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.
Are there choices? If there are choices what are they?
The answer is

Because many rivers run swiftly down int mountains.
Hope that helps
Answer:
- May be it was formed by faulting using the compression forces and hence formed due to the reverse faults formed
- Or, it was formed due to downwarping
Anyways it would have been better if you added the picture of the valley
