instead of a sill?
A laccolith forms when magma is injected into a horizontal crack in the rock layers, causing the overlying rock to arch upwards. This is influenced by factors such as the viscosity of the magma, the amount of pressure exerted, and the density contrast between the magma and surrounding rock. If the magma is less fluid and exerts greater pressure, it is more likely to form a laccolith instead of a sill, which forms when magma intrudes parallel to the rock layers.
What principal involves an intrusive rock body younger then the rock into which it intrudes?
The principal of cross-cutting relationships involves intrusive rock body younger then the rock into which it intrudes.
How can substances in granite enter magma?
Substances in granite can enter magma through a process called assimilation. When magma intrudes into pre-existing rock like granite, it can incorporate elements and minerals from the surrounding rock into the melt, altering its composition. This can happen through melting and assimilation of parts of the granite or through the mixing of magma with granite-derived fluids.
When magma hardens inside the earths crust it can form vertical what and horizontal sills?
When magma hardens inside the Earth's crust, it can form vertical columns known as dikes, and horizontal layers called sills. Dikes form when magma cuts through pre-existing rock layers, while sills are formed when magma intrudes between existing rock layers.
