Origin of Igneous Rocks

With minerals better understood, it's time to discuss rocks. The first type of rock we will discuss is igneous rock. These rocks are formed when magma/lava crystallizes. But how does the mantle rock melt to form magma in the first place? What is the composition of igneous rock? There's a lot more to it than you might think, so let's check it out!

Wow. In all my lay reading and watching geology content I've never heard of the role decompression plays in the melting. You're a gem, Dave.

@chrisconklin2981 Год назад

Thanks. l love a good geology lesson and North America is a great place to study it. As I live in Florida, I am partial to sand and often ask people if they know where all of this sand comes from? It turns out that our sand is crystalline quartz and is the final residual result of igneous granite weathering,. For millions of years the wearing down of the Appalachian mountains has sent sand downstream to the Atlantic and Gulf. Coastal currents move that sand south, so now I live on top of an ancient sand dune.

I would love to study Geology in the North America, but I’m struggling with some of the scholarships offered

@elliejohnson2786 Год назад

Great video! Much more detail than my high school class, and more specific with names so I can do further research to understand these concepts, rather than just simply being told that there are different rocks and what their names are.

@VAPhillyFan54 Год назад

Probably have to watch this twice, but undoubtedly this ties in to the early uses of obsidian. Nice video.

I been telling my college chemistry teacher about you. She might start using your content in her lessons :D I also told my Earth Science teacher about this video aswell! Really enjoying your content!

@WetDoggo Год назад

so if you want to harvest olivine, you just need to keep a pool of lava at the right temperature for long enough, then pump off the still molten parts to crystallize out other minerals... then you can get to the olivine layer easier and you just need to break up the rock

@basharatmalik2004 Год назад

Sir if a quantity say x is directly proportional to y, does it imply that y is also proportional to x. I mean that is proportionality between two variables both ways correct. Thanks

I have a lump of mixture of materials from the seaside and I am looking for someone to analyse it. This video was a start to my understanding as to what I have found.

@gordtvradio3465 Год назад

Any easy test that you can do is drop some dilute HCl on it to see if it fizzes. That will tell you whether or not it is calcium carbonate

@HH-ru4bj Год назад

Youve probably already covered it (difficy.to remember with so many videos) but the hydrogen anions as water was one of the things that really frustrated me when creationists would claim that's where the water went after the flood.

@izzyfury8126 Год назад

What frustrates me is when us mere mortals get intellectual stimulus we suddenly think we know more than Creation and the Creator of all elements.

@alexyu5920 Год назад

Different types of rocks have different atomic-cubic structure, which mentioned in inorganic chemistry.

@alexmcd378 Год назад

Whatever the conditions near the mantle, it did not consist of a pristine laboratory. I don't understand why some would suggest you do chemistry in these conditions. Do you have any references on that?! ;D

So dumb. Everyone knows god makes rocks in one day. 😂 sorry I couldn’t help myself… another great video from the Professor! He does a great job of explaining. There’s a newer image of what seismologists believe the molten lava inside the earth looks like, with massive bulges and very, very different than just a sphere or blob
