Planetesimals are small solid objects that form in the protoplanetary disk around a young star, while protoplanets are larger bodies that develop from the accumulation and collision of planetesimals. Planetesimals are the building blocks that come together to form protoplanets, and eventually, planets. So, planetesimals are like the "seeds" that grow into protoplanets.
It was Mercury.
Organisms in the same genus are most closely related to one another according to Linnaeus's groupings.
The planet Mercury originated from the protoplanet closest to the sun. It is one of the four rocky inner planets in our solar system.
The most popular theory of how a solar system is formed says that a giant cloud of molecular dust collapsed, forming one or more stars. Then a cloud of gas forms around the new star. As a result of gravity and other forces, the dust and other particles in this cloud collide and stick together forming larger masses. While some of these objects break apart on impact, a number of them continue to grow. Once they reach a certain size -- around a kilometer -- these objects are large enough to attract particles and other small objects with their gravity. They continue to get larger until they form protoplanets. Some protoplanets continue colliding and growing until they form planets while others stay that size.
one of the numerous small, solid bodies that, when gathered together, form a planet.
It was Mercury.
From debris following a collision of two planet sized protoplanets - one of which was early Earth.
They are not related by blood; they marry one another.
There is no way of knowing as in might of fallen in the dinosaur age and it was not recorded
it is related beacause it is one business function to another. They are all related one way or another because there are all in one orgnisation. Simples
A set of related scenes that follow one another could be called a sequence of scenes.
They are chronological
All living lifeforms are related one way or another.
Organisms in the same genus are most closely related to one another according to Linnaeus's groupings.
The study of how living and extinct organisms are related to one another is simple. This study is called evolution.
The Planetissimal Theory agrees with the Solar Disruption Theory. Because of the near collision of the Sun and another star, the Sun blew out some hot materials. These hot materials became parts of the star passing near the Sun. The Sun continued to blow large and small particles which became the planets, meteorites and other heavenly bodies. ---- Source: The World: History and Civilization
