Igneous rocks form when magma or lava cools and hardens into a rock. Magma and lava are rocks that are so hot they move like a liquid. Magma is molten rock that is underground; lava is molten rock that is above the ground â and that is the only difference between them.A common igneous rock is granite.gneous rocks form when magma or lava cools and hardens into a rock.

In partial hydrogenation, the resulting fats are semi-solid at room temperature. In full hydrogenation, the oils become completely solid. The problem with partially hydrogenated oils is that they contain trans fat, which raises LDL (âbadâ) cholesterol, lowers HDL (âgoodâ) cholesterol and has other harmful effects. In contrast, fully hydrogenated oils, in essence, become saturated fatsâbut they contain no trans fat.
No because vegetable oils (e.g. olive, flax, sesame, canola oil etc) contain glycerol. Glycerol molecules give slipperiness and leave a greasy residue when applied to the skin. Essential oils are not greasy (unless mixed with vegetable oil). Vegetable oil is 100% fat but essential oils contain no fat. Whereas vegetable oils are mainly pressed from seeds, nuts, avocados, olives or the bran of grains, pure essential oils are steam distilled (with the exception of citrus oils which are cold-pressed) from plants.
