The body has an amazing ability to heal â but itâs not perfect. Below: April 29 â Every scar tells a story â about the time you fell from your bike or the day you burnt your hand. Every scar also tells about the bodyâs amazing ability to heal itself. But itâs not perfect.
Lava flow during a rift eruption at Krafla, Iceland in 1984. Lava is the molten rock expelled by a volcano during an eruption and the resulting rock after solidification and cooling.This molten rock is formed in the interior of some planets, including Earth, and some of their satellites.The source of the heat that melts the rock within the earth is geothermal energy.When first erupted from a volcanic vent, lava is a liquid at temperatures from 700 to 1,200 Â°C (1,292 to 2,192 Â°F).his molten rock is formed in the interior of some planets, including Earth, and some of their satellites.

A pyroclastic flow is essentially an avalanche of ash, rock, and gas that flows down the slopes of a volcano at great speed. Temperatures inside these flows can be well over 1 â¦ ,000 degrees Fahrenheit, which is unsurvivable for any human, plant, or animal. pyroclastic flowFlows that contain high-density mixtures of hot, dry rock fragments and hot gases. sort of spans the volcanic spectrum from pyroclastic material to a lava fl â¦ ow. They flow down the volcano's side at tremendous speeds.
