Mail all 9:04 PM X Geo formations1.pdf ah -103 Name ID: Date: Geological Formation Research Directions: In class, we discussed the importance of various geological formations for the discovery of fossil fuels. Using the template below, conduct a short survey on a geological landform or body of woter. You may, for example, research a significant reef, such as the Great Barrier Reef in Austrolia in this case, you would focus your answers on this particular form. Also, be sure to answer each question below in complete sentences using the grammar and vocabulary covered in class. 10pts 1. Geological formation 1pt 2 Where is it located? (you may attach mapl 1pt How was this geological feature formed? 2pts 4 Explain which aspect of the rock cycle is this form most closely associated with? ie. sedimentation, igneous extrusion, metamorphism, etc) 2pts What types of organic-rich rock may be found there? Give 2 examples. 2pts 6. Citation (Use APA format) 2pts

Explanation / Answer

1)A continuous underground formation with homogenous property to be considered as a single unit is geological formation. These formations with specific structure and porosity provide an opportunity to be used as a storage site. Examples of such formations include depleted oil and gas fields, unmineable coal seams, saline aquifers and shale formations.

3)The geologic formation of the Great Barrier Reef is long and complex. Coral reefs began forming in the region about between 58 and 48 million years ago when the Coral Sea Basin formed.However, once the Australian continent moved to its present location, sea levels began to change and coral reefs started to grow quickly but changing climate and sea levels after that caused them to grow and decline in cycles. This is because coral reefs need certain sea temperatures and levels of sunlight to grow.

Today, scientists believe that complete coral reef structures where today's Great Barrier Reef are were formed 600,000 years ago. This reef died off however due to climate change and changing sea levels. Today's reef began to form about 20,000 years ago when it started growing on the remains of the older reef. This due to the fact that the Last Glacial Maximum ended around this time and during glaciation sea level was much lower than it is today.

Following the end of the last glaciation about 20,000 years ago, sea level continued to rise and as it got higher, the coral reefs grew on the hills being flooded on the coastal plain. 13,000 years ago 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. The current Great Barrier Reef structure is about 6,000 to 8,000 years old.

5)Limestone is an organic rock found The main structure of coral is formed from each polyp as they secrete calcium carbonate (CaCO3) from the surrounding seawater and use this to form the coral’s skeleton. This is how reefs build up to form great masses, and what’s even neater is that the calcium carbonate skeleton forms rocks called limestone
