The document discusses the five major latitude regions of the Earth's surface divided based on climate: the North and South Frigid Zones, the North and South Temperate Zones, and the Torrid Zone. These zones were first theorized by ancient Greek philosophers and later refined over time as geographic knowledge improved. Today, the most commonly used climate classification system divides the world into five climate zones based on factors like average temperature and precipitation.
India is home to an extraordinary variety of climatic regions, ranging from tropical in the south to temperate in the Himalayan north, where elevated regions receive sustained winter snowfall. The nation's climate is strongly influenced by the Himalayas and The Thar Desert.Though the Tropic of Cancer—the boundary between the tropics and subtropics—passes through the middle of India, the bulk of the country can be regarded as climatically tropical.

• Earth, along with the other planets, is believed to have been born 4.5 billion years ago as a solidified cloud of dust and gases left over from the creation of the Sun.
• For perhaps 500 million years, the interior of Earth stayed solid and relatively cool, perhaps 2,000°F.
• The main ingredients were iron and silicates, with small amounts of other elements, some of them radioactive.
• As millions of years passed, energy released by radioactive decay—mostly of uranium, thorium, and potassium—gradually heated Earth, melting some of its constituents.
• The iron melted before the silicates, and, being heavier, sank toward the center.
• This forced up the silicates that it found there.
• After many years, the iron reached the center, almost 4,000 mi deep, and began to accumulate. No eyes were around at that time to view the turmoil that must have taken place on the face of Earth—gigantic heaves and bubblings on the surface, exploding volcanoes, and flowing lava covering everything in sight.
• Finally, the iron in the center accumulated as the core. Around it, a thin but fairly stable crust of solid rock formed as Earth cooled.
• Depressions in the crust were natural basins in which water, rising from the interior of the planet through volcanoes and fissures, collected to form the oceans. Slowly, Earth acquired its present appearance.

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.
A Strategic Approach: GenAI in EducationPeter 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.

2. Introduction
The five main latitude regions of the Earth's surface
comprise geographical zones, divided by the
major circles of latitude. The differences between
them relate to climate. They are as follows:
3. History
The concept of a geographical
zone was first hypothesized by
the ancient Greek
scholar Parmenides[1] and
lastingly modified
by Aristotle.[2] Both
philosophers theorized the Earth
divided into three types of
climatic zones based on their
distance from the equator.
Like Parmeneides, thinking that
the area near the equator was
too hot for habitation, Aristotle
dubbed the region around the
equator (from 23.5° N to 23.5° S)
the "Torrid Zone." Both
philosophers reasoned the
region from the Arctic Circle to
the pole to be permanently
frozen. This region, thought
uninhabitable, was called the
"Frigid Zone." The only area
believed to be habitable was the
northern "Temperate Zone" (the
southern one not having been
discovered), lying between the
As knowledge of the Earth's
geography improved, a
second "Temperate Zone"
was discovered south of the
equator, and a second "Frigid
Zone" was discovered
around the Antarctic.
Although Aristotle's map was
oversimplified, the general
idea was correct. Today, the
most commonly used climate
map is the Köppen climate
classification, developed by
Russian climatologist of
German descent and amateur
botanist Wladimir
Köppen (1846–1940), which
divides the world into five
major climate regions, based
on average annual
precipitation, average
monthly precipitation, and
average monthly
4. The North frigid zone, between the Arctic Circle 66.5° N
and the North Pole 90° N. Covers 4.12% of Earth's
surface.
The North temperate zone, between the Tropic of
Cancer 23.5° N and the Arctic Circle 66.5° N. Covers
25.99% of Earth's surface.
The Torrid zone, between the Tropic of Cancer 23.5° N
and the Tropic of Capricorn 23.5° S. Covers 39.78% of
Earth's surface.
The South temperate zone, between the Tropic of
Capricorn 23.5° S and the Antarctic Circle 66.5° S.
Covers 25.99% of Earth's surface.
The South frigid zone, from Antarctic Circle 66.5° S and
the South Pole 90° S. Covers 4.12% of Earth's surface.
5. On the basis of
latitudinal extent, the
globe is divided into
three broad heat
zones
6. Torrid Zone
The Torrid is also known as
the Tropics. The zone is bounded on
the north by the Tropic of Cancer and
on the south by the Tropic of
Capricorn; these latitudes mark the
northern and southern extremes in
which the sun seasonally passes
directly overhead. This happens
annually, but in the region between, the
sun passes overhead twice a year.
In the Northern Hemisphere, in the
sun's apparent northward migration
after the March equinox, it passes
overhead once, then after the June
solstice, at which time it reaches
the Tropic of Cancer, it passes over
again on its apparent southward
journey. After the September equinox
the sun passes into the Southern
Hemisphere. It then passes similarly
over the southern tropical regions until
it reaches the Tropic of Capricorn at
the December solstice, and back again
as it returns northwards to the Equator.
7. Temperate Zones
In the two Temperate Zones,
consisting of the tepid latitudes,
the Sun is never directly
overhead, and the climate is
mild, generally ranging from
warm to cool. The four annual
seasons, spring, summer, autum
n and winter, occur in these
areas. The North Temperate
Zone includes Europe, Northern
Asia, and North and Central
America. The South Temperate
Zone includes
Southern Australasia,
southern South America,
and Southern Africa.
8. The two Frigid Zones, or polar
regions, experience the midnight
sun and the polar night for part
of the year - at the edge of the
zone there is one day at the
winter solstice when the Sun is
invisible, and one day at the
summer solstice when the sun
remains above the horizon for 24
hours. In the center of the zone
(the pole) the day is one year
long with six months of daylight
and six months of night. The
Frigid Zones are the coldest
regions of Earth and are
generally covered in ice and
snow.
