Warm air rises and leaves behind areas of low pressure, while cold air sinks and creates high pressure. The uneven heating of the Earth's surface causes wind as air moves from high to low pressure areas. Humidity refers to the amount of water vapor in the air, which depends on temperature - cold air can hold less vapor than warm air. Clouds form through condensation of water vapor on particles in the air, and different cloud types like cumulus and cirrus form at varying altitudes. Air masses develop characteristic properties based on the surface they pass over.
this ppt is all on atmospheric pressure mainly focused on pearson class 7 social text book hope you understand each and every point to remind you this is not based on NCERT textbook
hope you like it! there is a lot about water vapour and mist

Air Pollution, Asthma, Triggers & Health - Research and Remediation StrategiesSean McCormick
This content was created to help provide health care practitioners with more detailed information about air pollution, it's impact on health, and low-no-cost strategies for reducing exposure to asthma triggers.
The intention of this resource is to provide you with enough information to produce a high quality reports and literature reviews.
You may need to produce several small reports during the course of your undergraduate study as part of group coursework assignments. This guide along with other provide support.
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
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.

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.
3. Air Pressure
Warm air= expanding or rising air= leaves
behind L pressure
Cold Air=sinking air= leaves an area of H
pressure
4. W in d M o v e -
me n t
Uneven heating of the
earth’s surface causes
some areas to be
warmer than others.
As we know, warm al-
ways follows cold to
share it’s warmth-
when this happens in
the atmosphere, wind
5. What causes winds?
A wind is a horizontal Winds are measured
movement of air from by direction and speed
a area of high pres-
sure to an area of low The anemometer is
pressure the tool we use to
It is this difference in measure this
pressure that makes Wind chill=↑ cooling
the air move=wind
the wind causes
6. Water in the Atmosphere: Hu-
midity
Humidity: measure of the amount of water vapor stuck
between molecules in the air. The air’s ability to hold
water depends on the air temp
The hotter the air, the more water the air can hold
Cold air: molecules move slower so droplets of water
can start to stick together=condensation
Relative humidity: the amount of water vapor(%) com-
pared to the amount the air can hold- tool used is a
psychrometer.
100%=air is saturated
7. Cloud Formation
Clouds form when water vapor condens-
es on dust, salt particles in the air
The temperature in which condensation
begins is called the dew point
8. TYPES OF CLOUDS
Cirrus Clouds: wispy, feathery clouds
Form only at high levels, therefore are made of i
11. Types of Clouds
Stratus Clouds: clouds that form in flat
layers- cover all or most of the sky and
are low level clouds
12. Air Masses
Air masses are masses of air that have
the same characteristics of the surface
over which it develops
Pressure Systems
descending (going down)=H pressure
ascending (going up)=L pressure
