Answer (1)
PICK ONE1.Answer:Plate convergence causes two tectonic plates to move toward each other. When an oceanic plate converges with another oceanic or continental plate, the denser oceanic plate subducts beneath the lighter plate, forming deep ocean trenches and volcanic activity. When two continental plates converge, they collide and crumple, creating large mountain ranges such as the Himalayas. Thus, plate convergence directly forms features like trenches, volcanic arcs, and mountains.2. Answer:Convergent boundaries are zones of intense pressure and stress where plates collide or one subducts under another. This stress buildup can cause sudden releases of energy, resulting in earthquakes. Regions near trenches, subduction zones, and mountain ranges (e.g., Japan, Indonesia, the Himalayas) often experience frequent and sometimes powerful earthquakes due to this plate convergence.3.Answer:Oceanic-oceanic convergence forms volcanic island arcs and deep ocean trenches, affecting marine ecosystems.Oceanic-continental convergence creates coastal mountain ranges and volcanic arcs, influencing terrestrial ecosystems and human settlements.Continental-continental convergence produces massive mountain ranges and causes widespread crust deformation, affecting climate, habitats, and weather patterns. Each type leads to different hazards like earthquakes, tsunamis, and volcanic eruptions.4.Answer:Continuous plate convergence thickens and deforms the Earth's crust, building mountain ranges and deep ocean trenches over millions of years. It recycles oceanic crust via subduction, drives volcanic activity, and causes crustal uplift. Over geologic time, this shapes continents, changes sea levels, and impacts climate and ecosystems.5.Answer:Studying convergent boundaries allows scientists to identify regions prone to earthquakes, volcanic eruptions, and tsunamis. By understanding plate movements and stress accumulation, communities can develop early warning systems, improve building codes, and plan evacuation routes, thereby reducing the impact of natural disasters and saving lives.6. Answer:When one plate subducts under another, it sinks into the mantle where it melts due to high temperature and pressure. This melted material forms magma that rises to the surface, causing volcanic eruptions. The heat generated also creates geothermal activity, such as hot springs and geysers, especially near convergent boundaries with subduction zones.7.Answer:Scientists study rock formations, fossil records, and magnetic patterns at convergent boundaries to understand how continents moved over time. The presence of mountain ranges, volcanic arcs, and trenches reveals past collisions and subductions. This evidence helps reconstruct supercontinents like Pangaea and track Earth's tectonic evolution across millions of years.8.Answer:Predicting the outcomes of plate convergence is challenging because of the complex and variable nature of tectonic processes. Different regions have unique geological settings, plate compositions, and stress distributions that affect how plates interact. Factors like hidden faults, varying plate speeds, and unpredictable stress buildup make it difficult to forecast exactly when and where earthquakes, volcanic eruptions, or mountain formations will occur. Additionally, limited access to deep Earth data and the long timescales involved in tectonic movements add to the difficulty of precise predictions. These uncertainties pose challenges for disaster preparedness and risk assessment. PA BRAINLIEST PO PLS
