When experts talk about bonding, they're referring to the intense attachment you develop with your baby. It's the feeling that makes you want to shower him with love and affection, or throw yourself in front of a speeding truck to protect him.
Vents and Volcanoes. Most of the active volcanoes on Earth are located underwater, along the aptly named Ring of Fire in the Pacific Ocean. Volcanoes and hydrothermal vents are the result of plate tectonics.
Spreading center volcanism occurs at the site of mid-oceanic ridges, where two plates diverge from one another. As the plates are pulled apart, hot asthenosphere rises upward to fill voids of the extended lithosphere. The rise of this hot mantle provides thermal buoyancy to the ridge area and this is the reason that they stand as high ridges in the center of ocean basins. This is demonstrated in the colored relief images shown here. Mid-oceanic ridge of the south Pacific. As the hot asthenosphere rises to shallow levels, it decompresses and melts to produce basalt magmas. These magmas pond in crustal magma chambers where they are periodically tapped by vertical fractures that provide conduits for the rapid rise of magma to the surface.
