Answer: . all of the above
Explanation:
Science has benefited the society by contributing to wide areas of scientific fields like their contribution in medical science, invention of alternative sources of energy, and technological advances.
Medical science: Scientists have conducted many research in order to determine the cause of diseases and their possible diagnostic treatments.
New energy: Scientists have found out energy harnessing technology from renewable resources like water, sunlight and biomass which can meet the energy requirement of human society when conventional resources will not be available.
Technological advances: Scientists have contributed to the development of diversity of machinery which can reduce the human labor.
Idk the timeline but from largest to smallest, this hierarchy includes eons, eras, periods, epochs, and ages.
Going upward from the surface, it is the point where air ceases to cool with height, and becomes almost completely dry. More formally, the tropopause is the region of the atmosphere where the environmental lapse rate changes from positive, as it behaves in the troposphere, to the stratospheric negative one. Following is the exact definition used by the World Meteorological Organization:
The boundary between the troposphere and the stratosphere, where an abrupt change in lapse rate usually occurs. It is defined as the lowest level at which the lapse rate decreases to 2 °C/km or less, provided that the average lapse rate between this level and all higher levels within 2 km does not exceed 2 °C/km.<span>[1] for example</span>
