Earth as a system is composed of numerous interacting parts or subsystem. Earth system science attempts to integrate the knowledge from traditional sciences, geology, atmospheric science, chemistry, biology and so on. Earth is just a small part of larger system known as the solar system.
Earth system has nearly endless array of subsystems in which matter is recycled over and over again.
The reason for the occurrence of such a huge mass of water on the globe, is still a myth and reality. The reason goes back to the Origin of Earth itself. The exact mode of origin is not precisely known. Scientists assume, both Primary and secondary sources would have given rise to all both air and water on the earth. Two possible sources as internal source (or) external source have been proposed so far. Some of them are attributed towards the theories of origin of the earth.

An introduction to the 4 spheres that make up the interconnected global systems of the earth: the lithosphere, the atmosphere, the hydrosphere and the biosphere.
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.

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.

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.

3. The Atmosphere
The Earth is surrounded by a blanket
of air, called the atmosphere.
• The atmosphere consists of four
layers (the troposphere, the
stratosphere, the mesosphere, and
the thermosphere).
• The atmosphere reaches over 350
miles up from the surface of the
Earth.
• The atmosphere is primarily
composed of nitrogen (about 78%)
and oxygen (about 21%).
4. The Biosphere
The biosphere is the “life zone” of the Earth, and
includes all living organisms (including humans), and all
organic matter that has not yet decomposed.
•Energy and nutrients, like carbon, are transferred
from one level of the food chain to the next.
5. Hydrosphere
The hydrosphere contains all the water
found on our planet.
• Surface Water: Includes the ocean as well
as water from lakes, rivers and creeks.
• Ground Water: Includes water trapped in
the soil and groundwater.
• Atmosphere: water vapor.
• Frozen water: Includes ice caps and
glaciers. Specifically called the cryosphere.
• Only about 3% of the water on Earth is
“fresh” water, and about 70% of the fresh
water is frozen in the form of glacial ice.
(0.9% in liquid form)
6. Geosphere
The geosphere is the solid
part of the earth, from the
core to the surface.
• Includes volcanoes, rocks,
minerals, coal, oil etc.
•Mineral resources are mined
from the geosphere.
7. Earth System
Earth System sci.
is the study of how the
four spheres of the Earth
system interact
continually, each
affecting the others.
8. System Interactions
Volcanoes (geosphere) erupt,
sending ash and gases into the
air (atmosphere) and sending
lava and ash down onto
surrounding forests (biosphere)
and human habitations
(biosphere).
Geosphere
Atmosphere Biosphere
9. System Interactions
Hurricanes (atmosphere) sweep
across the ocean (hydrosphere)
and onto the land (geosphere),
damaging the dwellings of people
(biosphere) who live along the
coast.
Atmosphere
Hydrosphere
Geosphere
Biosphere
10. System Interactions
Earthquakes (geosphere) can damage
buildings which may kill people (biosphere),
as well as cause fires which release gases
into the air (atmosphere). Earthquakes in
the ocean may cause a tsunami
(hydrosphere) which can eventually hit land
and kill both animals and people
(biosphere).

11. Questions
1. Name the four main earth systems.
2. Which branch of science studies the
interactions between these earth systems?
3. A forest fire would effect which earth
systems?
Atmosphere, Biosphere, Hydrosphere and
Geosphere
a scientist that studies global warming.
All four: Fires (Biosphere) will destroy plant and animal life
while releasing smoke and other contaminants into the
atmosphere, hydrosphere and geosphere.
