Magma (molten rock) is generally a homogenous mix of mineral components. When it solidifies, it is usually a homogenous texture. Layering is usually evident in sedimentary rocks , each layer representing another contribution to the rock, or in metamorphic rocks, the layers being formed from the consolidation of minerals due to heat and pressure.

What causes igneous rocks to become sedimentary rocks?

If other layers of rock, dirt, dust, and sand are put on top of the igneous rock and the layers are compressed by their own weight, they become a single, unified layer of sedimentary rock. Simple Version: 1. Igneous rock 2. More rocks are put on the igneous rock. 3. The rock on top push down and squeeze the all of the layers into one layer.

How is igneous rock transported?

Igneous rock is transported by wind or moving water until they are deposited in other regions where they settle in layers.


Sheets of igneous rock that are parallel to the layers they intrude?

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.


How can igneous rock disturb sedimentary rock layers?

Igneous rocks can disturb sedimentary rock layers and formations by their movement during ascent through such layer. when they make contact with this sedimentary rocks they could result to folding and/or metamorphism.
