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.
Itâs there that the liquid rock waits to find a way through to the surface, causing a volcanic eruption. In most cases, the crater is usually closed after the eruption by cold, hard lava. Thrihnukagigur volcano is a rare exception to this, because the magma in the chamber seems to have disappeared.
