When ice cools down it expands

As the glass gets cooler, the ice turns to water and overflows the glass, proving it expands

The glass is clearly colder once the ice is all gone. I don’t know how you argue against that.

Muh.... Global fricking warming. Warming and cooling has been happening forever... Literally forever

Interesting tidbit about mammoth cave, cave divers are reluctant to report any additional unexplored connections to other caved as those caves would be now considered part of a national park with a slew of new regulations and jurisdiction.
That is actually very interesting.
So if the cave was expanded through additional discovery, could the government acquire the land above it by power of eminent domain?

I mean, it's limestone, duh.
It's almost like people have no concept of geology or science.

The shite that kills me is California has some of the toughest pollution laws in the world when it comes to air quality and all the hoops people have to jump through to comply. Yet I guarantee you, that there annual damn wildfires release more CO2 into the atmosphere than every coal plant in the US.
Manage your damn forests.

It's the only thing that makes sense. Sometimes the earth gets tilted and water gets in Kentucky.

To be fair, the wildfire "problem" exists across the entire west. The entire western US was originally composed of fire adapted ecosystems. So, in reality, wildfires are not a problem until human structures get in the way. It's just in California people have built so densely and so close to these systems that the human impact becomes a news story.
Here's this years wildfire map. The entire western US is red.

But how often do you hear about wildfires in Arizona, Idaho, Montana or Wyoming?

Mammoth Cave is so large it actually affects the surrounding airflow, which can be felt at the entrances.
quote:
If you are here on a warm day, you probably feel cool air blowing out of the cave. The rate of this airflow influences cave temperatures.
Summer Airflow
1) Hot surface air expands, becoming less dense, which allows relatively cooler, denser cave air to pour out through lower cave entrances.
2) A partial vacuum is created in the cave. Deep cave temperatures remain between 55 and 57 degrees Fahrenheit year-round.
3) Fresh air is drawn down through higher entrances to replace the exiting air.
Winter Airflow
1) Warm cave air rises upward through denser surface air. These upwellings may be visible as plumes of steam.
2) A partial vacuum is created in the cave
3) Cold air is drawn into lower entrances to replace the exiting air in the same way that a chimney works.

That's basically what they did in the 40s and 50s after it was established (in 1941). It was privately owned before that and a highly competitive business for locals. They displaced something like 400-500 families at that time. I had family who owned property that was displaced themselves and received pennies on the dollar for what the property was actually worth.

I need to check out Mammoth Cave soon. I went when I was young and remember being pretty freaked out.

I have apparently failed in my attempt to create a geological version of a viral math problem.

There's sharks' teeth embedded in the ceiling of Cathedral Caverns in NE Alabama. Was actually there last weekend.

Water is its most dense at 4 degrees Celsius (assuming normal atmospheric pressure).

As a child I was absolutely freaked out by caves, and my damn folks seemed to keep finding their way to them. It was the same every time. We'd go to the touristy part of a cave, and all I'd see is a big ol' dark hole in the ground, and I'd flip my shite. I'd cry and pitch a fit, almost having a legit panic attack. One of them or someone else with us would always end up staying with my while the rest of the family went on their way to certain doom.
I haven't been to many caves since I've been grown, but I still get uneasy in/near them. I suck it up and go, but I'm certainly not the happiest spelunker.
