The correct option is B. The newest crust on earth is located at the actual site of the floor spreading and as new crusts are formed they replace it. Thus, the older the crust the farther it is from the mid ocean ridge.
Sea floor spreading is a geological process in which tectonic plates splits apart from one another. It occurs at divergent plate boundaries.
Events of the light-dependent reaction of photosynthesis starts with the absorption of sunlight and ends with ATP production.
<h3>Events of light-dependent reaction</h3>
- In the first step energy is absorbed from the sun and then water is broken down.
- Hydrogen ions of the water molecules are transported across the thylakoid membrane.
- NADPH is produced from NADP+.
- Hydrogen ions diffuse through the protein channel.
- ADP turns into ATP.
