The document provides information about the Moon:
- The Moon has 1/80 the mass and 1/4 the diameter of Earth. Its orbit is nearly circular with a mean distance of 384,000 km from Earth.
- The Moon causes Earth's tides and the slowing of Earth's rotation over time. The Moon's surface shows impact craters and lacks atmosphere or liquid water.
- Samples returned by Apollo astronauts show the Moon has a similar composition to Earth's mantle but is deficient in iron and volatiles like water, suggesting it formed from mantle material ejected during an ancient giant impact.

Flowing water has the ability to dissolve the soluble mineral substances available on its way. The processes enacted by streams are called as fluvial processes. The word “fluvius” is derived from the latin word meaning “ river”. The world fluvial is used to denote the running water as streams or rivers. Fluvial processes entail the erosion, transportation, and deposition of earth materials by running water. Fluvial processes and fluvial landforms dominate land surfaces the world over, as opposed to the limited effects of glacial, coastal, and wind processes.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Palestine last event orientationfvgnh .pptxRaedMohamed3
An EFL lesson about the current events in Palestine. It is intended to be for intermediate students who wish to increase their listening skills through a short lesson in power point.
1. Mass of the Moon is about 1/80 that of the Earth, and its diameter is about 1/4 that of the Earth. The orbit is very nearly circular (eccentricity ~ 0.05) with a mean separation from the Earth of about 384,000 km, which is about 60 Earth radii. The plane of the orbit is tilted about 5 degrees with respect to the ecliptic plane. The Moon
2. Moon is the primary cause of tides Tides due to the Sun are two times weaker The interior of the Moon and Earth is heated by tides. (Compare to Io!)
3. As the Earth rotates beneath the tidal bulges, it attempts to drag the bulges along with it. A large amount of friction is produced which slows down the Earth's spin. The day has been getting longer and longer by about 0.0016 seconds each century. The Earth’s day was 18 hours long 900 million yr ago Eventually the Earth will keep one face towards Moon. Moon already keeps one face towards Earth – rotational period equals orbital period of 29.5 days.
4. Fig. 17-4b, p.353 Since the synodic rotational period of the Moon is 29.5 days, Lunar day and Lunar night are each about 15 Earth days long. During the Lunar night the temperature drops to around -113 degrees Celsius, while during the Lunar day the temperature reaches 100 degrees Celsius. The temperature changes are very rapid since there is no atmosphere or surface water to store heat.
5. Moon has too weak gravity to keep the atmosphere. That is why it also does not have liquid water. It may have ice though (important for future stations!)
7. Impact Cratering Impact craters on the moon can be seen easily even with small telescopes. Ejecta from the impact can be seen as bright rays originating from young craters
9. History of Impact Cratering Most craters seen on the moon’s (and Mercury’s) surface were formed within the first ~ 1/2 billion years. Rate of impacts due to interplanetary bombardment decreased rapidly after the formation of the solar system.
10. Moon Rocks All moon rocks brought back to Earth are igneous (= solidified lava) No sedimentary rocks => No sign of water ever present on the moon. Different types of moon rocks: Vesicular (= containing holes from gas bubbles in the lava) basalts, typical of dark rocks found in maria Breccias (= fragments of different types of rock cemented together), also containing anorthosites (= bright, low-density rocks typical of highlands) Older rocks become pitted with small micrometeorite craters
12. Formation of Maria Impacts of heavy meteorites broke the crust and produced large basins that were flooded with lava
13. The Moon's density (3.3 g/cm 3 ) is fairly uniform throughout and is only about 3.3 times the density of water. If it has an iron core, it is less than 800 kilometers in diameter. This is a sharp contrast from planets like Mercury and the Earth that have large iron-nickel cores and overall densities more than 5 times the density of water. The Moon's mantle is made of silicate materials, like the Earth's mantle, and makes up about 90% of the Moon's volume. The temperatures do increase closer to the center and may be high enough to partially liquify the material close to the center. Its lack of a liquid iron-nickel core and slow rotation is why the Moon has no magnetic field. Lunar samples brought back by the Apollo astronauts show that compared to the Earth, the Moon is deficient in iron and nickel and volatiles (elements and compounds that turn into gas at relatively low temperatures) such as water and lead. The Moon is richer in elements and compounds that vaporize at very high temperatures. The Moon's material is like the Earth's mantle material but was heated to very high temperatures so that the volatiles escaped to space. Strange peculiarities in the Moon’s composition
14. Our Moon could have been formed in a giant collision 4.5 billion years ago
15. proposes that a large Mars-sized object hit the Earth and blew mantle material outward which later recoalesced to form the Moon. The Earth had already differentiated by the time of the giant impact so its mantle was already iron-poor. The impact and exposure to space got rid of the volatiles in the ejecta mantle material. Such an impact was rare so is was not likely to have also occurred on the other terrestrial planets. Giant impact theory:
19. The surface conditions are among the harshest in the Solar System. During the long Mercurian day the temperature rises to about 425 degrees Celsius, hot enough to melt lead and hotter than any planet except Venus. Because there is no substantial atmosphere to retain heat, during the equally long nights, the temperature drops quickly to around -180 degrees Celsius, which is among the coldest found in the Solar System. This range of -180 Celsius at night to 425 Celsius in the day is the largest surface temperature variation in the Solar System.
22. Venus - the brightest "star" The goddess of beauty
23.
24. Venus is the second planet from the Sun, with a nearly circular orbit having an average radius of 0.7 A.U. This gives it an orbital period of 225 days. Venus is peculiar in that its rotation is retrograde (in the opposite sense of the Earth and all other planets except Uranus) and because it is very slow: a day on Venus corresponds to 243 Earth days. At present, we have no solid explanation for why this is so. The most plausible theories invoke the collision of two large masses to form Venus in just such a way to cancel most of the rotation for the two masses. Like Mercury, but unlike the other planets, Venus has no moons. UV Radio image
27. Venus is about 95% the size of the Earth and has 82% of the Earth's mass. Like the Earth, Venus has a rocky crust and iron-nickel core. But the similarities stop there. Venus has a thick atmosphere made of 96% carbon dioxide ( CO2 ), 3.5% nitrogen ( N2 ), and 0.5% other gases. At Venus' surface, the air pressure is 91 times the Earth's surface atmospheric pressure. Venus' surface atmospheric pressure is the same as what you would feel if you were 1 kilometer below the ocean surface on the Earth. A human cannot survive at depths greater than just 70 meters below the ocean surface without special diving suits or a submarine. If you want to send someone to Venus, that person would need to be in something like a diving bell. The Venus explorer would also need a very powerful cooling system: the surface temperature is 737 K (= 477° C)! This is hot enough to melt lead and is over twice as hot as it would be if Venus did not have an atmosphere. Why does Venus have such a thick atmosphere and why is it so hot on its surface?
28. The Atmosphere of Venus UV image Extremely inhospitable: 96 % carbon dioxide (CO 2 ) 3.5 % nitrogen (N 2 ) Rest: water (H 2 O), hydrochloric acid (HCl), hydrofluoric acid (HF) 4 thick cloud layers ( surface invisible to us from Earth). Very stable circulation patterns with high-speed winds (up to 240 km/h) Extremely high surface temperature up to 745 K (= 880 o F) Very efficient “greenhouse”! UV image

33. "It will be possible to see cities on Mars, to detect navies in [its] harbors, and the smoke of great manufacturing cities and towns... Is Mars inhabited? There can be little doubt of it ... conditions are all favorable for life, and life, too, of a high order. Is it possible to know this of a certainty? Certainly." Samuel Leland 1895
34. Tales of Canals and Life on Mars Early observers (Schiaparelli, Lowell) believed to see canals on Mars This, together with growth/shrinking of polar cap, sparked imagination and sci-fi tales of life on Mars. We know today: “canals” were optical illusion; do not exist! No evidence of life on Mars.
35. Mars is about half the diameter of the Earth and has 1/10th the Earth's mass. Mars' thin atmosphere (just 1/100th the Earth's) does not trap much heat at all even though it is 95% carbon dioxide ( CO2 ). The other 3% is nitrogen ( N2 ). Because the atmosphere is so thin, the greenhouse effect is insignificant and Mars has rapid cooling between night and day. When night comes the temperature can drop by over 100 K (180° F)! The large temperature differences create strong winds. The strong winds whip up dust and within a few weeks time, they can make dust storms that cover the entire planet for a few months.
36.
37. The Geology of Mars Giant volcanoes Valleys Impact craters Vallis Marineris Reddish deserts of broken rock, probably smashed by meteorite impacts.
38. Volcanism on Mars Volcanoes on Mars are shield volcanoes. Olympus Mons: Highest and largest volcano in the solar system.
39. The Geology of Mars (2) Northern Lowlands: Free of craters; probably re-surfaced a few billion years ago. Southern Highlands: Heavily cratered; probably 2 – 3 billion years old. Possibly once filled with water.
40. Hidden Water on Mars No liquid water on the surface: Would evaporate due to low pressure. But evidence for liquid water in the past: Outflow channels from sudden, massive floods Collapsed structures after withdrawal of sub-surface water Splash craters and valleys resembling meandering river beds Gullies, possibly from debris flows Central channel in a valley suggests long-term flowing water
41. Hidden Water on Mars (2) Gusev Crater and Ma’adim Vallis: Giant lakes might have drained repeatedly through the Ma’adim Vallis into the crater.
