Every continent or island is bordered by a long or short coastline. Coastline is the line separating the land and sea. Coastal zones are the transition zones between terrestrial and marine habitat. They form an interface between land and oceanic natural processes. Coastal areas also are varied in their topography, climate and vegetation. Some are sandy beaches, rocky shores, with or without tidal inlets. The climate of a coast are controlled by the land and sea breezes and the humidity controlled by marine water. Waves are powerful tools for constructive and destructive activities. Hence. the geomorphology of beach, materials and processes are always not constant due to the impact of everlasting action of tides, waves and currents.

The study of physical oceanography helps in understanding all these aspects in detail. Let us see most of these factors and processes in our future modules. Mathematical models of all these processes are also developed using these phenomena and mechanisms. The individual aspects of all the elements of physical oceanography are to be studied in detail.
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.
This ppt contains the information about the ocean life. The description about the ocean layers then animals stays in ocean in different layers etc...This may be very interesting.
Oceanography is the science that studies the oceans along with marine organisms and ecosystem dynamics, ocean currents and waves, plate tectonics and the geology of the sea floor, and the chemical substances and physical properties of the world oceans.

Here is a 45 minute lesson I created in Korea focusing on the Ocean. Students guessed words concerning the ocean, we discussed the BP oil spill, and students were then allowed to create their own ocean-dwelling creatures.
Main steps to build a digital library:
Data collection and digitization
Metadata selection and designing the digital library interface
Annotation of digitized data (may be word spotting as well)

Most of the earth is covered by ocean waters. Oceans are very important. They affect weather, and because of uneven heating from the sun, currents of warmer water flow through colder ocean water. Winds cause waves.
Biological oceanography gradually grew into a major scientific discipline with all these observations of marine organisms and their environments. In this episode, the following modules are highlighted:1. Nature of marine environment, 2. Classification of Marine environment, 3. Role of abiotic parameters on marine life, 4. Marine Flora , and 5. Marine Fauna.

Unit Lesson
It is easy to see why Earth is referred to as the “Blue
Planet”—71% of the Earth’s surface is covered by
oceans and seas. However, less than 5% of our
oceans have been explored (National Oceanic and
Atmospheric Administration [NOAA] 2014). So
essentially, most of our Earth is still unexplored and
largely unknown. We do know that oceans contain the
highest mountains, the deepest trenches, and the
longest mountain ranges. On average, the ocean
depth is about four times the average elevation of
continents. In fact, Lutgens & Tarbuck (2014) state that
if the Earth’s continents were perfectly flat, they would
be completely submerged under more than 2,000
meters of seawater!
Oceanography is the branch of science that studies
the world’s oceans. It includes geology, chemistry,
physics, and biology (Lutgens & Tarbuck, 2014).
Oceanographers started mapping the oceans floors as
early as 1872 by dropping weighted lines down to the
ocean bottom at random points. The use of sound navigation and ranging (sonar) began during World War I
to detect enemy submarines, and was later improved during World War II. Sonar uses the echo of sound
waves to plot the profile of the ocean floor. Satellite radar technology has also contributed to mapping the
ocean floor. Today, we have a fairly good picture of the ocean floor topography.
As we study the ocean floor, we notice three major features: continental margins, basin floors, and mid-
oceanic ridge. The continental margins can be classified as active or passive. Active margins are where the

ocean lithosphere is subducted beneath the continental crust (recall what you learned in Units III and IV).
These are mainly found around the Pacific Ocean. Passive margins are those that are not experiencing plate
tectonic activity and have more stable topography. Basin floors make up about 30% of the Earth’s surface
(Lutgens & Tarbuck, 2014). These areas are between the margins and the mid-ocean ridges and include
deep trenches, under ...

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

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.
