Astronomy and other space sciences

Question 1
The composition of the solar system is the sun and the planets. The following observation were made to show how the sun and the planets were formed separately and synchronized to form the solar system as shown by Hofmeister & Criss (2012). The nebula meaning clouds and dust was observed to have undergone various transformation to create the sun and later the planets. The dust is warm formed of molecule and hydrocarbons as revealed by a study of the Orion Nebula. A dense cloud has gravity and is forced to flop onto itself. The solar system is believed to have originated from a collapsed cloud that could have been one million times larger than the current solar system as indicated by Hofmeister & Criss (2012). The planets were formed from the remnant cloud and dark dust that collapsed into a disk. The planets were formed around the sun, and the solar system was formed.
Question2
Pluto and other such-like bodies are referred to as dwarf planets as shown in McKinnon, (2015). For an object to qualify to be named a planet according to IAU definition, it must be in its orbit around the sun, it must have a spherical shape, and it must clear any object neighboring its orbit. The first two qualifications have been met, but the third is not since it is not the dominant gravitational body along its orbit, which explains the phrase clearing the neighboring of its orbit.
Question 3
The geological process includes volcanic eruptions, erosion, and earth quacks this process create forces that modify the Earth also living creatures play a significant role in the change Egholm, (2013). The forces could be constructive and destructive, and both alter the earth’s landscape. On the other hand, even a 1000 decades is relatively a short span to be considered for a geological prediction. For instance, erosion will take a very long period sometimes the activity is un- noticed when it is acting to reduce a mountain ranges. The earth quacks and tsunamis are responsible for the destruction of ocean valleys bringing water into the land that has been developed and destroying it. For instance, there have been cases of the submerged cities dating many millions of years ago. Currently, the ocean floor is encroaching in coastal cities and according to prediction they will submerge in future and people will stop living in these towns and the civilization will stop Rona, Boström, Laubier, & Smith, (2013). .
Question 4
The asteroid impact wiped from the faces of the earth more than ¾ of the species Chapman, (2013). .the dinosaurs are believed to have been among the wiped animal community, they were huge carnivores that could probably have eaten the rest of animals including man. There would be probably no civilization like the one currently being experienced.
Question 5
The other planets apart from planet earth must be having other creatures or probably other forms of human beings with a strange feature for adaptation on their planet. There must be plants and other wild animals in those plants some could be vicious, and some could be friendly in nature.
Question 6
Recently there has been a discovery of over 300 exoplanets named hot Jupiter. K2 mission data was used to identify these hot Jupiter and have been used to explain how planets form and how they make up the solar system although they don’t orbit the sun. The exoplanets have been named hot Jupiter due to their proximity to the sun and due to their large size Vanderburg, (2015). Exoplanets are any planets that have its orbit away from the solar system; they orbit other stars and not the sun as shown by Schneider, Dedieu, Le Sidaner, Savalle, & Zolotukhin (2011).
