Stromatolite fossils are the oldest known fossils<span>, that formed 3.5 billion years ago when the environments of Earth were too hostile to support life as we know it today. They </span><span>are layered mounds, columns, and sheet-like sedimentary rocks</span><span>
Stromatolite fossils indicate that </span>life must have arisen quite a bit earlier, perhaps 3.9 billion years ago.
I am not sure but does it not already do that. Because i think it goes both ways so we can get sun <span />
How much carbon dioxide is produced when different fuels are burned?
Different fuels emit different amounts of carbon dioxide (CO2) in relation to the energy they produce when burned. To analyze emissions across fuels, compare the amount of CO2 emitted per unit of energy output or heat content.
Pounds of CO2 emitted per million British thermal units (Btu) of energy for various fuels:
<span><span> Coal (anthracite) 228.6</span><span> Coal (bituminous) 205.7</span><span> Coal (lignite) 215.4</span><span> Coal (subbituminous) 214.3</span><span> Diesel fuel and heating oil 161.3</span><span> Gasoline 157.2</span><span> Propane 139.0</span><span> Natural gas<span> 117.0</span></span></span>
