Pretty sure it's outer core, lower mantle because the inner core is solid iron
Answer:
Use materials more resistant to chemical weathering.
Explanation:
In the context of a warm and humid city, it is important to use building materials that are not extremely susceptible to chemical weathering. Buildings made of brick and/or iron and steel will survive much longer in the elements in a tropical condition than will a building made of wood or calcite. The latter is especially vulnerable to even the slightest amount of acidity in the rain and is easily dissolved.
Some changes are due to slow processes, such as erosion and weathering, and some changes are due to rapid processes, such as landslides, volcanic eruptions, and earthquakes.
