The document discusses the Earth's surface. 3/4 of the Earth is covered in water, with oceans being the largest bodies. The remaining 1/4 is land, consisting of different landforms like mountains, plains, and plateaus. The Earth's surface is constantly changing through processes like volcanoes and earthquakes. Volcanoes can create new mountains and islands but also destroy existing landforms. Earthquakes are caused by movements of tectonic plates and faults in the Earth's crust.

Earth is the third planet from the Sun and the only object in the Universe known to harbor life. According to radiometric dating and other sources of evidence, Earth formed over 4 billion years ago.[24][25][26] Earth's gravity interacts with other objects in space, especially the Sun and the Moon, Earth's only natural satellite. Earth revolves around the Sun in 365.26 days, a period known as an Earth year. During this time, Earth rotates about its axis about 366.26 times.[n 5]
Earth's axis of rotation is tilted, producing seasonal variations on the planet's surface.[27] The gravitational interaction between the Earth and Moon causes ocean tides, stabilizes the Earth's orientation on its axis, and gradually slows its rotation.[28] Earth is the densest planet in the Solar System and the largest of the four terrestrial planets.
Earth's lithosphere is divided into several rigid tectonic plates that migrate across the surface over periods of many millions of years. About 71% of Earth's surface is covered with water, mostly by oceans.[29] The remaining 29% is land consisting of continents and islands that together have many lakes, rivers and other sources of water that contribute to the hydrosphere. The majority of Earth's polar regions are covered in ice, including the Antarctic ice sheet and the sea ice of the Arctic ice pack. Earth's interior remains active with a solid iron inner core, a liquid outer core that generates the Earth's magnetic field, and a convecting mantle that drives plate tectonics.
Within the first billion years of Earth's history, life appeared in the oceans and began to affect the Earth's atmosphere and surface, leading to the proliferation of aerobic and anaerobic organisms. Some geological evidence indicates that life may have arisen as much as 4.1 billion years ago. Since then, the combination of Earth's distance from the Sun, physical properties, and geological history have allowed life to evolve and thrive.[30][31] In the history of the Earth, biodiversity has gone through long periods of expansion, occasionally punctuated by mass extinction events. Over 99% of all species[32] that ever lived on Earth are extinct.[33][34] Estimates of the number of species on Earth today vary widely;[35][36][37] most species have not been described.[38] Over 7.4 billion humans live on Earth and depend on its biosphere and natural resources for their survival. Humans have developed diverse societies and cultures; politically, the world has about 200 sovereign states.
This document looks at volcanoes in detail. It starts with the definition of volcanoes and the labeling of the different parts of a volcano. Then it looks at the different extrusive and intrusive volcanic features. It also looks at the positive and negative effects of volcanic activity
A volcano is a mountain that opens downward to a pool of molten rock below the surface of the earth. When pressure builds up, eruptions occur. Gases and rock shoot up through the opening and spill over or fill the air with lava fragments. Eruptions can cause lateral blasts, lava flows, hot ash flows, mudslides, avalanches, falling ash and floods. Volcano eruptions have been known to knock down entire forests. An erupting volcano can trigger tsunamis, flash floods, earthquakes, mudflows and rockfalls.

A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface.

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.

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.
1. What is the Earth’s Surface
Like?
Would you ever live in a cave on the side of a tall cliff?
Imagine looking out your door and finding that you’re high
above the ground. YIKES!
But early people did build homes in high rocks.
2. If you look at a picture of the earth taken
from space, what do you see?
3. Water!
¾ of the earth is covered by water. The oceans are the
largest bodies of water. Rivers carry water from the land
to the oceans.
4. What About the Other ¼?
Landforms!
-Different shapes of land
-Includes: mountains, plains, and
plateaus
8. Why Are There Different Landforms?
The surface of the earth is ALWAYS
changing.
Some of these changes happen slowly
over time.
Other changes happen quickly.
9. Volcanoes
A mountain formed by hardened lava with an opening
through which lava, ashes, rocks, and other materials
may come out.

10. Active Volcano
Magma forms when the heat and pressure melt rocks
inside the earth. Volcanoes form when heat and gases
cause pressure to build up under the surface of the
earth. When enough pressure builds up, the magma
forces it way through weak spots, called vents. Then
the magma breaks through the surface. When the
magma cools, it hardens, which forms the mountain
called a volcano.
11. Violent Eruption
Sometimes a volcano erupts with such force that part of
the volcanic mountain may be blown to pieces.
12. Dormant Volcano
A volcano that is “sleeping.” It hasn’t erupted in recent
times. Inside, the mountain may be building up
pressure that will some day be released.
13. Effects of Volcanoes
Volcanoes create new mountains
Volcano eruptions can destroy mountains
Volcanoes can create new islands
14. Earthquakes
The shaking of the ground caused by rock movement
along a fault
Fault: a crack in he earth’s cruse along which rocks
move.
15. Tectonic Plates
Large sections of rock that make up the earth’s crust.
They are always moving.
This movement causes cracks in the crust, which are called faults.
When the rocks along a fault move, the ground shakes.
Most of these earthquakes are not felt by people; however, some
earthquakes can cause a lot of damage.
16. Let’s Review!
List three types of landforms found on the earth.
Plains
Mountains
plateaus
17. How do volcanoes change the
surface of the earth?
Volcanoes can create new mountains and new islands.
They can also destroy parts of mountains.
18. What causes earthquakes?
Earthquakes are cased when the rocks along a fault
move and cause the ground to shake.
