<u>RESEARCH ON PROXIMA CENTAURI:</u>
- Robert Innes discovered proxima centauri which is closest to the Sun in 1915 and it is believed to be 4.85 billion years old.
- Innes used a blink comparator though later he was in competition with another scientist named, Voute who provided theoretical values pertaining to the star more accurately than Innes.
- The recent findings found a planet which is located close to the Proxima Centauri making it the closest planet to our Solar System.
Answer:
The crust size remains constant because the older crust is melted at subduction zones.
Explanation:
The crust is constnatly created on Earth, but the crust is constantly getting destroyed as well. This situation leads to the total size of the crust being roughly at the same level, or rather constant, as one side a new one emerges, while at the same time, on the other side it gets destroyed.
The vast majority of the new crust is formed where there are divergent plate boundaries. Here, a gap opens up between the plates that move away and magma is constantly rising to the surface and creates new crust. When it comes to the destruction of crust, it occurs at subduction zones. Here, one plate moves below another plate, and as it does it reaches the upper mantle where it gets melted and recycled because of the high temperatures and pressure.
