The employment structure of a country depicts the majority demographics of the labor force in the country and the major labor sector of the country (primary, secondary or tertiary). The developing countries’ economy will have the majority of its labor force mainly in the primary labor sector (raw mineral extraction) while most developed country's labour force is mainly in the tertiary (service industry) sector.
The primary labor sector involves the use of more human labor and less use of machinery. This, therefore, raises the costs of production (and the costs of the goods) and little value-addition to the products. The profit margins are low. In tertiary labor sector, automation reduces costs of production and profit margins can be high without raising the costs of goods exorbitantly.
To calculate the slope, the formula is (y1-y2)/(x1-x2) , which in this case, the answer would be:

Answer:
Density is one of the most factors that play a key role in plate tectonic activities. Some of the ways in which density is important in the field of plate tectonics are as follows-
- The convergent plate boundaries are responsible for the creation of a subduction zone, where the high-density lithospheric plate subducts below the less dense one. It is because the heavier plate is comprised of heavy minerals thereby forming heavier rocks as a result of which its density increases. Due to these differences in density, there occurs a subduction zone.
- The divergent plate boundary forms where two plates move away from one another. This type of plate motion is responsible for the eruption of magma on the seafloor. As the plates diverge, the lithosphere becomes eventually thin, and with more progressive spreading, the magma comes out to the seafloor. This is because the hot magma is less dense, and forms convection cells as they rise upward. This is how the density helps in the upwelling of magma at the mid-oceanic ridge in a divergent plate boundary.
- When there collide two plates of equal densities, then it gives rise to the formation of huge mountains, because neither of them is heavy to get sink. So it uplifts the crust, forming a sandwich-type pattern.
