⭐Plastics.
Following are the correct options for this question:
- Build more windmills
- Develop cost-efficient solar energy
- Improve gas mileage in cars
- Reduce the use of nonrenewable energy sources
Any undesirable change occurs in the air due to addition of pollutants is called air pollution. The major air pollutants are sulfur dioxide which is released from the combustion of fossil fuels like coal, petroleum and from factories. Bedsides, sulfur dioxide dust and smokes are other pollutants. Building of more wind mills and developing low cost solar energy will reduce air pollution as they will provide clean energy and will reduce dependency on coal burning in thermal power plant. Improving as mileage in cars will also reduce emission of sulfur dioxide, hence reduce air pollution. Building of more wind mills and developing low cost solar energy are renewable source of energy, will reduce use of nonrenewable energy sources such as fossil fuels.
Answer:
Country which shares a border with the northernmost part of China : RUSSIA
Looking at the map I attached, you will notice that the northernmost part of China is to the North East between 120° E and 135° E. The country that borders this area is Russia.
Countries located between 105° E and 135° E lines of longitude:
Looking at the map and the lines of longitude circled, countries between these two lines of longitude are:
- North Korea
- South Korea
- Philippians
