Polyunsaturated fats are lipids in which the constituent hydrocarbon chain possesses two or more carbonâcarbon double bonds. Polyunsaturated fat can be found mostly in nuts, seeds, fish, algae, leafy greens, and krill.
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 a volcano erupts, it spews out molten rock, which is called lava. It 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.t is liquid in form and is extremely hot.
