Answer:
Students have investigated what's going on in the fictional town of Westfield, they learned that the mysterious reddish-brown substance in the water is actually rust, which formed because of a chemical reaction between the iron pipes and the fertilizer substance in the water. It forms when iron and oxygen react in water or in moisture in the air. The reaction of iron and chloride underwater is also referred to as rust. Certain factors speed up the rusting process, such as salt in the water.
Explanation:
If climate and natural resources are favourable, they can benefit the economy. For example, if crops can grow easily and efficiently or if a lot of natural resources are available, those products can be sold and this the economy will rise.
I believe the answer is: <span>wedge-sector model
</span>wedge-sector model is a theory of land use that focus on outward expansion from the center of urban area.
The positive trait of this model is that it consider the potential growth after the center urban area has been fully developed.<span />
Less than 250,000 people currently depend on food foraging as their main source of income. The remaining foragers so frequently inhabit habitats (cold locations, woodlands, islands) where other methods of food production are not viable.
To forage is to look for wild food sources. It has an impact on an animal's fitness because it's crucial to its capacity for survival and reproduction. A subfield of behavioral ecology known as foraging theory examines how animals respond to their living environments by changing how they forage. There are two basic categories of foraging. The first is solitary foraging, which occurs when animals go hunting alone. The second is foraging in groups.
Today, fewer than 250,000 people rely on food foraging as their main source of income. Because other methods of food production are not sustainable in these environments (cold places, forests, islands), the remaining food foragers frequently live there.
