Answer:
Interrupt the long winter nights with a brief period of light.
Explanation:
Long day plants, also called short night plants, flower when the dark period is equal or less than the critical period specific for the species. These plants normally flower in summers when nights are short and days are longer. Winters have a long dark period and do not support flowering in shirt night plants.
A continuous dark period is critical for flowering. A short night plant can flower in winters (having longer dark periods) if the dark period is interrupted by exposing the plant with a flash of light. To make short night plants, such as iris to flower in winters, the plant should be given short period of light after completion of critical dark period.
Fracking collects natural gas that forms when organic matter is compressed under great temperature and pressure.
<h3>What is natural gas?</h3>
Natural gas is a mixture of gaseous hydrocarbons associated with petroleum deposits; mostly methane with smaller amounts of ethane, propane and butane; principally used as a fuel.
Natural gas is formed by the combination of compression and high temperature causing the carbon bonds in the organic matter to break down.
Therefore, it can be said that Fracking collects natural gas that forms when organic matter is compressed under great temperature and pressure.
