INTRODUCTIONThe modern science has its root in fundamental questions related to the origins of Earthand life. The solar system is made up of different types of planets that the outer planets areJupiter, Saturn, Uranus and Neptune. This can be distinguished from the inner planets by theirlarge size and low density. The present assignment is based on different question regarding Earthand science. In this report, the importance of each questions is explained. Along with this therelationship between each questions is discussed. Apart from this, comparison is done betweenthe research in the book and the new research which has been done at present. Main body1. ORIGINSHow did Earth and other planets formThis question is important because it states the way Earth and other planet formed. TheSolar system is with its inviting geometric patterns and there wide variety of planets and moons.This make given question more important because new observation was made on Earth that hasretained a life giving inventory of volatile substances, includes air and water. This question isone of the challenging and important questions about the Earth's formation. It helps inunderstanding the inner planets formed (Kumar, Kuribayashi & Ishikawa, 2013). Question 2: What happened during Earth’s “dark age” (the first 500 million years)? The importance of this question is that it help in gaining information of “dark age”. AMars sized planet was hit with sun. This collision added so much heat to Earth due to whichentire planet is dissolved . There are many clues regarding this time period are compiled and helpin learning and gaining new information from ancient crystal of zircon on Earth. Question 3: How did life begin? The starting of life is one of the most interesting, difficult and abiding question inscience. However, this question not give relevant answer because life in Solar System arose abillion of years ago, but it helps in understanding where, when and what for it first appeared(Bojarczuk, Buchanan & Ragnarsson, 2008). At early time earth surface seems to be differentfrom today's and one of the critical challenge is to identify chemical building available to earlylife and its physical environment.1
Relationship between this questionsThere are three questions in origin chapter, the two questions that are regarding to the origin ofearth and other planets and other one is related to origin of life are separated by the third whichdeals with Earth's earliest history.2 EARTH’S INTERIOR Question 4: How does Earth’s interior work, and how does it affect the surface?This question is important because it assists in enhancing the knowledge regarding theEarths interior work and its effect the surface. This question addresses deep Earth dynamicalprocesses, from the inner metallic core at the Centre of the convecting mantle to the volcanoes atthe surface. When the planet is geologically active, thus evidence of this activity grinds to a halt,due to which planet surface stops regenerating (Honma, Koshiba & Komatsu, 2008). Withouthaving knowledge it becomes difficult to know earth internal process, It becomes difficult todeduce the Earth's surface environment which was in the past or predict what it will be in thefuture. Question 5: Why does Earth have plate tectonics and continents? This question is essential because Earth has tectonics in the first place and this questionwill help in understanding the way it closely related to other specific aspects of Earth. From thenew data and information it becomes easy to know that climate and erosion play significant rilein building and shaping mountain range (Montemor, & Ferreira, 2008). Question 6: How are Earth processes controlled by material properties? The given question is important for creating a good understanding related to the earthprocess controlled by material properties. Therefore, for understanding this key process are thebasic physics and chemistry of planetary materials (Maruyama & Santosh, 2008). Along withthis the high pressure and temperature this are the challenges which are met with the newresearch tool. Relationship between these questionsThere is relationship between these questions such as resolving the critical questions related toplanetary evolution will require enough knowledge of planetary materials and the way theyimpact convection (Question 6), 2
