Conduction and Natural Processes (formation of rocks and minerals)
What is conduction, anyways?
Conduction is the direct contact with one atom to another through electricity or heat. Conduction occurs through a solid, liquid or a gas.
Rocks are formed through either thermal or electric conduction, convection, and radiation. The three main rocks groups are:
- Igneous rocks: rocks made from hot magma (and it's a good example of conduction.)
- Sedimentary rocks: sand or mud is compressed and eventually become rocks.
- Metamorphic rocks: rocks made up of Sedimentary and Igneous rocks.
HOW IGNEOUS ROCKS ARE FORMED FROM CONDUCTION
Igneous rocks are formed when magma is cooled either underneath or over the ground of the earth. Now this is the part where conduction comes in. The magma underneath the ground rises through volcanic eruption, and most of the magma erupts out. When the magma flows down the volcano, conduction comes into place. The magma transfers heat from the warmer part of the magma to the slightly cooler, and when the particles come together and cool off they turn into igneous rocks. These igneous rocks are called extrusive igneous rocks.
