Quaternary Geomorphology Final Project

Quaternary Geomorphology Final Project

• Sezgin Kalay completed a final project on Quaternary Geomorphology.

Question 1

• Active volcanoes in Anatolia during the Quaternary period are concentrated in different regions.
• Eastern Anatolia: Nemrut, Süphan, and Tendürer mountains show volcanic activity.
• Central Anatolia: Erciyes, Hasan Dağı, and Karacadağ are volcanic areas.
• Western Anatolia: Kula is known for its volcanic cones and spreading lava flows.
• Southern Anatolia: Karacadağ displays extensive basalt flows.

Volcanic Landforms and Features

• Shield Volcanoes: Examples like Karacadağ are characterized by broad bases and gently sloping sides, formed by basaltic lava flows.
• Stratovolcanoes: Erciyes and Hasan Dağı are examples, characterized by layered lava and pyroclastic flows.
• Cinder Cones: These are simpler, cone-shaped structures formed by pyroclastic material.
• Calderas: The Nemrut volcano in Eastern Anatolia displays a caldera structure, a large depression formed after a volcanic eruption's collapse.
• Volcanic Landforms: Various shapes and structures were created by active volcanism.

Geomorphological Impacts

• Lava Flows: Extensive lava flows covering broad terrains.
• Volcanic Cones: Various shapes and forms created during the Quaternary period.
• Volcanic Zones: Distribution of volcanic features across various regions.
• Landslides: This phenomenon is a common result of volcanic activity.
• Earthquakes: Several earthquakes have affected volcanic areas.

Question 2

• Tsunami Formation: Tsunamis are typically generated by large-scale underwater disturbances like earthquakes and submarine volcanic eruptions.
• Earthquake-Generated Tsunamis: Earthquakes with significant magnitude and beneath the seafloor create powerful tsunamis.
• Volcanic-Generated Tsunamis: Large submarine volcanic eruptions can displace enormous volumes of seawater, potentially producing tsunamis.
• Mechanism: Displacement of large volumes of water.
• Wave Propagation: Deep-water tsunami waves have low height and high speed.
• Nearshore Characteristics: As the wave approaches the shore, the water depth decreases, causing the height to increase, and speed/velocity reduces.
• Onset: Initial impact characterized by a significant sea level change.
• Coastal Impacts: Tsunamis can inundate coastal areas, causing massive damage to the environment and human settlements.

Geographical Zones

• Anatolia
• Pacific Rim
• Coastlines
• Coastal Regions
• Western US Coastline
• Indonesia
• Southeast Asia Coastlines
• Japan
• Pacific Ocean
• Indian Ocean
• Caribbean
• Western coast of South America

Question 3

• Sea Level Rise: Global warming leads to melting glaciers and ice sheets, causing a rise in sea level. Coastal regions are increasingly at risk of inundation.
• Coastal Erosion: Increased storm surges contribute to more intensive coastal erosion.
• Salinization: Rising sea levels can introduce saltwater into freshwater systems, causing soil salinization.
• Habitat Loss: Coastal ecosystems and habitats are affected by sea-level changes, causing them to be lost.
• Ecosystems: Coastal habitats, such as mangrove forests and coral reefs, face habitat loss and damage.
• Economic Impacts: Coastal businesses, tourism, and infrastructure are harmed, leading to diverse economic impacts from saltwater intrusion to property damage and business losses.
• Human Migration: Coastal populations might migrate inland due to the impacts of rising sea levels.

Question 4

• Anthropocene: The current geological epoch where human impacts dominate the earth's ecosystems and environments.
• Driver of Change: Human activities, such as industrialization, deforestation, and emissions of greenhouse gases, impact the environment in several ways.
• Global Warming: Increases in greenhouse gas emissions are a key driver of rising global temperatures.
• Climate Change: Climate change disrupts natural systems and ecosystems, leading to significant environmental damage.
• Regional Impacts: Significant changes to the environment of different parts of the world.
• Biodiversity Loss: Human activities and climate change put enormous stress on Earth's biodiversity, resulting in substantial loss of plant and animal species that are vital to natural ecosystems.

Examples of Impacts

• Sea level rise: Coastal flooding and inundation events cause significant losses in coastal regions.
• Ocean acidification: Increased absorption of CO2 by the oceans causes the water to become more acidic.
• Changes in precipitation patterns: Alterations in precipitation negatively affect freshwater and agricultural systems.
• Species extinction: Human activities causing numerous species extinction events.
