<h3>Ovary: The female gonad, one of a pair of reproductive glands in women. The ovaries are located in the pelvis, one on each side of the uterus. Each ovary is about the size and shape of an almond. The ovaries produce eggs (ova) and female hormones. During each monthly menstrual cycle, an egg is released from one ovary.</h3>
Scientist have learned by studying seismic waves that the earth has liquid in its outer core. They also can predict if a earthquake might happen in a spot in the next hundred years or so.
