Answer: Ozone is considered as chief polluting gas.
Explanation:
The ozone is a ground level pollutant. It is a colorless gas. It causes irritation in the eyes and respiratory tract. It is one of the components of smog as it causes pollution in the atmosphere. It is produced by the two primary pollutants that are nitrogen oxides and volatile organic compounds when they react with the sunlight. The ozone makes the air irrespirable. It is the main cause of throat irritation, labored breath, pain in chest and also responsible for respiratory diseases. It reduces the body's ability against infection. The ozone depleting substances like aerosol, chlorofluorocarbon are widening the ozone depleting zone as halides present in these substances react with the ozone causing depletion. This allows the entry of harmful ultraviolet radiation penetrating the atmospheric layers.
Answer: subduction
Explanation: the oceanic plates sliding under continental plates form volcanoes
The Central American Vegetation/Land Cover Classification and Conservation Status consists of GIS coverages of vegetation classes (forests, woodlands, savannas, shrubs, grasslands, wetlands, rocks, sand, soils, inland waters, parks and reserves) for Central America, derived from 1-kilometer resolution Advanced Very High Resolution Radiometer (AVHRR) imagery. This data set is produced by Proyecto Ambiental Regional de Centroamerica/Central America Protected Areas Systems (PROARCA/CAPAS), a conservation partnership of the Central American Commission on Environment and Development (CCAD), U.S. Agency for International Development (USAID), International Resources Group, Ltd. (IRG), The Nature Conservancy (TNC), Winrock International (WI), and is distributed by the Columbia University Center for International Earth Science Information Network (CIESIN).
Answer:
c) age of one event in comparison with another
Explanation:
The relative dating is a commonly used method among the geologists, paleontologists, and archaeologist. This method is used for determining the order of events that happened in the past, or rather the age of an object in comparison with another object. This also means that it is not necessary for this purpose to determine the absolute age of the objects, but instead the age of one one of them is compared with another one, and we get to the relative dating of an object that is required.
C - South / Persian Gulf
The rivers both flow south to the opposite direction of the Black Sea. They’re also not near the Mediterranean Sea nor do they flow southwest to the Dead Sea, more so they flow to the Persian Gulf.
Hope this helps!
