MALE PROFESSOR: As geologists, we examine layers of sediment on the Earth's surface to approximate the dates of past geologic time periods. Uh, sediment, as you know, is material like sand, gravel ⋯ fossil fragments ⋯ that is transported by natural processes, like wind, water flow, ...
But around the time of the rise of plant life, the content of those sediment layers began to change. The coarse grains became much finer, and we see evidence of mud. This suggests that plants promoted the preservation of mud when they sent their roots into the ground. ...
So the upper levels of the soil eventually get depleted of these materials, while the lower levels get enriched with them. And that creates distinct layers of soil as far down as the rock underlying the soil. And the materials that dissolve easily in water can get lost completely if the ...
butMovement's title track has all the classic acid gurgle and giddiness of Aphex Twin circaSurfing on Sine Waves.Meanwhile, "Fade" evokes the dark, disorienting sound of the Knife'sSilent Shoutwith Herndon juxtaposing her vocal layers around a steely beat, providing a master's class in and ...
1961Mouton Rothschild– Still dark in color, the impossible to forget aromatics were filled with Asian spice, truffle, cigar box, cedar wood, fresh strawberry jam, incense, coffee and mint. Packed with layers of sweet, rich, intense, pure, exotic spices and fruit, with plush, opulent...

Sam, go ahead.MALE STUDENT: Doesn't it happen when the oil shoots up to the surface? MALE PROFESSOR: Yes. That’s right.When oil reaches the surface of the earth, there's less pressure on it,and with less pressure, the oil and gas are able to separate.The other way that crude ...
So what caused the monsoon to migrate?Well, the answer is the dynamics of Earth's motions--the same thing that caused the Ice Age, by the way. [slowly, wanting every word to sink in]The Earth's not always the same distance from the Sun. And it's not always tilting toward the Sun...
Dissatisfaction with conventional explanations for dinosaur extinctions led to a surprising observation that, in turn, has suggested a new hypothesis.Many plants and animals disappear abruptly from the fossil record as one moves from layers of rock documenting the end of the Cretaceous up into rocks ...
