Favelas, or informal settlements in Brazil, are typically constructed from a mix of materials such as bricks, concrete, wood, and metal sheets. These materials are often sourced locally and reflect the economic realities of the residents. Over time, the construction materials can change as families improve their homes, leading to more permanent structures made from better-quality materials or as urban development initiatives provide access to improved building resources. Additionally, changing environmental conditions and regulations can also influence the materials used in favela construction.

What are tailing materials IN MINING?
Those materials left over after the economically extractable portion of the mineral being mined has been separated from the ore.
How many man-made materials have been developed using science and technology?
Over 100
Why can lead and copper can be used as roofing materials?
Because they can last over 300 years If installed properly
Should your government mandate the use of materials that biodegrade once their useful life is over?
Yes. My government should mandate the use of materials that biodegrade once their useful life is over. Whether anyone will note, remember, or heed what the government mandates is another issue entirely.
What is a manual star-delta starter?
In manual star delta starter, the change over from star to delta does not happen automatically. The operator or user puts on the starter, and after few seconds he pushes a lever or handle to change over to Delta. In automatic method, change over happens from star to delta using an automatic preset timer.
How big are favelas?
Favelas vary significantly in size, with some encompassing just a few blocks and others stretching over several square kilometers. In Brazil, for example, large favelas like Rocinha in Rio de Janeiro can house tens of thousands of residents, while smaller ones may have only a few hundred. The population density can be extremely high, leading to crowded living conditions and a complex network of narrow streets and alleys. Overall, favelas are diverse in both their physical dimensions and the communities they serve.
How many people live in favelas?
According to the 2010 census, around 11. 25 million people across Brazil live in favelas, or shantytowns. This figure represents around 6 percent of the nation's population.
Who owns the favelas?
Favelas in Brazil are informal settlements that are primarily occupied by low-income residents, and they are typically not officially owned by anyone. While the land may be privately owned, many residents lack legal title to their homes, leading to a complex situation involving informal ownership and occupancy rights. Additionally, organized crime groups often exert control over some favelas, influencing local governance and services. Overall, the ownership structure is informal and varies significantly from one favela to another.
How does oxygen change other materials?
Oxygen can cause materials to oxidize, leading to corrosion or rusting in metals, degradation of organic materials, and combustion in some cases. Oxidation reactions with oxygen can alter the physical and chemical properties of materials, potentially weakening them over time.
Is Harry Hamer king of the Favelas?
Yes. he took over from his mother. He was her succesor. he then conquered Ratland and has a mansion with a BRICK WALL. There is also a map after his glorious nation in Modern Warfare 2.
How did the helicopters change over the years?
Helicopter design has changed every year. New components are used and new materials appear
How did China build the Great Wall of China?
The Great Wall of China remained the same but the materials they used changed over time. The Wall was first built using a mix of mud and gravel. Then over time when another emperor came he decided he wanted to change the materials. Instead of a mix of mud and gravel he decided to change it to bricks and stone.
Is the a creation of a canyon by a river a physical change?
Yes, the creation of a canyon by a river is considered a physical change. This process involves the erosion and transportation of soil and rock materials over time, leading to the alteration of the landscape. While the canyon's formation alters the physical structure of the environment, it does not change the chemical composition of the materials involved. Thus, it is classified as a physical change in the earth's geology.
Is diffusion of materials over long distance fast?
diffusion of materials over long distance is fast
What happens if one iron rod is rubbed with another iron rod?
what change will take place if two same materials are rubbed over each other
Is a dinosaur bone turning into rock over millions of years a physical change or chemical?
The process of a dinosaur bone turning into rock over millions of years is a chemical change. This transformation involves the replacement of organic materials in the bone with minerals through a process called fossilization, altering the composition of the original bone.
What is the fanctionaly graded materials?
Functionally graded materials are materials with properties that change gradually over their structure, rather than abruptly. This gradient in properties allows for better adaptation to different requirements or conditions in the material's application. FGMs are used in various engineering fields to improve performance and durability.
