This presentation is for my school assessment on global environments. I chose coral reefs. My project explains coral reefs and the geographical processes involved with it as well.

Classification of marine environment pptAshish sahu
The main divisions of the marine environment. The two primary divisions of the sea are the benthic and the pelagic. The former includes all of the ocean floor, while the latter includes the whole mass of water. ... The deep-sea system is divided into an upper (archibenthic) and a lower (abyssal-benthic) zone.
Coral bleaching occurs when coral polyps expel algae that live inside their tissues. Normally, coral polyps live in an endosymbiotic relationship with these algae, which are crucial for the health of the coral and the reef. The algae provides up to 90 percent of the coral's energy.
hen water is too warm, corals will expel the algae (zooxanthellae) living in their tissues causing the coral to turn completely white. This is called coral bleaching. When a coral bleaches, it is not dead. Corals can survive a bleaching event, but they are under more stress and are subject to mortality.
Marine Scoops Guide To Coral Reefs (Part 1/3)Marine Scoop
A brief introduction to coral biology, reef formation and coral reproduction. Check out more at www.marinescoop.com and sign up to our weekly newsletter to receive parts II and III as soon as they are released! Part II will cover natural threats to coral reefs, coral bleaching, reef pollution, reef sedimentation, coral reef acidification and coral disease. Part III will cover overexploitation of reefs, destructive fishing practices on reefs, coral reef management and marine protected areas. Feel free to suggest another marine ecosystem to cover!

How to Make a Field invisible in Odoo 17Celine George
It is possible to hide or invisible some fields in odoo. Commonly using “invisible” attribute in the field definition to invisible the fields. This slide will show how to make a field invisible in odoo 17.
How to Split Bills in the Odoo 17 POS ModuleCeline George
Bills have a main role in point of sale procedure. It will help to track sales, handling payments and giving receipts to customers. Bill splitting also has an important role in POS. For example, If some friends come together for dinner and if they want to divide the bill then it is possible by POS bill splitting. This slide will show how to split bills in odoo 17 POS.
The Art Pastor's Guide to Sabbath | Steve ThomasonSteve Thomason
What is the purpose of the Sabbath Law in the Torah. It is interesting to compare how the context of the law shifts from Exodus to Deuteronomy. Who gets to rest, and why?

The Indian economy is classified into different sectors to simplify the analysis and understanding of economic activities. For Class 10, it's essential to grasp the sectors of the Indian economy, understand their characteristics, and recognize their importance. This guide will provide detailed notes on the Sectors of the Indian Economy Class 10, using specific long-tail keywords to enhance comprehension.

2. Coral reefs are massive structures made of limestone deposited
by living things. Although thousands of species inhabit coral
reefs, only a fraction produce the limestone that builds the reef.
The most important reef-building organisms are the corals.
Corals are sessile animals, meaning they are not mobile but stay
fixed in one place. They feed by reaching out with tentacles to
catch prey such as small fish and planktonic animals.
3. Corals live in colonies consisting of many
individuals, each of which is called polyp.
They secrete a hard calcium carbonate
skeleton, which serves as a uniform base
or substrate for the colony. The skeleton also
provides protection, as the polyps can
contract into the structure if predators
approach. It is these hard skeletal structures
that build up coral reefs over time.
4. There are three main types of Coral reefs, these are :
1. Coral atolls- which are rings of coral that create
protected lagoons and are usually located in the middle
of the sea. Atolls usually form when islands surrounded
by fringing reefs sink into the sea or the sea level rises
around them (these islands are often the tops of
underwater volcanoes).
5. 2. Barrier reefs- are parallel to the coastline but are
separated by deeper, wider lagoons. At their
shallowest point they can reach the water's surface
forming a "barrier" to navigation. The Great Barrier
Reef in Australia is the largest and most famous
barrier reef in the world
3.Fringing reefs- grow near the coastline around
islands and continents. They are separated from the
shore by narrow, shallow lagoons. Fringing reefs are
the most common type of reef that we see for
example the Buccoo reef in Tobago ;-)
10. Coral reefs provide COASTAL PROTECTION by slowing
down waves that would otherwise break directly on
the shore. These waves can be destructive and
damage unprotected sea-front property.
11. Coral reefs also protect other ecosystems, like sea-
grass meadows and mangroves. These ecosystems
provide us with many important ecosystem services
like water purification and food.
In addition coral reefs protect coastlines from
tropical storms and tsunamis. This protection is
likely to become more important as climate change
is predicted to make tropical storms more frequent
and destructive
12. Coral reefs comprise one of the most diverse
ecosystems on earth, and are home to over one
million species unfortunately, human interaction
with coral reefs are causing them to be destroyed
at such a high rate that already 10% of coral reef
habitat has been destroyed, and within the next 20
– 40 years up to 60% will be destroyed.
13. The majority of coral reef destruction can be
blamed on human practices. Fisheries often use
extremely destructive methods in order to catch
fish, such as blast fishing (setting off dynamite to
stun fish) or cyanide fishing (using poison to stun
fish).
The sustainability of the fishing industry will then
depend on educating fishermen about the
importance of coral reefs and the role they play.
14. Protects coastline from the destructive waves and storm
surges as they act as a barrier and so prevent beach erosion.
Provide harbours and beaches
Tourist attraction ( diving, photography) which generates
much needed foreign exchange for the region.
15. Breeding ground for fish and other marine life
thus impacting on lives of people along coast
and especially in Caribbean where island culture
exists – fisher folks and so destruction would
result in change in their livelihood.
Habitats, shelter and food for marine fauna and
flora .
Provides aesthetic value to region
16. Coastal development; construction of hotels, marinas provide
turgid waters choke coral growth.
Silt from land due to run off destroy coral organisms
Fertilizer run off from farm lands as well as oil spills destroy
marine life.
17. Damages caused by recreation and tourism-
anchors, boat grounding.
Over exploitation by fishermen.
Destructive fishing methods such as dragging fish
net, dynamiting.
Global warming will result in rise in sea level.
Waters will become too deep for corals to survive.
