Answer:
A. Geology
B. Computer aided designs
C. Dead organisms in the oceans
D. Helps in converting dead organisms into oil and gas
Explanation:
The oil and natural gas are buried under layers and this requires a good knowledge of "geology". Furthermore, equipments must be built to explore this oil and natural gas
Involvement of Technology has to do with "Computer aided models" being generated. Seismic surveys and satellites used to collect data.
Oil and gas began as dead plants and animals living in the ocean millions of years ago.
Role of sedimentation: the Organisms in the ocean died and went to the bottom of the ocean, where a layer of sediment would cover them. Over the years, alternating layers of dead organisms and sediments were formed. As the layers bottled up, the immense pressure and heat converted the dead organisms into oil and natural gas.
Well the altitde in <span>the atmosphere in which the stratospheric ozone can be found is 82 km. So the closest would be 70 km.</span>
