How does precipitation affect coral reefs?
Changes in storm patterns: leads to stronger and more frequent storms that can cause the destruction of coral reefs. Changes in precipitation:
increased runoff of freshwater, sediment, and land-based pollutants contribute to algal blooms
and cause murky water conditions that reduce light.

What is Great Barrier Reef bleaching?
When 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.
What is the terrain of the Great Barrier Reef?
Geography. The reef actually consists of
some 2,100 individual reefs and some 800 fringing reefs

What is precipitation in hydrological cycle?
Precipitation is
water released from clouds in the form of rain, freezing rain, sleet, snow, or hail
. It is the primary connection in the water cycle that provides for the delivery of atmospheric water to the Earth. Most precipitation falls as rain.
What is coral rain?
When corals and the algae that live on them are under stress, such as from higher water temperatures, they emit increasing amounts of a substance called
dimethyl sulphide or DMS
. … When the particles have absorbed enough water, it rains … across the reef and over the farms and rainforests of North Queensland.
What is destroying the Great Barrier Reef?
According to the GBRMPA in 2014, the most significant threat to the status of the Great Barrier Reef is
climate change
, due to the consequential rise of sea temperatures, gradual ocean acidification and an increase in the number of “intense weather events”.

yes
, but in general, they are mostly harmless to humans. The most common sharks found on the Great Barrier Reef are white tip and black tip reef sharks.
Is the water in Australia warm?

are the Traditional Owners of the Great Barrier Reef area and have a continuing connection to their land and sea country.
Why is the Great Barrier Reef so big?
The Great Barrier Reef can be seen from outer space and is
the world's biggest single structure made by living organisms
. This reef structure is composed of and built by billions of tiny organisms, known as coral polyps. It supports a wide diversity of life and was selected as a World Heritage Site in 1981.
Is the Great Barrier Reef salt or freshwater?
Light penetrates the ocean surface only about 20 meters.
There is much more salt in the Great Barrier Reef than in a freshwater ecosystem
, and some biotic components that live near estuaries, where fresh water mixes with salt water, have to deal with changing amounts of salt in the water.
How old is the Great Barrier Reef?

Do coral reefs absorb CO2?
Coral reefs are important in determining the amount of carbon dioxide in the atmosphere. The zooxanthellae algae, through
photosynthesis
, remove carbon dioxide from the air and make carbohydrates available as food for both the zooxanthellae and the coral polyps.
How much CO2 does the Great Barrier Reef absorb?
Trends. The pH of seawater has remained steady for millions of years, and marine life has evolved based on the ocean's delicate chemical balance. However, the oceans are estimated to have absorbed
about 30 per cent of
the emitted carbon dioxide from human activities since pre-industrial times.
Why do zooxanthellae leave coral?
When the reef is under stress from high temperatures, pollution, or other threats, the zooxanthellae abandon their coral hosts in a process called
“bleaching
.” The coral animals can survive for a short time without their main food source by catching particles from the water with their tentacles, but they are more …
Why do corals expel their zooxanthellae when stressed?
In general, when corals experience a thermal stress, the algae that exist within the coral tissues, they're symbiotic zooxanthellae, the corals will expel them. … They're
breaking up pieces of tissue to get rid of
this, to slough it off.

What problems are the Great Barrier Reef facing?
The Reef is highly vulnerable. In the past three decades, it has lost half its coral cover,
pollution
has caused deadly starfish outbreaks, and global warming has produced horrific coral bleaching. Coastal development also looms as a major threat.
Can zooxanthellae survive without coral?
They would not be able to survive without them
since they can't produce sufficient amounts of food. The zooxanthellae can provide all the nutrients necessary, in most cases all the carbon needed for the coral to build the calcium carbonate skeleton.
What is coral bleaching caused by?
The leading cause of coral bleaching is
climate change
. A warming planet means a warming ocean, and a change in water temperature—as little as 2 degrees Fahrenheit—can cause coral to drive out algae. Coral may bleach for other reasons, like extremely low tides, pollution, or too much sunlight.

What geographical processes created the Great Barrier Reef?
Corals began to form around the base of these mountains, which at the time were continental islands. Once sea levels began to rise, the growth of coral began to creep up the mountains, which were eventually completely submerged, leaving behind small islands, barrier reefs and atolls that we know and see today.
