Volcanism in a Nutshell Volcanism is the eruption of material from deep in the Earth. In many cases, eruptions build up a pile of material, a mountain that is called a volcano. But here I'll discuss volcanism, because most eruptions don't build volcanoes. This is a highly simplified treatment of an intricate subject. Four Types of Magmatic Volcanism The majority of Earth's volcanism happens underwater at the mid-ocean ridges, or, in plate-tectonic language, at divergent margins. This kind of volcanism is mostly a quiet oozing of basalt lava out of long cracks in the seafloor. The second type of volcanism happens in association with subduction zones (that is, convergent margins), places where oceanic plates laden with water and sediment plunge into the hot mantle. Subduction-created magma rises into the lower crust, where it collects and occasionally erupts vigorously, even explosively (see the eight-point Volcanic Explosivity Index or VEI). Products of Volcanism The fluids act underground. Nonmagmatic Volcanism

Collected Quotes from Albert Einstein - StumbleUpon [Note: This list of Einstein quotes was being forwarded around the Internet in e-mail, so I decided to put it on my web page. I'm afraid I can't vouch for its authenticity, tell you where it came from, who compiled the list, who Kevin Harris is, or anything like that. Still, the quotes are interesting and enlightening.] "Any intelligent fool can make things bigger, more complex, and more violent.

Μερικές φορές μπορεί να παρουσιαστεί μία μικρή ποσότητα αίματος κατά την διάρκεια της ωορρηξίας, δηλαδή το χρονικό διάστημα της υψηλής γονιμότητας.

Reproduction MainPlaceHolderTop MainPlaceHolder Human reproduction is when an egg cell from a woman and a sperm cell from a man unite and develop in the womb to form a baby. A number of organs and structures in both the woman and the man are needed in order for this process to occur. These are called the reproductive organs and genitals. The male reproductive system In males, the reproductive organs and genitals include: testes, also called testicles: a pair of oval-shaped glands that produce sperm scrotum: the pouch of skin that contains the testes penis: the male reproductive organ, through which urine and semen pass prostate gland: a gland that produces some of the fluid part of semen seminal vesicles: a pair of glands that also produce some of the fluid part of semen vas deferens: a pair of ducts leading from the testes to the seminal vesicle, through which the sperm travel The female reproductive system In females, the reproductive organs and genitals include: Ovulation and fertilization Reviewed By
Seven Speaking Tips That Beat "Pretend Your Audience Is Naked& | Psychology Today - StumbleUpon Aggh. Everyone showed up clothed! Once upon a time, I suffered from glossophobia. This affliction touches billions. I conquered it by discovering what makes people smile, nod, and listen carefully, because nothing calms you down faster than an interested audience. This is what I've learned. Children plea for them at night, and adults crave them, too. They want to be respected. This principle also underlies another rule of effective speaking: Dress like your audience, but just a little bit better." {*style:<i>Don't try to impress them. </i>*} If you truly want to help your listeners--by informing or motivating them, or improving their lives--they will care and listen. This recalls a favorite tip: We mistrust people who won't look us in the eyes--even if our eyes are among over 200 sets in a room. If you look each person in the eye for a few seconds, you make each person feel important--a feeling that every person craves. For this reason, minimize visual aids. . .
