Around 1800 (plus or minus about 5 years) is when it was estimated that the world's population had reached 1 billion.
It’s high winds or high humidity
Answer:
c) The planetoid is being attracted toward another massive object.
Explanation:
We can rule out a, the planetoid is travelling through space, friction is effectively nonexistent. B can be ruled out as well, as there is nothing in space that could naturally repel a planetoid. D is also implausible, as the question says the planetoid slows down for a certain period in its orbit, suggesting this behavior is repeated. Option c is incredibly likely, as the planetoid is far from the sun, a large mass, possibly far smaller than the sun but also far closer to the planetoid, could have the effect described in the question.
Answer:
The answer would be D, Both developed and developing countries have had significant negative impacts on the environment
Explanation:
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.
