Lithosphere-Asthenosphere boundary a thermal control of oceanic-lithosphere thickness. The continental lithosphere contains an ancient, stable part known as the craton. The LAB is particularly difficult to study in these regions and evidence suggests that the lithosphere within this old part of the continent is at it thickest and even appears to exhibit large variations in thickness beneath the cratons, thus supporting the theory that lithosphere thickness and LAB depth are age-dependent. Depths of the LAB beneath these regions (also known as shields and platforms) are estimated to be between 200 and 250 km deep. Beneath Phanerozoic continental crust, the LAB is roughly
This Is What the Truth Feels Like few weeks before its release. The seventh track, "Send Me a Picture", has dancehall elements, and was described as a sexting ode by several publications; furthermore, Mapes stated the song has a "Bieber-hits-the-islands vibe", while Annie Zaleski of "The A.V. Club" summarized its meaning as "captur[ing] the delicious anticipation of a crush potentially texting a snap". "Red Flag" begins with "an intro that sounds like a melting violin", followed by Stefani scorning her ex: "This is what happens when you don't listen to what your mother say." Amanda Dykan of AltWire found it reminiscent of 2000's "Ex-Girlfriend" and compared Stefani's
