Answer:
The air is clean and dry, not flooded with city lighting)
Answer:
Correct choice: They move side to side
Explanation:
<u>See below verification of given answer choices:</u>
They move side to side.
- <u>Yes,</u> they are produced through side by side motion of particles.
----------------------------------------------
They arrive before P waves.
- <u>No</u>, they are secondary waves, they are slow and arrive after P waves.
----------------------------------------------
They travel through liquids.
- <u>No</u>, they travel through solids and only liquids with high viscosity.
----------------------------------------------
They occur at Earth’s surface.
- <u>No</u>, they occur at inner core of Earth
The Earth is roughly a sphere. The Earth is an irregularly shaped ellipsoid.
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.
The earth is tilted because of the magnetic fields correlation with the sun
