Hello, and welcome to our new unit on rocks and minerals! To start our unit off, we went on this amazing website and tried to understand the in depth thoughts put into the website. I decided I wanted to first learn about our mysterious unreachable frontier, which is the inside of our Earth. Scientists still aren't sure how many layers of what do we have in our Earth. Well, this is what I learned (for now)...Enjoy!
- The Unreachable Frontier
- Meteorites
- Meteorites can be big rocks that have broken off one of the asteroids in the asteroid belt
- Other meteorites, called chondrites, are meteorites composed from the Solar System's original dust
- These rocks provide clues to our mysterious Earth's core, because space was formed with mostly the same materials
- Two meteorites have come to Earth from the same core and mantle of an asteroid
- Rocks
- Geologists learn about the inner Earth from special rocks called peridotites that come from the upper mantle
- Peridotites also record geological processes that take place inside our Earth
- Rocks can come up from magma that is going to the surface and picks up rocks and diamonds along the way
- Diamonds
- Diamonds are - to geologists - reminders of tremendous temperatures and pressure that is happening in our amazing planet
- Diamonds are the hardest material known to man
- Rapid rising magma carries diamonds from inside the Earth to the surface, like rocks
- Diamonds grow at a depth of 150 km under our feet
As you can see, I learned a lot about what forms and grows inside our Earth, and also about how meteorites show us a bit about our inner Earth. You learned that diamonds are the hardest material known to man, rocks come from inside the Earth, and meteorites come from asteroids which are formed similarly to our Earth. I hope this post teaches you a lot about what scientists think is happening inside our Earth and how many special, interesting and amazing things come out of our amazing planet!
Will add more when more is learned...
