How do materials move within the earth.
statuscvo [17]

The new materials from the center of the Earth rises, so the hardens and pushes older pieces of the Earth away from each other, which causes the movement of materials.

<h3>How do materials move within the earth?</h3>

The Earth's thermal energy is the main cause of the movement of materials within the earth surface. The Large continent-size plates moves slowly about the Earth's surface, which is driven by the thermal energy. The Convection currents transfer hot, buoyant magma to the lithosphere's layer at plate boundaries and hot spots. Convection currents also transfer denser, cooler material from the crust to Earth's interior through the process of subduction.

So we can conclude that: The new materials from the center of the Earth rises, so the hardens and pushes older pieces of the Earth away from each other, which causes the movement of materials.

In order for a fat molecule to be saturated, it must have what characteristic?
marin [14]
Fat (lipid) molecules are made up mostly of long chains of carbon atoms.
For a fat molecule to be considered saturated, the carbon chain must have only single bonds between them. 
Schematically, they look like  -C-C-C-C-  ...

If the carbon chain contains one or more double bonds, such as  -C=C-C-C, then the given lipid molecule is unsaturated.

If a lipid molecule (fatty acid) contains exactly one double bond in its chain, and the rest are single bonds, it is then called monosaturated.  It is a more healthy food source than saturated fats.

Saturated fat are generally solid at room temperatures.  Examples include lard, butter, mostly from animal sources.  However, coconut oil (solid at room temperatures as well) is a saturated fat.
