I recently learned that ice is considered to be a rock by Geologists.

Yes, according to geological classifications, ice is considered a rock, particularly when referring to large bodies of ice like glaciers, as it is a naturally occurring solid with a defined crystal structure, meeting the criteria for a mineral and therefore a rock; essentially, glacier ice is considered a metamorphic rock due to the pressure changes it undergoes during formation.

Damn....."On the rocks" makes sense technically then.

Yup. But opals, a gemstone, aren't. They are classified as a "highly viscous fluid".

Which, of course, is what CO2 FRAUD MORONS think of ice ages...


Oh, no, an iceberg broke off, ITS MELTING!!!!!!!!!!!!


In reality, rocks do not grow new layers each year, ice ages do... and that includes GREENLAND

Apparently we really need a "debate" over the term ICE AGE because y'all are all wrong...

What is an ICE AGE? Most apparently still believe it is a terrifying horror movie event where Earth all at once freezes up. The data has never supported such a scenario. Since 2010, there has been a massive effort to re-write Earth climate history into a series of rapid "glaciations" and ice...

On Pluto, ice is as hard as granite.
Technically, I believe that glass is also a "highly viscous fluid" that merely acts like a solid at room temperature, and very old windows are often seen to develop sags and things in them.

That too is correct.

That's actually frozen Nitrogen, not H2O.

There's water ice on the surface there too.

Possibly, but


from Google AI

Pluto's polar caps are primarily composed of nitrogen ice,

Not "possibly" and AI generated BS isn’t to be taken seriously.

The latest spectra from New Horizons Ralph instrument reveal an abundance of methane ice, but with striking differences from place to place across the frozen surface of Pluto.

Yeah? So? Even your first link acknowledges the large amount of water ice. I don't know what you are trying to say.

If 'he's' useful to consider ice as a rock, then have at 'him' ... many minerals found in nature contain water as part of 'her' chemical make-up ...

If 'she's' not an animal, or a plant ... then 'she' must be a rock ... sorry, still getting used to only using two genders ...

Maybe Charlie Brown really got ice cubes.

Igneous, metamorphic or sedimentary?

This statement is correct; a mineral is not a rock, but rather a single, naturally occurring solid with a specific chemical composition and crystalline structure, while a rock is a collection of one or more minerals mixed together, meaning a rock is made up of minerals, not the other way around.

Key points to remember:

• Mineral: A single, pure substance with a defined chemical composition and crystal structure.
• Rock: A solid aggregate composed of multiple minerals.
  

Example: Quartz is a mineral, while granite is a rock made up of several minerals including quartz, feldspar, and mica.

Even granite can flow, over time. High pressure helps.

I'm not a geologist ... but I think if you put that much pressure on granite, an igneous rock, it changes into gneiss, a metamorphic species ... I haven't tumbled either so I don't know ...
