This is only one part of the answer, but its important: high-altitude O2 absorbs much energy from the sun (including radioactivity), which forms the ozone layer. this process protects delicate molecules important to life - most notably dna
Answer:
Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense. The less-dense material rises, often forming a mountain or elevated area of the seafloor.
The order from smallest to largest would be:
H < C < N < O < Amino acid sequence < Globular Structure < Amino acid
The smallest should start from the elements. Among C, H, O and N, the lightest is the hydrogen, followed by carbon, nitrogen, then oxygen. You'll know this based on the periodic table. Next, is the amino acid sequence. This is the linear structure. Following is the globular structure which is the tertiary structure. The whole would be the amino acid.
