What are the key differences between convergent, divergent, and transform plate boundaries?<\/strong><\/p>\n<ul>\n<li><strong>Convergent:<\/strong> Plates collide, resulting in mountain ranges, volcanoes, and earthquakes.<\/li>\n<li><strong>Divergent:<\/strong> Plates move apart, creating new crust, rift valleys, and mid-ocean ridges.<\/li>\n<li><strong>Transform:<\/strong> Plates slide past each other horizontally, causing earthquakes along fault lines.<\/li>\n<\/ul>\n<p><strong>2. How does the rock cycle work?<\/strong><\/p>\n<p>The rock cycle is a continuous process where rocks transform from one type to another through weathering, erosion, deposition, heat, and pressure. Igneous rocks form from cooling magma, sedimentary rocks form from sediments, and metamorphic rocks form when existing rocks are transformed by heat and pressure.<\/p>\n<p><strong>3. What are the major types of aquifers and their characteristics?<\/strong><\/p>\n<ul>\n<li><strong>Unconfined aquifers:<\/strong> Open to the surface, easily recharged by rainfall.<\/li>\n<li><strong>Confined aquifers:<\/strong> Bounded by impermeable layers, less susceptible to contamination.<\/li>\n<li><strong>Perched aquifers:<\/strong> Occur above the main water table, often temporary and smaller.<\/li>\n<\/ul>\n<p><strong>4.
