The PPT is about radioaactve decay it's ionising and peneterating power and about madam curie and her biography
madam curies does not actually discovered radioactivity but due to her great job in this field it is said that she discovered radioactivity
Continental rifts are regions of extensional deformation where the entire thickness of the lithosphere has deformed under the influence of deviatoric tension.
Rifts represent the initial stage of continental break-up where extension may lead to lithospheric rupture and the formation of a new ocean basin.

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”.

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 wind?
The perceptible natural movement of the Air especially in the form of
current Air blowing from a particular direction
•The words derived from “Aeolus” the Greek which mean God of wind
•Wind is moving air and is caused by differences in air pressure within our
atmosphere air under high pressure moves toward areas of low pressure. The
greater difference in pressure the faster the air flow
WIND EROSION AND DEPOSITION
2. The process in which sediment is picked up and moved from one place to
another place.
•what are the forces which cause erosion?
•The force of gravity, running water,glaciers,waves and wind
•Wind is actually the weakest of erosion.water ice and waves are much
stronger agent but wind can be powerful shaping force if there are no plants
to hold the soil in place.
WHAT IS EROSION?
3. PROCESSOF EROSION
1. Deflation
2. Abrasion
1. Deflation. Wind removes the top layer of sediment and leaves behind the larger, heavier
pieces of rock.
2. Abrasion is the mechanical scraping of a rock surface by friction between rocks and
moving particles during transport by wind and other erosional agents.
4. Transportation
1. Saltation is the movement of sand or other sediment by short jump and bounce
2. Attrition is the process of reducing something's strength or effectiveness
through sustained attack or pressure.
3. Suspension wind smaller particle moving by suspension
4. Surface Creeps
5. 1. Deflation hollow which is wind create depression on the surface of earth and
hollow it is also called blow out. A surface depression or hollow commonly
found in arid and semi arid region caused by wind
EROSIONAL LANDFORM BY WIND
6. Desert pavement.
Deflation is removal of fine particles by wind. The resulting hole is a blowout. If
coarser material is left behind, it can form (desert) pavement. Deflation can remove
a significant amount of sand and silt
A desert pavement, also called reg (in the western Sahara), serir (eastern Sahara),
gibber (in Australia), or saï (central Asia)
7. Desert varnishing.
Jun 22, 2013 - A strange red, brown and black coating covers many desert rocks
and is known as desert varnish
Shining of any surface due to colliding of pebbles and erosion of less material
8. Ventifact or Driekants
Polish of surface any pebbles with two or more side as
called ventifact or driekants
Ventifacts,
Antarctica
9. Yardang.
Yardangs are formed by wind erosion, typically of an originally flat surface formed
from areas of harder and softer material. The soft material is eroded and removed by
the wind, and the harder material remains. The resulting pattern of yardangs.it is a
sequence of vertical faros.
10. Zeugen.
It is a sequence of horizontal faros.
ZEUGENS are also formed by wind abrasion where a surface layer of hard rock is
underlain by a layer of soft rock into a ridge and furrow landscape. The ridges are
called zeugens which may be as high as 100 feet. Ultimately the are undercut and
gradually worn away. Zeugen resistance rock forms block like ridges called zeugen.
11. Mesas and butte.
A mesa is considered both a geography and geology term. The mesa is an isolated,
high plateau with a flat top and steep sides. It is commonly found in dry regions of
the western and southwestern United States.
the Spanish word, mesa, meaning table.
A butte is also considered to be both a geographical and geological term. This
formation looks like a mountain or a hill that is flat topped and isolated from the
surrounding area
12. Mushroom and pedestal rock.
A mushroom rock, also called rock pedestal or a pedestal rock, is a naturally
occurring rock whose shape, as its name implies, strikingly resembles a mushroom.
14. Monolith and Honey comb.
This word comes from the Greek, and it literally means “single stone”
The term “monolith” is used in a number of ways. Basically, a monolith is a really
big stone, and there are both natural monoliths, like Uluru in Australia, and
artificial monoliths, such as the standing stones at Stonehenge.
Which is small hole in the rock it is called honey comb.
15. Two category.
1. Small scale
2. Large scale
I. sand drift or sand sheet.
Sand sheets are flat, gently undulating plots of sand
surfaced by grains that may be too large for saltation. They
form approximately 40 percent of Aeolian depositional
surfaces. Sand sheets exist where grain size is too large, or
wind velocities too low, for dunes to form.
DEPOSITIONAL FEATURE BY WIND
16. Sand ripple.
one of a series of small ridges produced by wind
Sand fall.
formation of sand shadow were wind sweep sand over a drifition such deposit
is known as sand fall
17. Large scale.
1. Dunes
2. Active Dunes
3. Passive Dunes
On The Basis of Shape
1. Crescent
2. Longitudinal
3. Star Shaped
4. Parabolic
5. Transvers Sand Dunes
6. Whale Back
7. Undulation
