Why are some igneous rocks coarse and others are smooth

1 answer:

6 0

The reason why some igneous rocks are smooth and some are coarse is the manner in which they formed. We can simply divide the igneous rocks into intrusive and extrusive ones.

The intrusive igneous rocks are formed deep into the ground. The magma that has formed this rocks has been exposed to higher temperatures and pressures. That has led to a very slow cooling off of the magma. Because the magma has been cooling off slowly, the crystals had time and the right conditions to grow larger, thus making the intrusive igneous rocks coarse.

The extrusive igneous rocks are formed on the surface. They have been formed by the lava that once it come out on the surface has been exposed to much lower temperatures and pressures. That has led to very quick cooling off of the lava. Because the lava has cooled off quickly, the crystals didn't had time to grow in size, thus they have remained very small, almost unnoticeable, thus making the extrusive igneous rocks smoother.

A scientist hypothesizes that the water in all of the earths oceans are connected. What would most likely allow this hypothesis

Tresset [83]

The difference between a hypothesis and theory is that the hypothesis is based on observations, but doesn't have a solid proof, while the theory is based on solid proof.

So in order for the scientist to make his hypothesis into theory about the connection of all the Earth's oceans, will need to provide a proof. This proof can be obtained by a sea traveling that will be well documented, and during the travel the scientist to manage to sail through all of the Earth's oceans without having any physical obstacle between any of them.
