<span>The state of matter in which particles are closest together is a solid. This is most easily described by thinking of it in terms of the solid being formed into a particular fixed shape, made possible by the fact the particles are packed tightly, whereas say, a liquid, has loosely packed particles and is free to flow and move (even looser in the case of gases and plasmas)</span>
I believe it’s C , People are burning too many fossil fuels .
<span> the atmosphere holds about 21 per cent oxygen. Over the Earth’s 4.6 billion year history, oxygen did not appear in the atmosphere until perhaps about 2.5 billion years ago. Since then, oxygen levels have fluctuated in tandem with global geological and biological events, such as mass extinctions.</span>
