Water does not have layers. It is a single compound made up of two hydrogen atoms and one oxygen atom, known chemically as H2O.
Jupiter has 3 layers of clouds.
Country roads are often made of gravel because it is a cost-effective and low-maintenance option for rural areas with lower traffic volumes. Gravel roads can handle heavy loads and weather fluctuations better than paved roads, making them a practical choice for many rural communities.
7-8 layers
they were smart by building their roads with several layers of construction with proper drainage at the sides.

Heterogeneous systems can have varying numbers of layers depending on the specific context, such as in computing, material science, or geology. For instance, in a heterogeneous neural network, there can be multiple layers, including input, hidden, and output layers. In material science, a heterogeneous material may consist of several distinct layers with different properties. Therefore, the number of layers is not fixed and can differ widely based on the application.

The roads that the Tudors used were built by the Romans, and many roads that we have in the UK today, follow the same original foundations

Roman roads were remarkable for their engineering and durability, often built with multiple layers for drainage and stability. They featured a straight design that facilitated efficient travel and military movements across vast distances. These roads connected the Roman Empire, promoting trade and communication, and many are still used today. Their construction techniques set a standard for road-building that influenced future civilizations.
It's not about how many layers of clothes they wear, it's how the layer is made. In Antarctica, each layer of clothing is usually several other layers stitched together to keep as much heat heat as possible. It also depends on what material is used. During my year at South Pole Station, my outdoor clothing would be a parka, button-in liner, wool shirt, thermal underwear. The parka had a outer shell, insulating filler, inner shell - so that is 3 layers right there. The liner was also 3 layers. So there were usually 8 layers of material plus trapped air pockets between my skin and the very cold environment. It was about the same for the footwear.
