WebIgneous rocks which solidify deep underground are called intrusive or Plutonic. They can be observed when erosion wears away overlying layers. When magma reaches the surface it forms volcanic igneous rocks. The texture of these extrusive igneous rocks will vary greatly from ones formed by the same magma deep below the surface. WebOne is a sill, a plate-like layer formed when magma forces its way between two preexisting rock layers. In the example shown, the sill has lifted the overlying rock layers to make room. A second kind of pluton is the dike, a wall-like body formed when a vertical rock fracture is forced open by magma (Figure 11.7). Web12 Apr 2024 · The answer is: an intrusion. More mern peacemaker
