Explanation:
- Being a small and low mass star locate away from the sun in southern constellation being discovered in 1915 by Robert innings. Having an apparent magnitude of 11.3 having an Astronomical number of 12,950 from the orbital period of 550,000 years.
- Proxima Centauri is a red dwarf star with a mass of eight times that of sun, and an average density that of sun, more than 85%of the radiation is infrared and has the regular activity of starspots.

The literary meaning of the term Renaissance is Rebirth. This was the period in which people began renovating their old culture. Astronomy, geography, physics, mathematics, chemistry and anatomy were some of the fields in which major developments took place throughout the Renaissance period. Claudius Ptolemy in the late Middle Ages described that basis of astronomy as the geocentric model. During this time, Regiomontanus published notes in the form of a book known as "Theoricae novae planetarum". This "New Theorica" formed the basis of advanced astronomy during this period. Regiomontanus with the help of Constantinople carried forward the work of his teacher Purbach. He published the Epitome of the Almagest, in the year 1496 which became the basis of the Ptolemaic astronomy.
Nicolaus Copernicus also contributed to astronomy during the Renaissance period. Johannes Kepler and Galileo Galilei were the last two scholars of this period who gave an important contribution to this period.

Answer:
C. When the oceanic lithosphere, which is more dense, sinks and pulls the plate with it
Explanation:
Slab pull and other mechanisms are responsible for the motion of plates. Every tectonic plate is driven by mantle convection.
- Convection is a form of heat transfer in fluids.
- It is as a result of differences in density and temperature values.
- The oceanic crust is denser and colder.
- As hot magma from deep within the subsurface rises and move through cracks, the oceanic lithosphere is drawn down and deeper.
- This cycling between the cold lithosphere and hot rising plumes provides the mechanism that drives plate motion.
