Differences of Types of Rocks
Rocks are found everywhere in the Earth surface or beneath land surface. There are three types of rocks the sedimentary, metamorphic, and igneous rocks. These rocks undergo rock cycle. During weathering and erosion these rocks on the earth surface are constantly being broken down and by wind and water.
Sedimentary rocks are formed sediment that is deposited over time, usually as layers at the bottom of lakes and oceans these sediments are the minerals, small pieces of plant and other organic matter, pre-existing rocks or pieces of remains of living organism that accumulate in Earth Surface. These sediments are compressed over a long period of time before they combine into solid layers of rocks. Sedimentary rocks cover most of the rocky Earth surface and less amount of the Earth’s crust. When these rocks are exposed to extreme heat caused by magma or by the intense collisions and friction of tectonic plates which lead to changes in their mineralogy and texture of the rock the Metamorphic rock is formed. Those rocks that are found beneath the Earth surface melts and become magma when a volcano erupts, magma flows out of it. (When magma is on the earth’s surface, it is called lava.) As the lava cools it hardens and becomes igneous rock. As soon as new igneous rock is formed, the processes of weathering and erosion begin, starting the whole cycle over again! Sedimentary structures include features like bedding, ripple marks, fossil tracks and trails, and mud cracks. Sandstone, rock salt and limestone are sedimentary rocks.
Metamorphic textures are salty, schistose, gneissose, granoblastic and Horn felsic. Anthracite and Marble are metamorphic rocks.
Igneous rocks usually hence no layering made up of two or more minerals and they are either glassy or coarse in appearance. Basalt, granite, pumice, obsidian are examples of igneous rocks.

Solution
Minerals-Montmorillonite
Minerals-Kaolinite
The main difference between Igneous, Sedimentary and Metamorphic rocks, is the way that they
are formed, and their various textures.
Igneous Rocks
Igneous rocks are formed when magma (or molten rocks) cool down, and become solid. High
temperatures inside the crust of the Earth cause rocks to melt, and this substance is known as
magma. Magma is the molten material that erupts during a volcano. This substance cools down
slowly, and causes mineralization to take place. Gradually, the size of the minerals increase until
they are large enough to be visible to the naked eye. Igneous rocks are mostly formed beneath
the Earth’s surface.
The texture of Igneous rocks can be referred to as Phaneritic, Aphaneritic, Glassy (or vitreous),
Pyroclastic or Pegmatitic. Examples of Igneous Rocks include granite, basalt and diorite.
Sedimentary Rocks
Sedimentary rocks are usually formed by sedimentation of the Earth’s material, and this
normally occurs inside water bodies. The Earth’s material is constantly exposed to erosion and
weathering, and the resulting accumulated loose particles eventually settle, and form
Sedimentary rocks. Therefore, one can say, that these types of rocks are formed slowly from the
sediments, dust and dirt of other rocks. Erosion takes place due to wind and water. After
thousands of years, the eroded pieces of sand and rock settle, and become compacted to form a
rock of their own.
Sedimentary rocks range from small clay-size rocks to huge boulder-size rocks. The textures of
Sedimentary rocks are mainly dependent on the parameters of the clast, or the fragments of the
original rock. These parameters can be of various types, such as surface texture, round, spherical
or in the form of grain. The most common type of Sedimentary rock is the Conglomerate, which
is caused by the accumulation of small pebbles and cobbles. Other types include shale, sandstone
and limestone, which is formed from clastic rocks and the deposition of fossils and minerals.
Metamorphic Rocks
Metamorphic rocks are the result of the transformation of other rocks. Rocks that are subjected to
intense heat and pressure change their original shape and form, and become Metamorphic rocks.
This change in shape is referred to as metamorphism. These rocks are commonly formed by the
partial melting of minerals, and re-crystallization. Gneiss is a commonly found Metamorphic
rock, and it is formed by high pressure, and the partial melting of the minerals contained in the
original rock.
Metamorphic rocks have textures like slaty, schistose, gneissose, granoblastic or hornfelsic.

Rocks on Earth can be classified into three categories based.pdfadaacollections
Rocks on Earth can be classified into three categories based on the way they were formed.
Igneous rocks are formed through volcanic action. Sedimentary recks are formed by deposition.
Metamorphic rocks are formed when existing rocks undergo a change due to extreme heat and
pressure. Rocks that have a volcanic origin are classifed as igneous and form when magma or lwa
cook and hardens. As the magma or lava cook; crystals begin to form. The size of the crystals
depends upon how fast the magma or lawa cools. If magma cools quickly, small crystals form and
can be observed on the rock surface, such as in basalt, for example. Lava can cool so quickly that
crystals do nothave time to form at all, such as with obsidian. If mogma cools slowly. larger
crystals form and can easily be seen on the surface of rock specimens. A common example of
igneous rock that exhibits large erystal formation is granite. When Earth's materials are deposited
in layers and pressed together over time, sedimentary rocks form. The formation of sedimentary
rock begins with the deposition of sediments. As layers are added, the oldest or lower layers that
were deposited first experience increased pressure. The sediments and the spaces between then
are crushed together in a process cal ied conpaction. During the cementation process, the
sediments are bound together when a solution fills in around the particles like glue. If the
rediments deposited are sand particles, such as in a beach environment, sandstone forms. If the
sediments are fine sit or clay-sited particles, commonly cal ed'mud;' such as those found in basins
worldwide, shaie forms, thestone typically forms from shells and other sediments deposited in
ocean environments. A quiet and undistubed ewironnent will sometimes lead to fossit formation

changes into another due to exposure to heat and pressure ofter cansed by morement of material
deep beneath Carthis surface. This change to rock appearance and cemposition takes an
entrenelylong tine. Metamorphle rocks are often characterized by wavy layers of mineral orytals or
by the presence of unusual mincrals. Any rock can become a metamorphic rock. For example, the
sedimentary rock ahule forms from layers of deposited sitt. When exposed to high pressure due to
scologic processes. the metamorphic rock slate forms. The sedimentary rock sandstone changes
to cuataite when exposed to extreme heat and pressure beneath Eath's surface. Another example
of a metamorphic rock is mable. which forms when limestone is exposed to extreme temperatures
or prescure. Igneous basalt changes to schikt in the metanorphic process. The interesting. thing
about the motamorplic nrocess is that any rock-igneous, metamorphic, or seclinentary-will change
and form now metamorphic rock given enough time, heat, andor pressure. The rock cycle
llustrates how rocks move on and under Earth's crust and change from one typ.

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.

Earth and Life Science_Differences of Types of Rocks.docx
1. Differences of Types of Rocks
Rocks are found everywhere in the Earth surface or beneath land surface.
There are three types of rocks the sedimentary, metamorphic, and igneous rocks.
These rocks undergo rock cycle. During weathering and erosion these rocks on the
earth surface are constantly being broken down and by wind and water.
Sedimentary rocks are formed sediment that is deposited over time, usually
as layers at the bottom of lakes and oceans these sediments are the minerals, small
pieces of plant and other organic matter, pre-existing rocks or pieces of remains of
living organism that accumulate in Earth Surface. These sediments are compressed
over a long period of time before they combine into solid layers of rocks.
Sedimentary rocks cover most of the rocky Earth surface and less amount of the
Earth’s crust. When these rocks are exposed to extreme heat caused by magma or by
the intense collisions and friction of tectonic plates which lead to changes in their
mineralogy and texture of the rock the Metamorphic rock is formed. Those rocks
that are found beneath the Earth surface melts and become magma when a volcano
erupts, magma flows out of it. (When magma is on the earth’s surface, it is called
lava.) As the lava cools it hardens and becomes igneous rock. As soon as new
igneous rock is formed, the processes of weathering and erosion begin, starting the
whole cycle over again! Sedimentary structures include features like bedding, ripple
marks, fossil tracks and trails, and mud cracks. Sandstone, rock salt and limestone
are sedimentary rocks.
Metamorphic textures are salty, schistose, gneissose, granoblastic and Horn
felsic. Anthracite and Marble are metamorphic rocks.
Igneous rocks usually hence no layering made up oftwo or more minerals and
they are either glassy or coarsein appearance. Basalt, granite, pumice, obsidian are
examples of igneous rocks
