What happens due to coral reef damage by El Niño? a. The ocean water gets warmer. …
The reef supports more diversity of life.
Is coral bleaching caused by El Niño?
The events are driven by changes in the Pacific Ocean, but have global climate impacts–and in
El Niño
years, we often observe coral bleaching events. During El Niño years, a swath of warm ocean water sweeps across the entire Pacific basin from west to east, leaving bleached and dying corals in its wake.
What is the effects of El Niño?
El Niño conditions can cause a wide range of health problems, including
disease outbreaks, malnutrition, heat stress, and respiratory diseases
. The risk of communicable diseases increases when there is limited access to food, water, and sanitation.
Which describes the negative effects of El Niño?
Which statement describes the negative effects of El Niño?
Rain, flash floods, and mudslides occur in places where there is usually little rain, while usually wet areas suffer from drought
. Upwelling is a process in which warm, nutrient-rich water from the deep ocean rises to the surface.
How does weather affect the coral reef?
As temperatures rise,
mass coral bleaching events and infectious disease outbreaks
are becoming more frequent. … Climate change will affect coral reef ecosystems, through sea level rise, changes to the frequency and intensity of tropical storms, and altered ocean circulation patterns.
How does El Niño affect climate?
El Niño can affect our weather significantly. … El Niño
causes the Pacific jet stream to move south and spread further east
. During winter, this leads to wetter conditions than usual in the Southern U.S. and warmer and drier conditions in the North. El Niño also has a strong effect on marine life off the Pacific coast.
What are the causes and effects of El Niño?
An El Niño condition occurs
when surface water in the equatorial Pacific becomes warmer than average and east winds blow weaker than normal
. The opposite condition is called La Niña. During this phase of ENSO, the water is cooler than normal and the east winds are stronger. El Niños typically occur every 3 to 5 years.
Is La Nina good for coral?
Cooling La Niña may not save
Great Barrier Reef from mass coral bleaching, experts warn. A global weather phenomenon that would typically keep ocean temperatures lower across the Great Barrier Reef may not be enough to stop another mass coral bleaching this coming summer, according to the marine park's chief scientist.
How does El Niño affect coral growth?
In a severe bleaching event, large swaths of reef-building corals die. This causes reefs to erode, destroying fish habitat and exposing previously protected shorelines to the destructive force of ocean waves.
Warmer ocean temperatures
caused by El Niño and global warming can lead to coral bleaching.
What causes mass coral bleaching?
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 are the impacts of El Niño and La Niña in our society?
El Niño and La Niña
affect not only ocean temperatures, but also how much it rains on land
. Depending on which cycle occurs (and when), this can mean either droughts or flooding. Typically, El Niño and its warm waters are associated with drought, while La Niña is linked to increased flooding.
What countries does El Niño effect?
El Niño has been linked with drought not just in parts of Latin America but in
southeastern Africa, South Asia, Indonesia and Australia
. It has also been associated with steep declines in fish stocks, including the 1972 collapse of the world's largest fishery, the Peruvian anchoveta.
Do coral reefs produce oxygen?
Most corals, like other cnidarians, contain a symbiotic algae called zooxanthellae, within their gastrodermal cells. … In return,
the algae produce oxygen
and help the coral to remove wastes.
How are humans killing coral reefs?
Coral reefs face many threats from local sources, including:
Physical damage or destruction from coastal development
, dredging, quarrying, destructive fishing practices and gear, boat anchors and groundings, and recreational misuse (touching or removing corals).
How can we save coral?
- Recycle and dispose of trash properly. Marine debris can be harmful to coral reefs. …
- Minimize use of fertilizers. …
- Use environmentally-friendly modes of transportation. …
- Reduce stormwater runoff. …
- Save energy at home and at work. …
- Be conscious when buying aquarium fish. …
- Spread the word!
Is La Nina warm or cold?
La Nina refers to the
periodic cooling of ocean surface temperatures
in the central and east-central equatorial Pacific. Typically, La Nina events occur every 3 to 5 years or so, but on occasion can occur over successive years. La Nina represents the cool phase of the El Nino/Southern Oscillation (ENSO) cycle.
