I would say D the Billingsella Corrugata, it IS in the oldest recorded time line, so by theory, it's the oldest (Don't quote me on that, I'm not %100)
Answer:
C. Airborne ash and rocks from a volcanic eruption remain suspended in the air for a long time before eventually settling to the ground in a new location far from the volcano.
Explanation:
Tephra deposits take many forms and shape, and their composition doesn't really matter either. The only thing that defines a tephra really is that it was ejected from the mouth of a volcano and fell on the ground where it remained intact (not merged with something else).
So, forms of tephra could be big boulders landing on the volcano's side or ashes that travel around the globe to land on the other side of the planet.
Answer:
You can use the mass-luminosity relation to find the star's lifetime in terms of just its initial mass. The lifetime = mass/luminosity × 1010 years is simply = (star's mass)/[(star's mass)p] × 1010 years = 1/(star's mass)p-1 × 1010 years. Remember that the star's mass is in solar masses.

An example of self-determination is the creation of Czechia and Slovakia.
Explanation:
The self-determination basically means that through the will of the people, a certain goal is a achieved usually(not always though) in peaceful manner, in this case ending a country and creating two new ones. Initially it was one country, Czechoslovakia. This country was composed of two main groups of people, the Czechs and Slovaks, and they peacefully collaborated and coexisted as a unit for several decades.
With the fall of the communism though, it became clear that the Czechs and the Slovaks have different ideals, and that they move into different directions. The people voted in a democratic manner to end the existence of Czechoslovakia, and to form to separate countries roughly divided with a border based on ethnic base. The formation of the new countries happened indeed and it was in totally peaceful manner, with the two countries retaining good relations.
Other examples of self-determination are:
- Creation of Macedonia, Serbia, Croatia, Slovenia, Bosnia out of Yugoslavia
- Creation of Austria and Hungary out of the Austria-Hungary Empire
- Creation of the Baltic states out of the Soviet Union
- Creation of Bulgaria, Greece, Lebanon etc. from the Ottoman Empire
