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.
However, a small amount of trans fat is found naturally, primarily in some animal-based foods. Essentially, trans fat is made when hydrogen is added to vegetable oil -- a process called hydrogenation. Hydrogenation increases the shelf life and flavor stability of foods containing these fats.rans fat, like saturated fat and dietary cholesterol, raises the LDL (or bad) cholesterol that increases your risk for CHD. On average, Americans consume 4 to 5 times as much saturated fat as trans fat in their diet.
