This is our web page where we will teach you about rocks and the rock cycle!!!
There are 3 major types of rocks Igneous, Metamorphic,& Sedimentary.
Shown here in this picture you will learn about how the rock cycle works. It shows where Sedimentary rocks form, Metamorphic rocks form, & Igneous.
These are the different types of rocks & minerals. They are the main types of minerals, Sedimentary rocks, Igneous rocks, & metamorphic rocks. All these rocks have differant textures & colors.
This is a Igneous rock called Haematite. It has lots of bubbles because it's a Igneous rock.
Title:Haematite
Description:Haematite is the most important mineral ore of iron and occurs in two forms. The first is kidney ore which appears as rounded dark red masses with a metallic sheen. The second is specular iron that consists of tabular black crystals. The specimen in the photograph is kidney ore.Credit:Shropshire County Museum ServiceSource:Shropshire County Museum Service

This rock is made up of and contains many minerals in it this makes the color of the rock in many colors.
Geology is just one of the many scientific disciplines that have fascinated me over the years. As a teenager, I became fanatical about collecting rocks, rock minerals, crystals and fossils, every specimen of which I arranged fastidiously along the wall shelf that overlooked my desk (see photo below). I am proud to say that this extensive collection has been lovingly preserved in its original arrangement by my mother, starting with translucent colourless quartzite crystals, ranging right through the colours of the rainbow and ending with opaque, jet black fragments of obsidian. Dust and the occasional long-dead beetle aside, not a single rock has been discarded. They’re all there and they’re all special. I would like to extend a thank you to my mom for preserving my collection, although it wouldn’t hurt you to dust once in a while…
This photo was captured at the very heart of Lower Antelope Canyon near Page, AZ. Our Navajo guide took us down into the canyon and we shot and explored at every turn. I’d been here before, and it was a treat to come back.
As we walked along, our hushed voices echoing off the canyon walls, I only half-heartedly listened to our guide. Most of my attention was directed towards the wonderful curves and sandstone textures that surrounded us. The cool, inviting air in the canyon was intoxicating - especially when compared to the scalding, nearly 100 degree temps on the desert above.
Each corner presented a new photo opportunity. Grant and I would stop at nearly every turn for a photo. Around one such turn was the amazing formation you see in the photo above. I usually go for more “real” names, but to me this formation looks like an all-seeing eye, watching over the canyon. So, the name kind of picked itself in this case.
The incredible colors are a direct result of the reflected light that illuminates the photo. The sun was hitting a canyon wall directly above us, and the reflection off the rock creates the light source for the photo.

Chemical Composition: Silicon, magnesium, iron and oxygen
Why it makes this list: Its formation process is rad
Name Origin: “Obsius” after the Roman who apparently discovered this rock in Ethiopia.
Star Sign: Haha, just kidding!
Obsidian is a jet black stone with a vitreous (glassy) lustre. Just like glass, obsidian tends to shatter into sharp fragments when hit hard, although it is much stronger than the glass in a bottle is made of, so smashing it against your head wouldn’t be advisable. Unless you’re the kind of person who would actually smash a bottle against your head, in which case: knock yourself out. Literally.
Obsidian’s strength and brittleness have resulted in its use as sharp cutting implements and weapons (spear and arrowheads), some of which date back as many as six million years. Ancient Egyptians found obsidian to offer a suitable artistic representation of the iris.
