Explore: Natural gas is a mixture of methane (CH4), ethane (C2H6), and other gases. Find two ways that natural gas forms. List the steps of the two carbon pathways below:

1. Atmosphere ⇒ Ocean ⇒ Marine Plants ⇒ Sediments ⇒ Natural Gas .

2. Atmosphere ⇒ Land Plants ⇒ Natural Gas.

Explanation:

Hello,

In this case, it is widely known there are two ways in which natural gas is formed:

1. Atmosphere ⇒ Ocean ⇒ Marine Plants ⇒ Sediments ⇒ Natural Gas .

In this one, the carbon dioxide in the atmosphere, is able to get through the ocean and in touch with marine plants which have the capacity to undergo photosynthesis and yield sugars which are subsequently fixated in the soil as sediments containing fossil fuels, coal and/or natural gas.

2. Atmosphere ⇒ Land Plants ⇒ Natural Gas.

In this one, the carbon dioxido also in the atmosphere is captured by the land plants which use it to undergo photosynthesis and subsequently fix it into the underground as fossil fuels, coal and/or natural gas as well.

Best regards.
