Burning of fossil fuels that release sulphur and nitrogen compounds into the air is identified as the major cause of acid rain in the united states.
<h3>What are the causes of acid rain?</h3>
- Acid Rain is created when sulphate and nitrogen oxides from the atmosphere react with rainwater and fall as a result.
- Sulphur and nitrogen particles that mix with the wet elements of rain are the main causes in the production of acid rain.
- Due to air pollutants, notably the excessive levels of sulphur and nitrogen released by machinery and industrial operations, acid rain is made up of water droplets that are extremely acidic.
- The emissions that are released from industries are man-made causes.
- The natural causes, such as lightning strikes in the atmosphere that release nitrogen oxides and volcanic eruptions that release sulphur oxide.
The complete question is :
What have the scientific studies identified as the major cause of acid rain in the United States?
a )chemicals still in the atmosphere from the asteroid collision with the earth
b) excess solar radiation due to the depletion of the ozone layer

The hypothesis can be defined as an educated guess, which is made by the scientists doing a scientific research.
In this case, the scientist want to test the presence of the limonite in the yellow rocks, So, proposed hypothesis should include the color of rock they want to observe and the posssible outcome, which need to be tested.
So, a proposed hypothesis can be:
<h3>The rocks, which have yellow color are made up of mineral limonite. </h3>
