The grand canyon
Over billions of years, the area that is now the Grand Canyon transformed from tall mountains to a flat plain and was later uplifted by tectonic activity. Around 12 million years ago, the Colorado River was dammed and formed a huge lake, Lake Bidahochi. Around 5.5 million years ago, the river reconnected in a new channel and began cutting through the plateau, forming the Grand Canyon over millions of years of erosion from water and weathering. The Grand Canyon continues changing today through ongoing erosion.

Sea floor spreading2
Sea-floor spreading is the process that continually adds new material to the ocean floor. Molten material rises up from the mantle at mid-ocean ridges and erupts, pushing the oceanic plates apart as it cools and forms new crust. Evidence for sea-floor spreading includes pillow basalts and magnetic stripe patterns in the ocean crust that record reversals in Earth's magnetic field. Drilling samples also show that rocks get progressively older farther from mid-ocean ridges. Subduction is the process where oceanic plates plunge back into the mantle at deep-sea trenches, allowing the ocean floor to continuously renew itself over hundreds of millions of years.
Historical Geology Study Guide
Scientists study the Earth's history by examining rocks and dating them. The geological time scale divides Earth's lifetime into eras based on layers of rock and fossils. Relative dating involves placing rocks in proper sequence, while radiometric dating uses radioactive decay to determine ages. The oldest fossils date to around 3.8 billion years ago. Major periods include the Paleozoic, Mesozoic, and Cenozoic eras. Mass extinctions occurred, like at the end of the Permian, possibly due to asteroid impact. Humans have significantly impacted geology through pollution, deforestation, and species extinction.
The geologic time scale 1
The geologic time scale shows the eras and periods of Earth's history. During the Jurassic period of the Mesozoic era, dinosaurs like T-Rex and Velociraptor lived. A meteor wiped out the dinosaurs and allowed mammals to evolve and dominate. Early humans were cavemen that evolved to become smarter and build the first civilizations. The document provides an overview of major events and periods within the geologic time scale.

Continental drift theory bsc.sem ii final
Continental drift theory proposes that the continents were once joined together and have since drifted apart. It was proposed by German geologist Alfred Wegener to explain the arrangement of continents. Wegener noted evidence like similar fossil and rock formations between continents, as well as geological features that suggested continents were once in different positions, like coal deposits that now span different climate zones. He hypothesized that around 300 million years ago, all the continents were joined together in a single landmass called Pangaea, which later broke apart due to forces like gravity and tidal forces from the sun and moon, causing the continents to drift to their current positions.

Devonian period(3)
The document discusses the Devonian period and various Devonian fossil sites. It begins by explaining the etymology of the term "Devonian" from Devon, England where the rocks were first studied. It then describes three specific Devonian fossil sites - a fossil gorge in Iowa discovered after flooding where crinoids, brachiopods and coral can be found, fossil beds in Indiana and Kentucky originally part of the Ohio River featuring rugosan corals, brachiopods and trilobites, and formations in Oklahoma containing over 30 trilobite species.
Land bridge
A land bridge, in biogeography, is an isthmus or wider land connection between otherwise separate areas, over which animals and plants are able to cross and colonise new lands. A land bridge can be created by marine regression, in which sea levels fall, exposing shallow, previously submerged sections of continental shelf; or when new land is created by plate tectonics; or occasionally when the sea floor rises due to post-glacial rebound after an ice age.
Land pollution
Soil contamination or soil pollution as part of land degradation is caused by the presence of xenobiotic chemicals or other alteration in the natural soil environment

Hang Son Doong cave in Vietnam is the largest cave in the world. In 1991 the cave was discovered by Ho-Khanh but it wasn't until 2009 when British scientists surveyed it that its full scale was realized. The cave passages can fit an entire New York City block and contains forests, rivers, and even clouds inside. National Geographic documented the cave in 2010, finding enormous chambers over 5 kilometers long, 200 meters high, and 150 meters wide. The cave remains largely unexplored with many passages still undiscovered.
World’s largest cave
Son Doong is the world's largest cave, located in Vietnam. It is over 200 meters high and 150 meters wide in places. The cave was originally discovered in 1991 by a Vietnamese man but an international team explored it further in 2009, finding an underground river and stalagmites over 70 meters tall. At over 6.5 km long so far, it exceeds the previous largest cave and its remote and concealed location made it difficult for explorers to find previously.
Caves
Caves are formed over long periods of time by the erosion of soluble rocks like limestone by water and carbon dioxide. They occur in different types around the world, including limestone caves, lava tubes, sea caves, and sinkholes. Caves provide important ecosystems for organisms adapted to permanent darkness. However, human activities like vandalism and pollution threaten cave environments. Conservation efforts aim to preserve caves and educate visitors on protecting these fragile geologic wonders.

The goal is to provide students with knowledge about underground waters as part of the hydrosphere. The lesson will deepen students' understanding of the hydrosphere and examine the conditions for underground water formation. Students will learn about different types of underground waters like surface water, soil water, interlayer waters, and artesian waters. The lesson aims to explain the importance of underground waters to humans and encourage careful stewardship of water resources. The lesson will use maps, atlases, textbooks, assignment cards, schemes and tables.
Romania is my country 1
Romania has many unique natural wonders, including the Retezat massif which contains 90 plant species found nowhere else and the best preserved delta in Europe. Other areas include the Bucegi Plateau home to attractions like the Sphinx and Babele rock formations, the Danube Delta biosphere reserve and largest wetland in Europe, and the pristine beach of Gura Portiței in the delta. Additional geological features are the Muddy Volcanoes nature reserve known for eruptions of mud and water, and the Fortress of Ponor cave system within the Apuseni Mountains containing an underground river.
Blue Holes
Here are potential responses to the questions:
1. Cynobacteria is found in the top layer of blue holes because it is anaerobic and can survive without oxygen. The conditions in the top layer of blue holes with no light and low oxygen suit cyanobacteria.
2. Organisms at the bottom of blue holes might be adapted to high pressure, no light, anaerobic conditions. They could rely on chemosynthesis rather than photosynthesis and be able to withstand very low oxygen levels.
3. Stalactites are hanging formations that grow downwards from the ceilings of caves, formed by mineral deposition. Stalagmites are upward projections from cave floors, formed in the same way.

The document also discusses the functions of marine geologists in exploring and studying the ocean floor to better understand the Earth.
Four types of caves
Solution caves are the most common type of cave, formed by groundwater dissolving carbonate rocks like limestone along joints and fractures. The document discusses four main types of caves - solution caves, lava tubes, sea caves eroded by wave action, and glacier caves formed by meltwater. It also covers related topics like karst terrain and its significance for infrastructure planning, as well as cave formation processes and risks of building in cave-prone coastal areas.

Caves
Caves form naturally underground from weathering of rock. There are several types of caves including sea caves formed by wave erosion, lava caves formed by volcanic processes, and glacier caves within glacial ice. Examples visited include sea caves in Oregon home to sea lions, lava tubes in Hawaii's volcanoes national park, and glacier caves in Alaska's Mendenhall Valley glacier experiencing retreat from global warming. While caves can be tourist attractions, they are fragile ecosystems impacted by human waste and trash if visitors do not respect the environment.

A Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Hang sondoongcavern
- 1. Hang Son Doong World’s Largest Cavern Discovered In Viet Nam in1991 meaning Mountain River Cave
- 4. British scientists from the British Cave Research Association, led by Howard and Deb Limbert, conducted a survey in Phong Nha-Ke Bang from April 10-14, 2009
- 5. Hidden in rugged Phong Nha-Ke Bang National Park near the border with Laos, the cave is part of a network of 150 or so caves, many still not surveyed, in the Annamite Mountains
- 6. It took six hours trekking through the jungle to reach the cave.
- 7. Climbing down into a large chamber, they had to negotiate two underground rivers before reaching the main passage of the Hang Son Doong .
- 9. The cave is located near the Laos-Vietnam border.
- 10. Hang Son Doong, in the Phong Nha-Ke Bang National Park in Vietnam, was discovered by Ho-Khanh in 1991. However it wasn't until 2009, when Howard and Deb Limbert surveyed the cave, that the full extent of the cave was made know.
- 12. The cave is considered to be the world's largest. One of it's caverns could fit an entire New York City block of skyscrapers! The cave holds a river and a jungle. There are even clouds down there!
- 13. National Geographic sent a team to document the cave in 2010. Carsten Peter's stunning photo's were featured in the January 2011 issue and should not be missed.
- 16. Like a petrified waterfall, a cascade of fluted limestone, greened by algae, stops awestruck cavers in their tracks.
- 18. Rare cave pearls fill dried-out terrace pools near the Garden of Edam in Hang Son Doong. This unusually large collection of stone spheres formed drip by drip over the centuries as calcite crystals left behind by water layered themselves around grains of sand, enlarging over time.
- 20. The biggest chamber of Son Doong is over five kilometers in length, 200 meters high and 150 meters wide.
- 21. The cave which had never been entered before by anyone including local jungle people because the entrance which is small by Vietnamese cave standards (10m high and 30m wide) emitted a frightful wind noise which was due to the large underground river."
- 22. The cave is over 6 km. long Collapsed doline -mini jungle one quarter mile below the surface
- 23. An enormous shaft of sunlight plunges into the cave like a waterfall. Between us and the sunlit passage ahead stands a stalagmite that in profile resembles the paw of a dog.
- 24. “ The Hand of God would be just too corny,” he says, pointing at the formation. “But the Hand of Dog does nicely, don’t you think?”
- 25. Collapsed Doline -a mini jungle one quarter of a mile below the surface Dolines are created when a cave system ceiling collapses inwards allowing daylight to stream in and create new and unique ecosystems. A new species of wood louse (non-pigmented and blind) was discovered in a dry side passage. The plants in this area exhibited an adaptation called “ phenotropic plasticity” meaning changes in response to the environment.
- 26. Looking up towards one of the collapsed ceilings of the cave
- 27. The hole in the ceiling through which the light cascades is unbelievably large, at least 300 feet across. The light, penetrating deep into the cave, reveals for the first time the mind-blowing proportions of Hang Son Doong.
- 28. Dolines are created when the cave ceiling collapses inwards allowing daylight to stream in and create new and unique ecosystems.
- 30. Measuring 200m high and 150m wide this new cave is believed to be almost twice the size of the current record holder which is the Deer Cave in Malaysia .
- 31. Why did it get so big? The perfect formula was: huge volumes of water, it was tropical and the river followed a narrow fault line.
- 34. Collapsed doline -mini jungle one quarter mile below the surface
- 35. It is amazing that we are still discovering places this spectacular!
- 37. After exploring the cave passage for six kilometers, their way was barred by a formidable and gigantic calcite rock face they named ‘The Great Wall of Vietnam."
- 39. After scaling the “Great Wall of Viet Nam” it was found that the cavern system ended.
- 40. Hang Son Doong
