What geographical processes affect the Great Barrier Reef?

What geographical processes affect the Great Barrier Reef?

The Great Barrier Reef has two clear Geomorphological (lithosphere) processes that occur in this ecosystem: 1) Earth Movements and 2) Weathering and Erosion.

What are biogeographical processes?

Biophysical Interactions – Biogeographical Processes modification: the change which takes place to an ecosystem as a result of the decline and increase of species and the introduction of new species.

What are the 3 processes that break down coral reefs?

(GA image) Physical breakdown of coral reefs is due to waves, winds, hurricanes, and currents. These may break apart the coral reef, forming grooves in the (once) circular reef.

How was the Great Barrier Reef formed geography?

13,000 years ago the sea level was almost where it is today and the reefs began to grow around off the coast of Australia islands. As these islands became further submerged with rising sea levels, the coral reefs grew over them to form the reef system present today.

How are human activities affecting the Great Barrier Reef?

Pollution, overfishing, destructive fishing practices using dynamite or cyanide, collecting live corals for the aquarium market, mining coral for building materials, and a warming climate are some of the many ways that people damage reefs all around the world every day.

What is an example of biogeography?

The definition of biogeography is the study of the places where animals and plants are distributed. An example of biogeography is classifying the floral region of South American as Neotropical, and the floral region of North American as Boreal. (uncountable) The study of the geographical distribution of living things.

What are the types of biogeography?

Today, biogeography is broken into three main fields of study: historical biogeography, ecological biogeography, and conservation biogeography. Each field, however, looks at phytogeography (the past and present distribution of plants) and zoogeography (the past and present distribution of animals).

What are the procedures in the coral reef ecosystem?

We propose a practical definition of coral reef functioning, centered on eight complementary ecological processes: calcium carbonate production and bioerosion, primary production and herbivory, secondary production and predation, and nutrient uptake and release.

What type of ecosystem is the Great Barrier Reef?

coral reef ecosystem
The Great Barrier Reef includes the world’s largest coral reef ecosystem with some 3000 coral reefs. Corals are marine invertebrates that are part of the same group as jellyfish and sea anemones. Corals are colonial animals (or polyps), where many coral polyps group together to form a coral colony.

What type of landform is the Great Barrier Reef?

Coral reefs are important marine landforms that have existed for hundreds of millions of years. They are composed of the dead skeletons of calcium carbonate (CaCO3 C a C O 3 ) based organisms. These are organisms with hard exoskeletons, and their skeletons provide a foundation for the next generation of organisms.

What are the environmental threats faced by the reef and its ecosystem?

Local Threats to 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 does tourism at the Great Barrier Reef affect the environment?

Impacts include physical damage to reefs and coral from boats, trampling and snorkelling, pollution from rubbish and human waste, wildlife disturbance where tourists aren’t maintaining a respectful distance and increased pressure from recreational fishing.

Is tourism affecting the Great Barrier Reef?

What are the three types of biogeography?

What is marine biogeography?

Marine biogeography is the study of marine species, the geographic distribution of their habitats, and the relationships between living organisms and the environment.

What is biogeography geography?

Biogeography is a broad and holistic science that examines spatial patterns of biological diversity. Biogeography is a subfield of the discipline of geography (or biology, depending on area of specialization), the study of the spatial distribution of phenomena over the earth.

What are 5 major abiotic factors in coral reefs?

Some of the abiotic factors that are specific to coral reefs are oxygen, water , carbon dioxide, sand, rocks, shells, temperature,light, hard substance, and waves.

How does climate change affect the Great Barrier Reef?

climate projections for the reef show that sea and air temperatures will continue to increase, sea level is rising, the ocean is becoming more acidic, intense storms and rainfall will become more frequent, and ocean currents will change.
