Lithosphere for silicate rocks, and formula_4 is the age of the given part of the lithosphere. The age is often equal to L/V, where L is the distance from the spreading centre of mid-oceanic ridge, and V is velocity of the lithospheric plate. Oceanic lithosphere is less dense than asthenosphere for a few tens of millions of years but after this becomes increasingly denser than asthenosphere. This is because the chemically differentiated oceanic crust is lighter than asthenosphere, but thermal contraction of the mantle lithosphere makes it more dense than the asthenosphere. The gravitational instability of mature oceanic lithosphere has the
What Is Life clouds above the Krishna scene – so Wilkes abandoned the concept and instead used a darkened photo of Harrison inside the house as the album poster. The more common picture sleeve internationally was a close-up of Feinstein's "All Things Must Pass" front-cover image, taken on the main lawn of Friar Park. In Denmark, the sleeve featured four shots of Harrison, again with guitar, taken on stage during the Delaney & Bonnie tour. At the end of March, "What Is Life" peaked at number 10 on the "Billboard" Hot 100 and number 7 on "Cash Box"s Top 100 chart, making Harrison
