This document discusses how the Earth's continents have moved over millions of years due to the movement of tectonic plates. The Earth originally had one supercontinent called Pangaea, but it broke apart as the plates drifted apart slowly over time. There are two types of crust - oceanic and continental. Oceanic crust is thinner and heavier than continental crust. When plates collide at convergent boundaries, the heavier oceanic crust sinks beneath the lighter continental crust, forming volcanoes and trenches. When plates move apart at divergent boundaries, mid-ocean ridges are formed.
This is the summary on gateway 1 on plate tectonic. It discusses about the following:
1) Characteristics of the different structure of the earth.
2) The mechanism leading to plate movement
3) Landforms associated to the different plate movement.
8th Grade Integrated Science chapter 14 lesson 3 on the theory of plate tectonics. This lesson covers plate boundaries and the effects of the movement. It includes pictures and definitions of divergent, convergent, transform, collision, and subduction boundaries. There is an explanation of the lithosphere and the asthenosphere including convection currents. This also introduces forces causing plate motion such as basal drag, ridge push, and slab pull.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
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.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

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”.
6. Driftin’ . . .
The slow movement of the continents is called
continental drift!
The idea of continental drift is that, gradually and
over millions of years, the continents are moving
around the surface of the Earth.
Millions of years from now, the Earth will appear
differently because the continents will be in
different places!
8. • The crust is not one large sheet
• The crust is made up of many different pieces,
or PLATES, tectonic plates
9. There are TWO different types of crust.
– Continental Crust
• Crust UNDER the continents
• Thicker than the crust under the ocean
– Ocean Crust
• Crust UNDER the ocean
• Thinner than the crust under the continents
• Heavier than continental crust
The Crust
13. Tectonic Plates
• Sometimes, plates PUSH together
• Sometimes, plates PULL APART
• Sometimes, plates SLIDE PAST each other
• Boundaries are where two plates meet
15. Which is heavier- continental plates or plates
under the ocean?
Plates under the ocean!
So, what do you think will happen if a
continental plate and an oceanic plate collide?
Let’s Review
16. Let’s Review
• The oceanic plate will SINK because it is
heavier!
VOLCANOES AND TRENCHES
WILL FORM!
17. Where plates collide you can get:
Mountains
Volcanoes
Earthquakes
Trenches
Tectonic Plates
26. What happens . . .
• . . . When those two tectonic plates slide past
each other??
• They are pushing and pushing . . . Pressure is
building and building . . . .until finally . . . .
BOOM!
• The pressure releases, the plates slide . . . And
you get an EARTHQUAKE!!!!
