Andy is a 12 year old quartz grain. Every year the quartz tribe hosts the "Uplifting Event". This year Andy wants to be a part of this so he begs his parents to let him sign up. The "Uplifting Event" is a volcanic eruption that occurs every year and brings quartz grains, along with other grains, to Earth's surface and there, the grains learn more about the world they live in.
The "Uplifting Event" is a volcanic eruption that occurs once a year. This eruption brings the grains to Earth's surface.
Uplifting Event Sign-Ups
Andy's parents allow him to sign up for the Uplifting Event. They warn him about the dangers, but like any other excited child, he ignores them.
Andy is now on Earth's surface mixed with other grains and sediments. The formation of SEDIMENTARY rocks begin. During this, the minerals grow and sediments are blown on top of the minerals and other sediments.
Andy and the other quartz grains were "cemented" together to form this SEDIMENTARY rock. When these rocks cool, minerals and sediments get stuck together to form this rock. Andy is stuck with many other minerals and grains.
The SEDIMENTARY rock was affected by erosion and weather so it broke up a little and because of the weight of the other sediments and everything that was buried on top of it, it started to be pushed under the Earth's surface. The minerals in this rock would melt when the rock is pushed deeper and deeper in Earth's surface, cool and recrytallize.
The melted minerals,which is also called magma, combines with other melted minerals. When the magma cools, it forms a new rock with different characteristics than the original rock. This is a Metamorphic rock, which is mainly caused by increasing temperature and pressure.
Andy and his friends were the last minerals to melt
This is what Andy and his friends look like now!
Finally the magma cooled and now andy and his friends recrystallized and formed an IGNEOUS rock!
Thanks for watching guys! There were probably some words in there you didn't know. But dont worry, lets go back and recap!
The first one was Sedimentary rocks. These rocks are formed of sediments, which are pieces of solid material that have been deposited on earth's surface by wind, water, ice or gravity. These sediments are cemented together and we have our sedimentary rock.
The next word is Metamorphic. Metamorphic rocks are rocks that go through big changes in both their composition (what they're made up of) and their appearance. The two major things that cause Metamorphic rocks are an increase in temperature AND pressure.
The last one is Igneous. Igneous rocks are rocks that form from the crystalization of magma. There are two types of Igneous rocks.
1. Extrusive: igneous rocks that form on Earth's surface. 2. Intrusive: igneous rocks that form beneath earth's surface. An example of this is granite, if any of you have granite counter-tops at home, you know what it is. When magma cooled, Andy and his quartz friends turned into granite.
