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.
The answer is D. Gravity.
Gravity attracts objects to the surface of the Earth. Take a falling brick, for example, the brick has more mass, therefore, there is more attraction between the brick and Gravity. The brick is a solid object and is heavier as well.
Hope this helps! :)
Answer:
Sources of extraterrestrial rocky matter are cosmic dust and meteoroids, moon rocks.
Explanation:
- Sources of extraterrestrial water exist exclusively in ice layers, small amounts of water vapors. Ice giants like Uranus and Neptune have supercritical water oceans beneath the clouds.
- The presence of geysers on Saturn and Europa and Jupiter's of the moon contain vapors of water. Other glaciation evidence also helps proves the presence of oceans as the subsurface oceans came into consideration through the evidence collected from the past geological evidence.
- Venus had the premedial oceans like oceans on mars in the northern hemisphere. Comets also consist of large parts of icy waters due to there distance from the sun.
- The composition of iron and sulfur are the majorly two compositions of finding on the red planet of Mars.
