Formation ofthe solar system notes
The formation of the solar system began from a large cloud of gas and dust called the solar nebula. As the nebula collapsed due to gravity, it formed a disc with the sun at the center. Planetesimals within the disc collided and accreted to form the planets. The nebular theory explained many characteristics of the solar system but did not account for all observations. The modern condensation theory expanded on this model and better explained features such as the asteroid belt and comets through processes like condensation and fractionation within the early solar system.
Solar system formation Claudia and Matthew
Our solar system formed over 4 billion years ago from a giant cloud of gas and dust. An explosion from a nearby star created this cloud, and gravity caused the cloud to collapse and spin, forming a dense, hot center that became our Sun. As the cloud flattened, particles stuck together in the outer regions to form planets like Jupiter, while only rocky planets could form near the Sun due to the intense heat. Over time, this process resulted in the current solar system containing the Sun and eight major planets.

The document discusses the structure and history of the universe according to cosmological theories. It describes how the universe began as a hot dense plasma following the Big Bang around 13 billion years ago. It formed into hydrogen and helium gases which later coalesced into the first stars and galaxies. The universe is still expanding today due to the initial force of the Big Bang and dark energy. The document also examines theories about different astronomical objects like galaxies, nebulae, quasars, black holes and planetary systems.
Earthand the solar system
The Big Bang generated a massive nebula of gases and dust that had a spinning motion and gravity. Dust particles in the nebula attracted each other to form denser matter, and collided at high speeds generating heat and forming the first stars, including our Sun, which is approximately 4.6 billion years old. Our solar system formed from the collapsing nebula and consists of the Sun and eight major planets, along with their natural satellites, asteroids, meteors, and comets.
Solar System Formation/Sun/Comets/Meteors
The document summarizes theories about how our solar system formed from a collapsing cloud of gas and dust. It describes how:
1) Our solar system likely began from a giant interstellar cloud that collapsed under gravity and formed a rotating disk, with a dense center that became the Sun and a surrounding disk that formed the planets.
2) The solar nebula disk varied in temperature by distance from the Sun, allowing different elements to condense into planetary cores near and far from the Sun, forming the terrestrial and gas giant planets.
3) Asteroids and comets are remnants from solar system formation and provide clues about its early history through observations and analysis of their composition and orbits.
Origin of the universe
The document summarizes the origin and composition of the universe. It begins with the Big Bang theory around 10-18,000 years ago which resulted in the formation of chemical elements like hydrogen, helium, and other compounds like water. The universe contains galaxies like the Milky Way galaxy, which contains our solar system centered around the Sun. The Earth rotates daily and revolves yearly around the Sun, causing seasons, and the Moon rotates and revolves around the Earth monthly, causing its phases. Gravity is the force that governs movement and interactions between astronomical bodies.
Planetarymotionhistoricalpeopleinastronomy 131204162554-phpapp02
The universe contains billions of galaxies, each with billions of stars. A galaxy is a group of stars held together by gravity, and the main types are spiral, elliptical, and irregular. Stars are formed from the collapse of large clouds of dust and gas, releasing heat and light through nuclear fusion. Our solar system contains 8 planets that orbit the Sun, including Earth. Copernicus first proposed the heliocentric model that planets orbit the Sun, with Kepler developing the laws of planetary motion. Newton later explained that gravity and inertia cause planets to follow elliptical orbits around the Sun.
Solar system formation[1]
The document summarizes the Nebular Theory of solar system formation. It states that the solar system formed from a rotating cloud of gas and dust remnants from a supernova. As the cloud collapsed under gravity, it flattened into a disc and spun faster. The center became very hot and formed the Sun, while the planets formed from accretion of planetesimals in the disc. The terrestrial planets are rocky, while the gas giants formed from condensation of ices and gases in the outer solar system. However, some observations of exoplanets do not fully match this theory.

05 (may) 5 & 6 16.3c the solar system - formation
According to geological evidence, the solar system formed approximately 4.6 billion years ago from a large cloud of dust and gas that collapsed due to gravity. A disk formed with the sun at the center, and planets formed farther out from the accretion of smaller particles that collided and stuck together. The locations and motions of the planets can be explained by this process, with gas giants forming farther out due to radiation pressure and terrestrial planets closer due to gravity. The moon's surface is covered in impact craters from asteroids early in the solar system's history and contains dark lava seas.
The Solar System
Our solar system consists of the Sun and eight planets, along with their moons, asteroids, comets, and dust and gases. It forms part of the Milky Way galaxy. The Sun is a large burning ball of fire that provides light and heat to Earth. The eight planets range from the small, rocky Mercury to the gas giants Jupiter and Saturn with their rings, to the icy planets Uranus and Neptune. Each planet has unique characteristics like size, composition, and time to orbit the Sun.
Origins of Our Solar System
The solar system formed from a giant cloud of dust and gas called a nebula approximately 5 billion years ago. As the nebula collapsed due to gravity, the densest parts compressed at its center to form the proto-Sun, while the remaining material flattened into a disk that would eventually form the planets. Over millions of years, dust particles in the disk collided and stuck together, growing into ever larger bodies including planets that began to orbit the newborn Sun. The inner terrestrial planets closest to the Sun include Mercury, Venus, Earth, and Mars, while the outer gas giants are Jupiter, Saturn, Uranus, and Neptune. In a few billion years, the Sun will grow hotter and expand, likely consuming the inner planets

Solar System Essay
The document is a solar system essay that discusses:
1) How our solar system formed from a giant gas cloud that collapsed under gravity 5 billion years ago, forming the sun and planets.
2) It describes the nine major planets - Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto.
3) It also mentions smaller bodies like asteroids and comets that orbit the sun.
Astronomy
The document summarizes key aspects of how scientists believe the universe began and evolved based on two major theories - the Big Bang theory and the Solar Nebula theory. It provides details on each theory, including that the Big Bang occurred approximately 13.75 billion years ago and resulted in the rapid expansion and cooling of an extremely hot and dense early universe. The Solar Nebula theory proposes that our solar system formed from a collapsing cloud of gas and dust that gave rise to the sun and orbiting bodies.
Earth in space
This chapter discusses the origin and evolution of the Earth and the solar system. It begins with an overview of the Big Bang theory for the origin of the universe and then describes the nebular hypothesis for the formation of the solar system from a primordial cloud of gas and dust. Key points include the differentiation of the Earth into a core, mantle and crust due to melting after accretion and the abundance of iron in the Earth's core versus the crust. The chapter also provides details about the different types of planets, asteroids, comets and meteorites that make up the solar system.
Ncert universe
The document provides information about celestial bodies like stars, constellations, and planets in our solar system. It discusses how ancient people used constellations like Ursa Major to determine directions. It describes the nine planets in our solar system, with Mercury being the closest to the sun and Pluto being the farthest, along with other objects like asteroids and meteoroids. The sun and these celestial bodies form our solar system. It also briefly mentions Neil Armstrong being the first person to walk on the moon.
Unit 4: How Our Solar System Formed
As stars die out and explode into supernovae, planets begin to form.

The Universe and the Stars
This document provides a summary of key concepts in astronomy, including the universe, galaxies, stars, planets in our solar system, and important historical astronomers like Ptolemy, Copernicus, and Galileo. It describes how stars are born from nebulae and die, as well as concepts like nuclear fusion, main sequence, and how our sun will eventually die. Important terms are defined like nebulae, constellations, blue giants, and red dwarfs. Historical figures that advanced our understanding of astronomy are also summarized.
The solar system
The document provides information about the solar system. It defines the solar system as a group of objects that interact with and orbit the sun. It describes the main objects in the solar system as planets, dwarf planets, moons, asteroids and comets. It explains that gravity is the force that causes objects to orbit the sun and interact with each other. It also discusses the differences between inner and outer planets, and how rotation and revolution cause seasons on Earth and variations in day length.
Our universe as a whole
The document discusses the major components of the universe including galaxies, stars, planets, comets and asteroids. It describes the formation of the universe through the Big Bang theory and provides details on key astronomical objects like nebulae, supernovae and constellations. Furthermore, it outlines our solar system and important facts about bodies like the sun, Earth and dwarf planets. The document also covers China's plans to develop an artificial moon and sun through nuclear fusion experiments.
The sun (more advanced)
Maybe too in-depth for most elementary students, but very good broad coverage for teacher background or more advanced students in elementary or middle school.
Solar System
1) The Solar System consists of the Sun and objects that orbit it, including 9 planets.
2) The planets follow elliptical orbits around the Sun due to the balance between gravitational pull and inertia.
3) There are several theories for how the Solar System formed, with the most widely accepted being the Nebular Hypothesis where a large cloud collapsed and spun to form a disk that condensed into planets.
Presentasi Sistem Tata SuryaㅡSolar System Explanation
The solar system formed over 4.6 billion years ago from a dense cloud of gas and dust that collapsed under its own gravity. As the central mass condensed to form the sun, the surrounding matter began to clump together through collisions to create the planets. The planets follow elliptical orbits around the sun, trapped by its strong gravitational pull along with other celestial bodies like asteroids, comets and moons. Our solar system resides within the Milky Way galaxy.

Module 1 origin and systems of earth
1. James Hutton established the theory of uniformitarianism, which states that the geological forces shaping Earth today are the same as in the past. He is considered the founder of modern geology.
2. Charles Darwin developed the theory of evolution through natural selection, which explained how species change over time in response to their environment.
3. Andrija Mohorovicic discovered the boundary between Earth's crust and mantle, known as the Mohorovicic discontinuity or "Moho".
4. Beno Gutenberg studied earthquakes and discovered that their waves can be used to investigate Earth's internal structure
our solar system.ppt
The document provides information about the geocentric and heliocentric models of the solar system. It discusses how ancient Greeks originally believed in the geocentric model where Earth is at the center, and how this view persisted for over 1500 years. Copernicus first suggested the heliocentric model where the Sun is at the center in the early 1500s. Galileo later provided evidence in support of Copernicus by observing the phases of Venus and moons orbiting Jupiter. Today the heliocentric model of a Sun-centered solar system is widely accepted.
A voyage through the universe. english
The document provides an overview of the universe and our solar system. It begins by explaining how vast the universe is compared to distances on Earth. It then discusses theories about the universe having no beginning and summarizes the Big Bang theory of how the universe began from a single point. The document describes our solar system and its planets, noting how perfectly suited Earth is for life while other planets are too hot, cold, or gaseous to support it. It concludes by emphasizing God's creation of the universe and planets in a state of perfect harmony and as a blessing for humanity.
My solar system
The Sun dominates the solar system, accounting for 99.86% of its total mass. There are 8 planets that orbit the Sun - Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. The inner planets are rocky, while the outer planets are gaseous. Planets differ in their distances from the Sun, sizes, temperatures, and orbital periods. Earth is the only known planet capable of supporting life.

Signatures of wave erosion in Titan’s coasts
The shorelines of Titan’s hydrocarbon seas trace flooded erosional landforms such as river valleys; however, it isunclear whether coastal erosion has subsequently altered these shorelines. Spacecraft observations and theo-retical models suggest that wind may cause waves to form on Titan’s seas, potentially driving coastal erosion,but the observational evidence of waves is indirect, and the processes affecting shoreline evolution on Titanremain unknown. No widely accepted framework exists for using shoreline morphology to quantitatively dis-cern coastal erosion mechanisms, even on Earth, where the dominant mechanisms are known. We combinelandscape evolution models with measurements of shoreline shape on Earth to characterize how differentcoastal erosion mechanisms affect shoreline morphology. Applying this framework to Titan, we find that theshorelines of Titan’s seas are most consistent with flooded landscapes that subsequently have been eroded bywaves, rather than a uniform erosional process or no coastal erosion, particularly if wave growth saturates atfetch lengths of tens of kilometers.
Mechanics:- Simple and Compound Pendulum
a compound pendulum is a physical system with a more complex structure than a simple pendulum, incorporating its mass distribution and dimensions into its oscillatory motion around a fixed axis. Understanding its dynamics involves principles of rotational mechanics and the interplay between gravitational potential energy and kinetic energy. Compound pendulums are used in various scientific and engineering applications, such as seismology for measuring earthquakes, in clocks to maintain accurate timekeeping, and in mechanical systems to study oscillatory motion dynamics.

JAMES WEBB STUDY THE MASSIVE BLACK HOLE SEEDS
The pathway(s) to seeding the massive black holes (MBHs) that exist at the heart of galaxies in the present and distant Universe remains an unsolved problem. Here we categorise, describe and quantitatively discuss the formation pathways of both light and heavy seeds. We emphasise that the most recent computational models suggest that rather than a bimodal-like mass spectrum between light and heavy seeds with light at one end and heavy at the other that instead a continuum exists. Light seeds being more ubiquitous and the heavier seeds becoming less and less abundant due the rarer environmental conditions required for their formation. We therefore examine the different mechanisms that give rise to different seed mass spectrums. We show how and why the mechanisms that produce the heaviest seeds are also among the rarest events in the Universe and are hence extremely unlikely to be the seeds for the vast majority of the MBH population. We quantify, within the limits of the current large uncertainties in the seeding processes, the expected number densities of the seed mass spectrum. We argue that light seeds must be at least 103 to 105 times more numerous than heavy seeds to explain the MBH population as a whole. Based on our current understanding of the seed population this makes heavy seeds (Mseed > 103 M⊙) a significantly more likely pathway given that heavy seeds have an abundance pattern than is close to and likely in excess of 10−4 compared to light seeds. Finally, we examine the current state-of-the-art in numerical calculations and recent observations and plot a path forward for near-future advances in both domains.

Microbial interaction
Microorganisms interacts with each other and can be physically associated with another organisms in a variety of ways.
One organism can be located on the surface of another organism as an ectobiont or located within another organism as endobiont.
Microbial interaction may be positive such as mutualism, proto-cooperation, commensalism or may be negative such as parasitism, predation or competition
Types of microbial interaction
Positive interaction: mutualism, proto-cooperation, commensalism
Negative interaction: Ammensalism (antagonism), parasitism, predation, competition
I. Mutualism:
It is defined as the relationship in which each organism in interaction gets benefits from association. It is an obligatory relationship in which mutualist and host are metabolically dependent on each other.
Mutualistic relationship is very specific where one member of association cannot be replaced by another species.
Mutualism require close physical contact between interacting organisms.
Relationship of mutualism allows organisms to exist in habitat that could not occupied by either species alone.
Mutualistic relationship between organisms allows them to act as a single organism.
Examples of mutualism:
i. Lichens:
Lichens are excellent example of mutualism.
They are the association of specific fungi and certain genus of algae. In lichen, fungal partner is called mycobiont and algal partner is called
II. Syntrophism:
It is an association in which the growth of one organism either depends on or improved by the substrate provided by another organism.
In syntrophism both organism in association gets benefits.
Compound A
Utilized by population 1
Compound B
Utilized by population 2
Compound C
utilized by both Population 1+2
Products
In this theoretical example of syntrophism, population 1 is able to utilize and metabolize compound A, forming compound B but cannot metabolize beyond compound B without co-operation of population 2. Population 2is unable to utilize compound A but it can metabolize compound B forming compound C. Then both population 1 and 2 are able to carry out metabolic reaction which leads to formation of end product that neither population could produce alone.
Examples of syntrophism:
i. Methanogenic ecosystem in sludge digester
Methane produced by methanogenic bacteria depends upon interspecies hydrogen transfer by other fermentative bacteria.
Anaerobic fermentative bacteria generate CO2 and H2 utilizing carbohydrates which is then utilized by methanogenic bacteria (Methanobacter) to produce methane.
ii. Lactobacillus arobinosus and Enterococcus faecalis:
In the minimal media, Lactobacillus arobinosus and Enterococcus faecalis are able to grow together but not alone.
The synergistic relationship between E. faecalis and L. arobinosus occurs in which E. faecalis require folic acid

- 1. NATURAL SCIENCES:THE EVOLUTION OF OUR UNIVERSE T SHUDE 219039888
- 2. OUTCOMES OF THE LESSON WILL BE AN OVERVIEW OF: The Big Bang theory The expansion of space and time How the sun holds all planets and moons into orbits The trend in the arrangement of planets and composition Earth being in the habitable zone allowing for the 4 major spheres
- 3. THE BIG BANG THEORY… Suggests that all matter was originally packed extremely tightly in a nucleus of high density which then exploded. The energy which burst out from the explosion came in the form of intense heat radiation. Radiation today is now in the form of the 7 known forms of radiation.
- 4. THE EXPANSION OF SPACE AND TIME In 1929, Edwin Hubble discovered that light coming from other galaxies increased uniformly with increased distance of that galaxy from earth. He then concluded that other galaxies were moving away from earth and our milky way galaxy which implied that every object in the universe is moving away from each other thus…THE UNIVERSE IS EXPANDING POST BIG BANG.
- 5. THE CONTRADICTION If galaxies are moving away from each other, why is it that the moon does not move away from the Earth or the Earth as the Sun? What holds them together?
- 6. THE SUN’S GRAVITATIONAL INFLUENCE ON THE PLANETS AND MOONS Just like any other star, our sun is one of 100 billion stars in the milky way which is one of 100 billion other galaxies out there. Each star has its own specific and unique structure and system of planets which are held by the star’s gravity which it less likely escapes.
- 8. Comparison between planets in the solar system Terrestrial planet Small Rocky Nearer the sun Shorter orbit Consists of heavy, metallic compounds Eg earth Gas giant planet Large Foamy Further away from the sun Longer orbits Consists of lighter, gaseous compounds Eg jupiter
- 9. PLANET EARTH’S UNIQUENESS The habitable zone is a region along any star system where the temperatures are not too hot nor cold to have water in liquid form to harbour chances of the existence of life. it is important because it enhances possibilities for a symbiotic relationship between the 4 major spheres…
