The document discusses the four main subsystems that make up the Earth: the atmosphere, geosphere, hydrosphere, and biosphere. It provides details on each subsystem, including the composition and layers of the atmosphere. The subsystems interact with each other through flows of matter and energy. For example, the atmosphere provides heat and energy to the geosphere while the biosphere receives gases, heat, sunlight and water from the other subsystems. This dynamic interaction between the subsystems creates a habitable environment for life on Earth.
Earth system refers to Earth’s interacting physical, chemical, and biological processes.
The system consists of the land, oceans, atmosphere and poles.
It includes the planet’s natural cycles – the carbon, water, nitrogen, phosphorus, Sulphur and other cycles – and deep Earth processes.

Elements of the Physical Environment
The environment can basically described to be everything that surrounds man, interacts with man and influences the way he exists. The elements therefore can be put to four different categories: the atmosphere which contains the air, gases, climate and water, the hydrosphere that includes water in oceans, seas, rivers and lakes, the lithosphere that describes things on the earth’s surface like rocks, soil and landforms and finally the biosphere that contains life or living things like the flora – plants and fauna – animals. Environment means the surroundings. Land, water, air, plants, animals, solid wastes and other things that are surrounding us constitute our environment. Man and environment are closely intertwined with each other, to maintain a balance or equilibrium in nature.
The Earth's atmosphere is a thin layer of gases that surrounds the Earth. It made up of 78% nitrogen, 21% oxygen, 0.9% argon, 0.03% carbon dioxide, and very minimal amounts of other gases. This thin gaseous layer insulates the Earth from extreme temperatures; it keeps heat inside the atmosphere and it also blocks the Earth from much of the Sun's incoming ultraviolet radiation. It’s approximated to be about 480 km thick, but most of the atmosphere (about 80%) is within 16 km of the surface of the Earth. There is no exact place where the atmosphere ends; it just gets thinner and thinner, until it merges with outer space. The atmospheric air pressure at sea level, is about equals 760 mm (29.92 inches) of mercury, 14.70 pounds per square inch the air pressure decreases. At an altitude of 10,000 feet, the air pressure is 10 pound per square inch and there is less oxygen to breathe. The atmosphere is made up of layers namely: the thermosphere which includes the exosphere and part of the ionosphere, the exosphere which is the outermost layer of the Earth's atmosphere. The exosphere goes from about 640 km high to about 1,280 km, the ionosphere that starts at about 70-80 km high and continues for hundreds of kilometers like 640 km. It contains many ions and free electrons. The ions are created when sunlight hits atoms and tears off some electrons. Auroras occur in the ionosphere. Others include the mesosphere characterized by decreasing temperatures as you rise, the stratosphere characterized by slight temperature increase with altitude, the tropopause which sits between the stratosphere and the troposphere and finally the troposphere which is the lowest region in the earth’s atmosphere.
A hydrosphere is the total amount of water on a planet. The hydrosphere includes water that is on the surface of the planet, underground, and in the air. A planet's hydrosphere can be liquid, vapor, or ice. On Earth, liquid water exists on the surface in the form of oceans, lakes and rivers. It also exists below ground—as groundwater, in wells and aquifers. Water vapor is most visible as clouds and fog. The frozen part ...

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.

C D
BIOSPHERE HYDROSPHERE
GEOSPHERE ATHMOSPHERE
19. Subsystems of the Earth
1. ATMOSPHERE
Composed of 78% nitrogen (N), 21% oxygen
(O2), 1% other gases like argon, carbon
dioxide, carbon monoxide, ozone, and other inert
gases.
Supports life
Regulates climate
Acts as both a blanket and a filter
20. Layers of the Athmosphere
Mnemonic device
for the layers of
the atmosphere:
That Snake Mus
t Think: I’m Evil
21. a. Troposphere
The troposphere is by far the wettest
layer of the atmosphere (all of the other
layers contain very little moisture).
is the lowest layer of Earth's
atmosphere and it is the closest layer to
Earth’s surface. It is the layer we live in.
Where all the weather occurs.
22. b. Stratosphere
It is the second layer of the atmosphere
as you go upward.
is very dry air and contains little water
vapor.
is where you'll find the very important
ozone layer.
Jets fly here.
23. c. Mesosphere
The third and coldest layer of
Earth’s atmosphere, reaching
about 130 degrees below zero.
Is also where most meteors, or
space rocks and metal, burn up
before they crash the ground.
24. d. Thermosphere
The fourth layer of the
Earths atmosphere that
absorbs the sun’s
radiation, making it very
hot.
It is also where satellites
25. e. Ionosphere
Is a very active part of the
atmosphere, and it grows and shrinks
depending on the energy it absorbs
from the sun.
Its name comes from the fact that
gases in these layers are excited by
solar radiation to form “ions” which
have an electrical charge.
26. f. Exosphere
Is the very edge of our atmosphere.
This layer is the outermost layer of
our atmosphere. “Exo” means outside.
This layer separates the rest of the
atmosphere from outer space.
Is really, really big- to get to outer
space you have to be really far from
Earth.
27. 2. GEOSPHERE
Subsystems of the Earth
comes from the Greek word
geos meaning ground.
Refers to the solid Earth,
consisting of the entire planet
from the center of the core to
the outer crust.
28. It is the solid, outermost layer of the
Earth that is composed of rocks.
Beneath the crust, composed
of molten rocks
liquefied part
of the Earth
solid, central
part of the
Earth.
29. 3. HYDROSPHERE
Subsystems of the Earth
“Hydro” is a Greek word which means water.
Is the totality of Earth’s water, including the
permanently frozen parts called cryosphere.
About 71% of the Earth is covered with liquid water
(hydrosphere) and much of it is in the form of ocean
water
Only 3% of Earth's water is fresh: two-thirds are in
the form of ice, and the remaining one-third is
present in streams, lakes, and groundwater.
30. 4. BIOSPHERE
Subsystems of the Earth
Comes from the Greek word “bios” meaning
LIFE.
Includes all life forms and even organic matter
that has not yet decomposed.
Life on Earth exists within a zone where
interactions among the four subsystems occur to
create a habitable environment.
Sometimes called as the large ecosystem.
31. How does matter and energy flow across the four
subsystems of Earth
The
atmosphere
provides the
geosphere with
heat and energy
needed for rock
breakdown and
erosion.
The biosphere
receives gases, heat,
and sunlight
(energy)from the
atmosphere. It
receives water from
the hydrosphere and
a living medium from
the geosphere.
32. Carbon cycle
In this cycle, carbon can be stored in the
biosphere (within plants), atmosphere (as
carbon dioxide), hydrosphere (dissolve as CO2 in
the oceans), and geosphere (as coal and oil
deposits). The right amount of CO2 in the
atmosphere helps regulate a temperature range
that is conducive to life. Too much CO2 may
lead to warmer temperature, may lead to global
warming and subsequent climate change.
