Crustal Quotes & Sayings

You have all the fears of mortals and all the desires of immortals. — Seneca.

But you need to make sure that the last thing you remember about today isn't that you fell down, it's that you got back up again. That's what we do when bad things happen to us. — Michael Rowe

Gaia is a thin spherical shell of matter that surrounds the incandescent interior; it begins where the crustal rocks meet the magma of the Earth's hot interior, about 100 miles below the surface, and proceeds another 100 miles outwards through the ocean and air to the even hotter thermosphere at the edge of space. It includes the biosphere and is a dynamic physiological system that has kept our planet fit for life for over three billion years. I call Gaia a physiological system because it appears to have the unconscious goal of regulating the climate and the chemistry at a comfortable state for life. Its goals are not set points but adjustable for whatever is the current environment and adaptable to whatever forms of life it carries. — James E. Lovelock

Nothing is more admirable, than the readiness, with which the imagination suggests its ideas, and presents them at the very instant, in which they become necessary or useful. — David Hume

Three dominant hypotheses explain what drives plate tectonic motion. Each one relies on the convention of the mantle - the movement of heated rock materials beneath earth's crust - but each one focuses on a different piece of the cycle: Mantle convection hypothesis: This hypothesis proposes that heated materials inside the earth move up and down in a circular motion (like the wax in a lava lamp) and the continental plates resting on this mat-erial are moved in the direction of the circular motion. Ridge-push hypothesis: This hypothesis states that the creation of new rock materials along mid-ocean ridges continually pushes oceanic crustal plates upward and outward, so that the far edges are forced into collisions with other plates. Slab-pull hypothesis: This hypothesis is the opposite of the ridge-push model. It proposes that the heavy, dense outer edges of crustal plates sink into the mantle at plate boundaries and pull the rest of the plate along with them. — Alecia M. Spooner

Studies of immigration show that this resistance to heart disease is not just something in African or Chinese genes. When people move from low-risk to high-risk areas, disease rates skyrocket as they adopt Western diets and lifestyles. — Michael Greger
