Hi I saw your reply on a post about weird things people believe in (in terms of science) and you wrote about that unless one stands on a volcano, its solid rock down to the outer core and I had to google it because I was always taught that THE MANTLE IS LIQUID not by movies but by SCHOOL and now I learn it's a case of 'technically-' and I'm shaking so, uh, thanks.

Hello! Sorry I sat on this, I wanted to respond with this earth structure diagram I've been working on. I think most public schools in the US do a terrible job of teaching geology and it actually drives me insane lol. Also, if learning the mantle is not liquid blew your mind, then this is gonna blow your mind too...

The mantle is green!

This is a pretty quick and dirty diagram, but I wanted to show the earth in a way that we don't usually think about (usually it just looks "hotter" as you go toward the center). Here are some earth facts I wish everyone knew:

The Crust - relatively super thin, very brittle, mostly granite, and things get weird where the crust transitions to mantle and where plates collide (might make a second post on that).

The Mantle - primarily made up of a rock called peridotite, which has lots of olivine in it and is blasphemously green. Also the mantle is pretty much all rock, maybe a little magma here and there, but it's pretty minor. But because all that rock is really, really hot it can deform plastically and it actually undergoes convection (it moves!) Mantle upwelling (shown in that lighter green) is actually a huge driver of plate tectonics.

The Core - made of an iron and nickel alloy, the outer core is liquid (because it's so hot) and the inner core is solid (because the pressure is so high). This dual metallic core generates Earth's magnet field (our planet is one big magnet). We also suspect that inner core has Widmanstätten patterns, similar to those we find in meteorites.

So yeah, hoped you liked some more earth facts 😅

Are you an American? Frustrated by the political process? Do you feel like you have no voice in our government? Let me introduce you to the wonderful world of public comments. 

This is where federal agencies propose new regulations asking for public feedback:

Regulations.gov

Here's a step by step on how to navigate this:

Look through the proposals on the explore tab and filter by "Proposed Rule". These are the regulations that have been proposed, but not finalized. 

If you click on these, they are pretty dense, text heavy explanations of the proposed rule changes. I definitely do a lot of googling when trying to understand what I'm reading. Also there are a lot of different topics here and I definitely don't comment on everything.

This is how you make a public comment. For example, for this proposed rule:

Start a new document and write the subject and docket number. Your comment NEEDS to have the docket number for them to count it most of the time, and the correct subject some of the time.

^^ this is ambiguous, but add the docket ID and subject just to be safe, it should look like this:

Ref: Docket ID No. NSD 104

Provisions Pertaining to Preventing Access to Americans' Bulk Sensitive Personal Data and U.S. Government-Related Data by Countries of Concern

Then address to the person at the very very end of the page. 

Scroll all the way to the end:

^^this is the person you address to. 

Then introduce yourself. If you have experience related to the proposed rule, talk about that. For rules related to the environment and public health I say that I'm a geologist with a master's degree and I work in environmental remediation. Otherwise, I just say I'm a concerned citizen. 

Then I say hey I agree/ disagree with this proposed rule and here's why. Oftentimes there will be lists that the federal agency is asking for specific feedback on.

Commenting on these will have a lot of impact. 

Here's an example comment I forgot to post for a rule regarding methane emissions in the oil and gas industry:

Administrator Michael Regan The United States Environmental Protection Agency 1200 Pennsylvania Avenue, N.W. Washington, DC 20460

Ref: Docket ID No. __ Waste Emissions Charge for Petroleum and Natural Gas Systems Dear Administrator Regan, My name is __ and I am writing to you as a geologist and graduate of ___.  I currently work in ____. Thank you for your interest in reducing methane pollution, which I believe to be one of the most important aspects in reducing the harm caused by the climate crisis. Within the short term, methane is a much more powerful force of global warming than carbon dioxide. It breaks down faster than carbon dioxide— but it traps significantly more heat that should be bouncing back into space. When scientists talk about taking our foot off the gas pedal in regards to the climate crisis, methane is at the forefront of our minds. Natural gas is often proposed as a solution to reducing our greenhouse gas emissions (since it produces less carbon dioxide than coal plants), but these methane leaks are a serious threat to public health. Not only is methane hazardous, it’s ability to cause short-term superheating is contributing to the rapid increase in wildfires within the U.S. and globally, further degrading air quality. Last summer in NYC skies were orange, caused by ash from Canadian wildfires. As someone who sets up air monitoring equipment every day to ensure the surrounding community is not impacted from the disposal of hazardous waste, I have a unique opportunity to see on a day-to-day basis how air quality is degrading. I strongly support the Environmental Protection Agency's proposed waste emissions charge. For EPA’s implementation of the fee to fulfill Congress’s goals, the final regulation must continue to include key requirements including: ·       Regulatory compliance exemptions must only become available after final standards and plans are in effect in all states and that these plans are at least as strong as the EPA's 202 methane emissions proposal. Operators filing for exemption must also demonstrate full compliance across their facilities; ·       Strong and clear criteria must remain in place for operators seeking an exemption based on unreasonable permitting delays; ·       When operators seek an exemption for plugged wells, they must clearly demonstrate that their wells have been properly plugged and are no longer polluting; ·       Transparent calculations and methodologies to accurately determine an owner or operator’s net emissions; and ·       Strong verification protocols so that fee obligations accurately reflect reported emissions and that exemptions are only available once the conditions Congress set forth are met. I urge the EPA to quickly finalize this proposal with limited flaring, strengthened emissions standards for storage tanks, and a pathway for enhanced community monitoring. Thank you, ___________

And then paste your comment in or upload a document and submit! You will be asked to provide your name and address. Also the FCC will only take comments on their website, but the proposed rule will be posted on the federal regulations website I put above and they should have a link to the FCC website within that post.

So I had to do hazardous waste training for my job:

It’s ok to sin guys

I think about this ammonite fossil every day

Happy moon landing!

I love this photo because it really shows just how far we made it from Earth.
