The Atlantic is relatively a narrow body of water. It exists between two parallel continental masses.
The Atlantic Ocean touches both the Europe and the Africa on its eastern side. It is bounded by North America and South America along its western region. The Atlantic has no definite northern or southern boundaries. It runs into the Arctic Ocean on the north, and the Antarctic Ocean on the south. Some geographers consider the Arctic Circle as its northern boundary, and the Antarctic Circle as its southern boundary. The ancient Romans named the Atlantic after the Atlas mountains. These mountains rose at the western end of the Mediterranean sea.
An ocean (from Ancient Greek Ὠκεανός, transc. Okeanós, the sea of classical antiquity[1]) is a body of saline water that composes much of a planet's hydrosphere.[2] On Earth, an ocean is one of the major conventional divisions of the World Ocean, which covers almost 71% of its surface. These are, in descending order by area, the Pacific, Atlantic, Indian, Southern (Antarctic), and Arctic Oceans.[3][4] The word sea is often used interchangeably with "ocean" in American English but, strictly speaking, a sea is a body of saline water (generally a division of the world ocean) partly or fully enclosed by land.[5]
The sphere of water on earth refers to the hydrosphere.
It encompasses all the water present in seas, oceans, lakes, rivers, reservoirs, ice caps, soil moisture, water vapor in the atmosphere and also as groundwater.
Among all these, ocean stands as a principal component of the hydrosphere. About 97 per cent of all the water available on the earth are existing as oceans. This module explains the global seas and oceans.
After attending this lesson, the learner should be able to comprehend about the geographic setting of the Pacific ocean, its dimension, associated water masses, morphological features of the ocean floor, very significant conditions of the ocean, sediments, marine life, marine pollution and other hazards. In addition the user should be able to understand, the importance of the Pacific in the context of global activities including the historical oceanographic explorations.

71% of the Earth’s surface is covered by ocean water.
The oceans contain 97% of the earth’s water.
All the oceans and seas are actually one continuous body of water.
The subject of studying the physical, chemical and biological conditions of oceans is called as Oceanography.
It is an inter-disciplinary subject and an emerging area for marine engineering. It is the science of seas and oceans.
Seas and Oceans are blue beauties of the planet earth.
Oceans are vast body of saline water occupying the great depressions on the earth. The surface beneath the oceanic waters is characterized by a lot of relief features.
The structure, configuration and relief features of the oceans also vary from each other.On the basis of Bathymetry and other studies, the morphology of Ocean basins contains a lot of relief features. This module highlights many of those features.

Microbial characterisation and identification, and potability of River Kuywa ...Open Access Research Paper
Water contamination is one of the major causes of water borne diseases worldwide. In Kenya, approximately 43% of people lack access to potable water due to human contamination. River Kuywa water is currently experiencing contamination due to human activities. Its water is widely used for domestic, agricultural, industrial and recreational purposes. This study aimed at characterizing bacteria and fungi in river Kuywa water. Water samples were randomly collected from four sites of the river: site A (Matisi), site B (Ngwelo), site C (Nzoia water pump) and site D (Chalicha), during the dry season (January-March 2018) and wet season (April-July 2018) and were transported to Maseno University Microbiology and plant pathology laboratory for analysis. The characterization and identification of bacteria and fungi were carried out using standard microbiological techniques. Nine bacterial genera and three fungi were identified from Kuywa river water. Clostridium spp., Staphylococcus spp., Enterobacter spp., Streptococcus spp., E. coli, Klebsiella spp., Shigella spp., Proteus spp. and Salmonella spp. Fungi were Fusarium oxysporum, Aspergillus flavus complex and Penicillium species. Wet season recorded highest bacterial and fungal counts (6.61-7.66 and 3.83-6.75cfu/ml) respectively. The results indicated that the river Kuywa water is polluted and therefore unsafe for human consumption before treatment. It is therefore recommended that the communities to ensure that they boil water especially for drinking.

UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
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.

Climate Change All over the World .pptxsairaanwer024
Climate change refers to significant and lasting changes in the average weather patterns over periods ranging from decades to millions of years. It encompasses both global warming driven by human emissions of greenhouse gases and the resulting large-scale shifts in weather patterns. While climate change is a natural phenomenon, human activities, particularly since the Industrial Revolution, have accelerated its pace and intensity
"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
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.
3. Some basic info. about
oceanography
• Founder of Oceanography is unknown.
• Can also referred as “oceanology” and “marine
science”.
• In short, oceanography is a science that deals with
the ocean.
• It is a science that deals with the oceans and
includes the delimitation of their extent and depth,
the physics and chemistry of their waters, marine
biology, and the exploitation of their resources.
5. World land and water bodies
• Earth is referred as “Blue planet” of the galaxy.
• 71 percent of the Earth's surface is covered with
water (known as ocean, Sea, rivers, ponds, lakes,
etc.)
• the land has its contribution of 29% (including
islands, continents, etc.)
6. Earth land
• referred as dry land
• support agriculture, habitat, and various natural
resources
7. Water bodies
• any significant accumulation of water, generally on
a planet's surface.
• often refers to oceans, seas, and lakes
• Most are naturally occurring geographical features
(e.g, ocean,sea,river etc)
• some are artificial (e.g, canal, ponds, lakes etc)
10. Origin of the ocean
- Earth is about 4.5 billion years old but oceans are
3.8 billion years old.
Main theories describing how oceans are created:-
1: Earth was formed with water and that this water
come from the inside out
2: Earth was dry planet with brought here by other
sources via meteorite impacts
11. Formation of ocean goes from 3
phases
-initially there was only water vapor in atmosphere
-Air and ground surface too hot for liquid
-Cooling of atmosphere led to condensation and rain
-Ground surface still too hot for pooling
-Further cooling of the ground surface finally led to
accumulation of liquid water on surface
