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.
A volcano is a hollow vent in the Earth's surface, through which hot, molten rock, called magma, along with some gases and hot ash, oozes out from the Earth's interior. Magma erupting from a volcano is called lava.This magma is stored in the interior of the Earth in a sort of a large reservoir known as magma chamber.It is in this chamber that the formation of magma takes place by continuous melting of solid rock.Owing to this, the temperature of the magma chamber is immensely high.agma erupting from a volcano is called lava.
