This document provides an overview of geomorphological processes and environments. It begins with defining geomorphology as the scientific study of landforms and the processes that shape them. It then discusses various landform features seen on Earth's surface and how geomorphology seeks to understand the processes behind their formation. The document outlines different agents of geomorphic processes like rivers, wind, glaciers and waves. It categorizes geomorphic processes into terrestrial and extra-terrestrial processes, with terrestrial processes further divided into exogenetic and endogenetic processes. Key exogenetic processes discussed include weathering, erosion, transportation, deposition and mass movement, while endogenetic processes include faulting, folding, volcanism, earthquakes, land

The reason for the occurrence of such a huge mass of water on the globe, is still a myth and reality. The reason goes back to the Origin of Earth itself. The exact mode of origin is not precisely known. Scientists assume, both Primary and secondary sources would have given rise to all both air and water on the earth. Two possible sources as internal source (or) external source have been proposed so far. Some of them are attributed towards the theories of origin of the earth.

Themis: An I/O-Efficient MapReduce (SoCC 2012)Alex Rasmussen
Â
âBig Dataâ computing increasingly utilizes the MapReduce programming model for scalable processing of large data collections. Many MapReduce jobs are I/O-bound, and so minimizing the number of I/O operations is critical to improving their performance. In this work, we present Themis, a MapReduce implementation that reads and writes data records to disk exactly twice, which is the minimum amount possible for data sets that cannot fit in memory. In order to minimize I/O, Themis makes fundamentally different design decisions from previous MapReduce implementations. Themis performs a wide variety of MapReduce jobs â including click log analysis, DNA read sequence alignment, and PageRank â at nearly the speed of TritonSortâs record-setting sort performance [29].
Geology, a word that literally means âstudy of Earthâ. Geology is traditionally divided into two broad areas: physical and historical.
Physical geology examines the materials composing Earth and seeks to understand the many processes that operate beneath and upon its surface. Earth is a dynamic, ever-changing planet. Internal forces create earthquakes, build mountains, and produce volcanic structures. At the surface, external processes break rock apart and sculpt a broad array of landforms. The erosional effects of water, wind, and ice result in a great diversity of landscapes. Because rocks and minerals form in response to Earthâs internal and external processes, their interpretation is basic to an understanding of our planet.
In contrast to physical geology, the aim of historical geology is to understand the origin of Earth and the development of the planet through its-billion-year history.

"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
Â
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.

Micro RNA genes and their likely influence in rice (Oryza sativa L.) dynamic ...Open Access Research Paper
Â
Micro RNAs (miRNAs) are small non-coding RNAs molecules having approximately 18-25 nucleotides, they are present in both plants and animals genomes. MiRNAs have diverse spatial expression patterns and regulate various developmental metabolisms, stress responses and other physiological processes. The dynamic gene expression playing major roles in phenotypic differences in organisms are believed to be controlled by miRNAs. Mutations in regions of regulatory factors, such as miRNA genes or transcription factors (TF) necessitated by dynamic environmental factors or pathogen infections, have tremendous effects on structure and expression of genes. The resultant novel gene products presents potential explanations for constant evolving desirable traits that have long been bred using conventional means, biotechnology or genetic engineering. Rice grain quality, yield, disease tolerance, climate-resilience and palatability properties are not exceptional to miRN Asmutations effects. There are new insights courtesy of high-throughput sequencing and improved proteomic techniques that organismsâ complexity and adaptations are highly contributed by miRNAs containing regulatory networks. This article aims to expound on how rice miRNAs could be driving evolution of traits and highlight the latest miRNA research progress. Moreover, the review accentuates miRNAs grey areas to be addressed and gives recommendations for further studies.

Diabetes is a rapidly and serious health problem in Pakistan. This chronic condition is associated with serious long-term complications, including higher risk of heart disease and stroke. Aggressive treatment of hypertension and hyperlipideamia can result in a substantial reduction in cardiovascular events in patients with diabetes 1. Consequently pharmacist-led diabetes cardiovascular risk (DCVR) clinics have been established in both primary and secondary care sites in NHS Lothian during the past five years. An audit of the pharmaceutical care delivery at the clinics was conducted in order to evaluate practice and to standardize the pharmacistsâ documentation of outcomes. Pharmaceutical care issues (PCI) and patient details were collected both prospectively and retrospectively from three DCVR clinics. The PCI`s were categorized according to a triangularised system consisting of multiple categories. These were âchecksâ, âchangesâ (âchange in drug therapy processâ and âchange in drug therapyâ), âdrug therapy problemsâ and âquality assurance descriptorsâ (âtimer perspectiveâ and âdegree of changeâ). A verified medication assessment tool (MAT) for patients with chronic cardiovascular disease was applied to the patients from one of the clinics. The tool was used to quantify PCI`s and pharmacist actions that were centered on implementing or enforcing clinical guideline standards. A database was developed to be used as an assessment tool and to standardize the documentation of achievement of outcomes. Feedback on the audit of the pharmaceutical care delivery and the database was received from the DCVR clinic pharmacist at a focus group meeting.

UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Â
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.

6. Geomorphology
The word Geomorphology derived from Greek: geo, "earth"; morfĂŠ,
"form"; and logos, "study"; is the scientific study of landforms and the
processes that shape them.
It is a composite science, is the study of landforms including, in recent
times especially, investigations into the processes that cause and alter
the landforms.
Geomorphology is practiced within physical geography, geology,
geodesy, engineering geology, archaeology and geotechnical
engineering.

7. Why Geomorphology?
To understand geomorphological processes of various
environment.
To detect natural and environmental hazards efficiently, e.g.
earthquake, flooding, landslide, tsunami, volcanism etc.
To identify various landform features and landscapes
To identify various landform features from satellite images

10. Geomorphic Process
The process responsible for the formation and alteration of the
earth's surface.
The physical and chemical interactions between the earth's
surface and the natural forces acting upon it to produce
landforms.
The processes are determined by such natural environmental
variables as geology, climate, vegetation and base level, to say
nothing of human interference.

11. Geomorphic Process (ContâŚ)
Definition:
The geomorphic processes are all those physical and
chemical changes which effect a modification of the
earthâs surgical form [W. D. Thornbury (1968): Principles
of Geomorphology, pp. 34].
A process by which the earthâs land forms are changed or
maintained [Jim Gardner (1979): Physical Geology].

20. Types of Geomorphic Processes (ContâŚ)
Endogenetic Processes
Inner geomorphological processes = endogenetic processes
(earthquakes, volcanoes, folding and faulting) create rough
features of the Earth´s relief. e.g. oceanic basins, mountain
ranges, oceanic ridges and trenches, rift valleys, folds, faults
and volcanoes, etc.

21. Basic difference between the two process
Processes that are caused by forces from within the
Earth are endogenous processes.
By contrast, exogenous processes come from forces
on or above the Earth's surface.
Endogenic Processes Exogenic Processes
Originate in the interior of the earth. Originate on the surface of the earth.
Causes sudden or rapid movements Causes slow movements.
Eg: Earthquake, faulting, diastrophism Eg: Erosional and Depositional

ii. Erosion/ Degradation
iii. Transportation
iv. Deposition/Aggradation
v. Mass movement
22
23. Denudation
It means to make the things exposed.
The processes by which the rocks on the earthâs surface are broken
into pieces through the application of external physical forces and
the debris are transported elsewhere is known as denudation.
This denudation work is performed through three processes such as
weathering, erosion and transportation.
Denudation= Weathering + Erosion + Transportation
23
25. Weathering
The weathering is a process by which the rocks on the surface
of the earth is broken mechanically into pieces due to snow or
frost, the variation of temperature and pressure or due to
chemical (dissolution) action on the materials.
Even the rocks are dislodged by the animals. But the rocks
weathered this way, are not transported elsewhere.
25
26. Erosion
Erosion and transportation are accomplished together.
The process by which the rocks of the earthâs crust are eroded
by the river, wind, glacier, ocean currents etc. are transported
elsewhere is known as erosion.
26
27. Degradation
Degradation is the lowering of a bottomland surface through
the process of erosion;
Conceptually it is the opposite of the vertical component of
aggradation and is most frequently applied to sediment
removed from a channel bed or other low-lying parts of a
stream channel.
27
28. Weathering vs. Erosion
Weathering = process of disintegration or
decomposition of rocks which stay then in the
same place.
Erosion = process of disintegration or
decomposition of rocks which are transported
somewhere else.
28
29. Deposition
Deposition is the constructive process of accumulation
into beds or irregular masses of loose sediment or
other rock material by any natural agent;
29
30. Aggradation
Aggradation is the raising or elevating of a bottomland surface
through the process of alluvial deposition;
Conceptually it is the vertical component of accretion and is most
frequently applied to sediment deposition on a channel bed, bar
or other near-channel surfaces, flood plain, or, less often, low-
lying alluvial terrace.
30
31. Sedimentation
ď Sedimentation is the process by which sediment is
mechanically deposited from suspension within a fluid,
generally water, or ice, thereby accumulating as layers of
sediment that are segregated owing to differences in size,
shape, and composition of the sediment particles.
31
32. Mass movement/Mass Wasting
Mass movement is any downslope transfer, through
gravitational and generally water-facilitated (viscous)
processes, of near-surface soil and rock material;
Rates of mass movement range from very slow creep to nearly
instantaneous slope failure.

34. Faulting
Fault is a planar or gently curved fracture in the rocks of the
earthâs crust, where compressional or tensional forces cause
relative displacement of the rocks on the opposite sides of the
fracture.
34
35. Folding
Fold is an undulation or waves in the stratified rocks of the
earthâs crust.
A fold occurs when one or a mass of originally flat and planar
surfaces, such as sedimentary strata, are bent or curved as a
result of permanent deformation.
35
36. Volcanism
Volcanism is the phenomenon of eruption of molten
rock (magma) onto the surface of the earth, where lava
and volcanic gases erupt through a break in the surface
called a vent.
Eruption of the volcanoes or the magma is the main
sources of igneous rocks on the surface of the earth.
36
37. Earthquake
An earthquake is a vibration or oscillation of the surface of the
earth caused by sudden release of enormous pressure.
37
38. Landslide
A landslide, also known as a landslip, which includes a wide
range of ground movements, such as rock fall, deep failure of
slopes and shallow debris flows, which can occur in offshore,
coastal and onshore environments.
38
39. Diastrophism
ď Diastrophism is also called tectonism, large-scale
deformation of earthâs crust by natural processes, which leads
to the formation of continents and ocean basins, mountain
systems, plateaus, rift valleys, and other features by
mechanisms such as plate movement, volcanic loading, or
folding.
ď Internal forces active here
39
40. Metamorphism
Metamorphism is the change in rock structure, minerals or
geologic structure.
It is a process of change in the physical structure of rock as a
result of long-term heat, pressure and introduction of
chemically active fluids, especially a change that increases the
rock's hardness and crystalline structure.
The change occurs primarily due to heat, pressure, and the
introduction of chemically active fluids.
