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. 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).
The way lava flows can be described in terms of the size of the lava flow, the surface texture of the lava flow, and the structural makeup of the lava flow. If the lava features a continuous surface that is smooth, features ropy folds, and if the flow is thin in size, then it is described as a pahoehoe flow.t is liquid in form and is extremely hot. The force of the blast and the viscosity of the liquid causes lava to flow away from the volcano. The composition of lava affects the way it flows, the speed at which it flows, and the resulting rocks that develop when the lava cools.
