Answer:
A population pyramid is a graph that allows us to see the gender and age structure of a population. There are different shapes to the pyramids which tell us different things about the population of the country. It is often useful to divide population pyramids into 3 distinct age groups or COHORTS- 0-15 or the Young, 16-65 or the working age and 65+ as the retired sectors of the population. Knowing the percentage of people in these sectors can allow us to calculate a Dependency Ratio. This is the ratio between those of working age and those of non-working age. The no-working age are known as DEPENDENTS because they depend upon the working age people to provide for their needs.

Explanation:
The Industrial Revolution changed working conditions for people by putting them at more danger of injury from the machinery as well as pollution. People no longer had to rely on their own labour, animals or passive energy ( via rivers) and they could produce things at the industries own rate often at the expense of the worker. All in all the working conditions were worsened but later on there were protections put into place that would protect such as mandatory safety precaution such as doors opening outward (Triangle Shirt Factory) as well as child labour laws
Answer:
<u>B surface map; isobaric chart</u>
Explanation:
- A surface map is a map used in weather analysis to view the geographical areas from the weather perspectives through the use of ground-based stations. This map shows all the surface phenomena like the winds, rainfall and cloud cover, etc.
- The isobars show the variation in atmospheric pressure over the high and lower pressure areas when the air pressure is lower the bars are spaced and when the pressure is higher the bar is closely spaced.
- Thus the isobaric charts show us the areas that are well defined in terms of equal areas of atmospheric circulation of the map. Displacement of warm and cold air also tells us the type of formations of pressure formations
