About Quote by Seth Shostak
“If you could drive straight down, into a tunnel bored through the crust of the planet, you'd hit this molten mess in about an hour. It's called the asthenosphere - a sluggish sea, several hundred miles thick, on which floats the Earth's cool epidermis - the so-called tectonic plates.”
About This Quote
The asthenosphere is a viscous, semi‑solid layer beneath Earth's crust, allowing tectonic plates to drift like rafts on a slow‑moving sea.
In simple terms: Molten layer lets plates float.
Key Takeaway
Plate tectonics driven by mantle flow.

![“With a pie, the crust is a real delicacy. It's very hard to get it just right because it's got to be cold and just the right consistency. There's a whole art to it and I haven't learned how to do it [filming in Waitress].There's not a lot of time for cooking, especially when you're shooting nights…” quote by Keri Russell](https://sms4smile.com/quotes/img-quotes/160/keri-russell-8795_art_with-a-pie-the-crust-is-a-real-delicacy_384169.jpg)
