In this activity, we will explore the world’s climatic regions. Climate classifications, for example the Köppen climate classification, are based on empirical data such as monthly and annual averages of temperature and precipitation. The Köppen climate classification, and several systems modified from it, recognize five major climatic types (tropical, dry, moist midlatitude mild winters, moist midlatitude cold winters, and polar). These are further subdivided into more refined subcategories. After completing this activity you should be able to: Identify the major climate categories and subcategories of Earth.
Locate them on a world map.
Explain the temperature and moisture criteria used to define these categories and subcategories.
In North America, which of the following climate zones fall within areas that primarily average between 40 and 59 inches of precipitation annually or higher?
a. Humid subtropical, moist all year, hot summer (Cfa)
b. Tropical, subtropical hot desert (BWh)
c. Humid continental, hot summer (Dfa, Dwa, Dsa)
d. Midlatitude cold steppe (BSk)
e. Subarctic, cool summer (Dfc, Dwc, Dsc)

marginal cost is a microeconomic measure that us to evaluate the extent to which the level of production of a good is sustainable in accounting, that is, to how many quantities the company plans to profit from the production of the good.

the concept of marginal cost is simple, it means the cost of producing one more item. for example, in the case of pies, the marginal cost is the cost of producing one more pie than those that have already been produced.

it is important to understand that productive activity influences marginal cost. the marginal cost of some goods can be very high, while others may be insignificant. for example, the marginal cost of producing an extra plane is very high. already the marginal cost of a water company to provide 1l more water is derisory.

in the case of pies, the cost involves the inputs, the labor and the fixed cost, which involves the fixed space of the bakery. the level of production initially has the marginal cost decreasing because there is space and manpower available. however, to produce more you have to hire more workers and buy more inputs. if physical space is limited, workers will conflict with places, inputs and their productivity will decrease, meaning there is an optimum point of production for each level of space and manpower. from this point on, the productivity of the workers will be getting smaller because of lack of space, so that the marginal cost of producing one more pie will be increasing. so, although you have not posted the chart, but if you have the answer, you can see that my explanation goes according to the marginal cost curve that will increase from the 4th pie, answer (c).
