Molecules are moving because they have energy. As the liquid cools down, the amount of energy is reduced and the molecules start to move slower. When the water temperature reaches around 0°C, the molecules stick together and form a solid – ice. Even in this solid stage, the molecules are still moving – we just can’t see it.
Gyri form the top of the ridges, while sulci form the " valley" of the ridges.
The answer is ‘arteries are less flexible’. This is why the older you get the more predisposed you

become less sensitive hence these vessels become less responsive to blood
pressure changes.
