Which items describe possible solutions to air pollution?
Radda [10]

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 technique called radiometric dating is based on
Dima020 [189]

Answer:

D) the steady, clocklike decay of certain radioactive isotopes over time.

Explanation:

Geologists use radiometric dating to estimate how long ago rocks formed, and to infer the ages of fossils contained within those rocks.

For example, when rocks are formed, such as igneous rocks (formed when molten rocks cools), certain radioactive atoms are trapped inside the rocks during this formation process. Then these radioactive atoms decay over time.

The age of the rock can be estimated by comparing the occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay.

From the options;

A) this is about the formation of the radioactive molecules and not about radiometric dating

B) this is radiocarbon dating (cabon dating/carbon-14 dating)

C) the <em>assumption </em>is wrong since the radioactive isotopes decays not accumulate.

D) the corect option as I explained earlier.
