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.
There's three types of plate boundaries:
- Collision plate boundaries (where two or more plates of the same density collide )
- Adjacent plate boundaries (where two or more plates slide against each other)
- Subduction plate boundaries (where one or more plates with lesser density are subducting below the the plate that has bigger density).

Answer:
coniferous forest or boreal forest
This biome typically has short, wet summers and long, cold winters. Precipitation is moderate in the taiga. It gets plenty of snow during the winter and plenty of rainfall during the summer.
Answer:
1. Compaction occurs where pressure is placed on loosely packed sediment. The volume of the sediment is reduced and water is squeezed out.
2. Cementation occurs when mineral-bearing water circulates among the grains, hardens, and cements the sediment grains together. This process is most effective when lithifying sand and gravel-sized sediments.
