The document summarizes the currently accepted theory of planetary formation called the planetesimal theory. It states that:
1) A gas and dust nebula received an expansive wave from a nearby supernova, causing it to rotate faster and collapse into a disk with particles accumulating in the center to form our Sun.
2) Small bits of matter in the disk collided and joined together to form larger planetesimals, which eventually collided to form the planets through accretion.
3) The inner planets like Earth took longer to form than the outer gas giants because of higher temperatures and less abundant gases and rock particles in the region between the freezing line and rock line.
How fast can an atmosphere travel round it's planet? "Normal" rotation on Ear...wonderdome
Wouldn’t it be wonderful to live on a planet with a non-rotating atmosphere to be able to travel places by just jumping into the air and hovering long enough? Sounds fantastic, right? The problem is, when a planet turns and the air does not, things get really windy. As in “a thousand miles per hour wind speed “ windy.
Luckily for us, we don’t experience it here on Earth. The Earth’s atmosphere travels in sync with our planet and completes one turn around its axis in roughly 24 hours. Phew!

Theory of Planetary System Formation The mass of the presol.pdfadislifestyle
Theory of Planetary System Formation The mass of the pre-solar molecular cloud played the
largest role in terms of how the solar system formed. It might have begun with a 100 solar mass
cloud approximately 1 to 2 light years in diameter. It's possible that mutual gravitational attraction
between cloud particles was too weak to start the process. When gravity is too weak, the only
other force strong enough to bring a significant number of particles together is the electromagnetic
force. Barring that, perhaps a nearby shockwave from a supernova explosion caused the initial
motion of material: but once started, gravity took hold, causing the inevitable collapse. The
process it underwent followed a pattern that scientists believe is mirrored everywhere a star exists.
In this activity, you will put the solar system formation process parts in order from the beginning. 1.
Planetesimals accreted material until they became large enough to form planets. 2. Gravitational
potential energy of the collapsing gas cloud was converted into thermal energy. 3. Collapsing gas
cloud rotated faster as the collapse continued due to conservation of angular momentum. 4.
Planetesimals were massive enough to have a gravitational field sufficient to attract additional
nearby objects. 5. The random motions of material in the collapsing gas cloud were reduced to the
final motion of the material rotating in a disk. 6. The inner parts of the continuing, flattening cloud
free fell into the growing object at the center. 7. Continued motions brushed smaller particle grains
against larger grains. As this electrostatic "sticking" occurred, the particle grains became larger. 8.
Cloud of molecular gas started to collapse due to gravity or other astrophysical process. Use the
number of the process to order them from earliest to latest (left to right).Temperature and
Formation of Our Solar System Temperature was the key factor leading to the state distribution of
various objects made of different elements and compounds. The graph below shows the
temperature (expressed in kelvins) at different distances from the Sun (expressed in AU ) in the
solar system during the time when the planets were formed. To produce a linear plot, in the usual
sense, the vertical axis is inverted so that temperature goes from high to low starting near the Sun.
Use Figure 1 to fill in Table 1 with the formation temperatures for each planet, including the dwarf
planet, Ceres.Aktranomy 1511 Laboratory Manua! Bond albedo refers to the total radiation
reflected from an object compared to the total incident radiation from the Sun. The geometric
albedo refers to the amount of radiation equally reflected in all directions at all wavelengths off an
object. It is clear that a wide range of planetary formation temperatures existed in the early solar
system. The temperatures at which different compounds form or for which elements have physical
state changes will vary. Since the majority of material in the molecular cl.

Galactic Context
The Solar System is located in the Milky Way galaxy, a barred spiral galaxy with a diameter of about 100,000 light-years containing about 200 billion stars. Our Sun resides in one of the Milky Way's outer spiral arms, known as the Orion Arm or Local Spur. The Sun lies between 25,000 and 28,000 light years from the Galactic Centre, and its speed within the galaxy is about 220 kilometres per second, so that it completes one revolution every 225–250 million years. This revolution is known as the Solar System's galactic year. The solar apex, the direction of the Sun's path through interstellar space, is near the constellation of Hercules in the direction of the current location of the bright star Vega. The plane of the Solar System's ecliptic lies nearly at right angles (86.5°) to the galactic plane.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
2. ORIGIN OF THE SOLAR SYSTEM
THE CURRENTLY ACCEPTED THEORY TO EXPLAIN THE FORMATION OF THE
SOLAR SYSTEM, AND THE OWN EARTH IS THE THEORY OF THE
PLANETESIMALS:
1. A GAS AND DUST NEBULA, FLOATING IN SPACE WITH VERY SLOW
MOVEMENTS BETWEEN ITS PARTICLES TILL IT RECEIVED THE EXPANSIVE
WAVE OF THE EXPLOSION OF A NEARBY SUPERNOVA.
2. THE NEBULA BEGAN TO ROTATE MUCH FASTER, AND TO COLLAPSE IN A
SINGLE PLANE.
3. IN THE CENTER OF THE NEBULA, THE ACCUMULATION OF MATTER AND
THE CONTINUOUS SHOOTS INCREASED THE PRESSURE AND THE
TEMPERATURE, ALLOWING THAT THEY WILL BEGIN TO NUCLEAR
REACTIONS. THAT WAS BORN OUR SUN FROM A PROTOSOL.
3. ORIGIN OF THE SOLAR SYSTEM
4. OUR CENTRAL STAR ATTRACTED 99.85% OF THE MATTER AND GAS OF
THE SYSTEM, BUT THE REST WAS ABLE TO SEPARATE AND THROUGH
THE ROCK LINE, WHERE THERE WAS PIECE OF MATTER AND EVEN
FURTHER, AFTER THE FREEZING LINE GASES WERE SOLIDIFIED AS
WATER VAPOR, METHANE, ETC.
5. SMALL BITS OF MATTER, THEY WOULD BEGIN TO COLLIDE WITH LITTLE
VIOLENCE AND JOIN IN AGGREGATES OF GREATER SIZE CALLS
PLANETESIMALS, WHICH WOULD IMPACT THEMSELVES, INCREASING
SIZE UNTIL FORMING THE PLANETS.
6. THIS PROCESS WAS FASTER IN THE FORMATION OF THE EXTERNAL
PLANETS BECAUSE THERE WERE MUCH MORE GREAT AMOUNT OF
FLOATING PARTICLES. ONCE THESE PLANETS REACH A DETERMINED
SIZE, THEY BEGIN TO ATTRACT THE GAS AND MATTER THAT SURROUND
THEMSELVES WITH GRAVITATORY FORCES, BECOMING GASEOUS
GIANTS (EXTERNAL PLANETS).
4. ORIGIN OF THE SOLAR SYSTEM
7. IN THE AREA LOCATED BETWEEN THE ROCK LINE AND THE FREEZING
LINE, WHEN THE TEMPERATURE IS GREATER, GAS IS SCARCE AND THE
ROCK PARTICLES IN SUSPENSION ARE LESS ABUNDANT, SO THAT IT
TAKES MUCH MORE TIME TO FORM THE PLANETS FROM
PLANETESIMALS. IN ADDITION TO THE NO GAS, THERE CAN ONLY
ATTRACT ROCK FRAGMENTS, SO THE INTERIOR PLANETS WILL BE LESS
SIZE THAN THE EXTERNAL PLANETS.
8. THE EARTH IN ITS FIRST STAGES WAS ACCOMPANIED BY ANOTHER
PROTOPLANET CALLED CEIA, FINALLY COLLISED, WINNING THE EARTH
MASS AND A MOON. FINALLY 4500 M.A. AGO, THE EARTH IS STABILIZED
AND BECOMES ONE OF THE INTERNAL PLANETS.
