Single Mineral!!!!! I chose Tantulum as my single mineral. I found it in the Liberal Studies office periodic table display on April 30, 2025. It's commonly found in Austria, Nigeria, and Brazil, as well as other places that have lots of granite and igneous rocks. It's mined from open-pit and underground mines. It's usually extracted from ore minerals like columbite-tantalite, aand is always found in conjuction with niobium. The process of that includes leaching seperation and reduction. It can also be a byproduct from tin mining operations. Though it's pretty rare, it's used in electronic curcits and capacitors which then goes into making TVs, phones, battery chargers, etc. It's useful because it's very durable and hard and has a high melting point which means it has a lot of resistence to heat. Though it's mostly used for electronics, it's used in a lot of other things, too, like jewelry, spacecrafts, superalloys used in tanks and missles. Howeve...

Erosion at the Sand Dunes!!!! All of the sand at the dunes are considered sediment and there's erostion because these sediments are being moved. This is a GIANT place (as you can see from the photo of me standing on the dune) in Pismo, CA. I think that there may have been even bigger erosion in the past but there still is erosion that takes place now from the gravity and the wind. These photos are from last weekend. I've also been there on super windy days where you can see sand flying all around and it moves like crazy. I think on normal days the sediment doesn't move very far and stays within the dunes just moving around from hill to hill and creating different dunes maybe. Movement of sediment can travel even further thoguh with people who visit the dunes getting sand in their clothes and shoes and leaving with it. I think that this erosion has been happening for as long as the dunes have existed because they're tall hills and so there will always be sand that ...

Rock #1 My rock to scale with my hand. Location: My Backyard!!! Date: 6:20 p.m. on Sunday, April 6, 2025 This is my rock. I found it in my backyard today. The area has lots of small rocks, but the one I chose is different because it's bigger and there was a little blue mark on it that might be form paint or chalk. I think that it might've been formed somewhere else because all of the rest of the surrounding rocks were uniform, and this one wasn't.  A selfie of me with my rock!
