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
For the Beauty of the Earth of new lyrics not found in the original. The track also has a slightly shorter run time of 3:15. For the Beauty of the Earth "For the Beauty of the Earth" is a Christian hymn by Folliott S. Pierpoint (1835-1917). Pierpoint was 29 at the time he wrote this hymn; he was mesmerized by the beauty of the countryside that surrounded him. It first appeared in 1864 in a book of Eucharistic Hymns and Poems entitled "Lyra Eucharistica, Hymns and Verses on The Holy Communion, Ancient and Modern, with other Poems."
