SCI

• Divergent - move away from one another (trenches, ridges/rifts, volcanoes)
• Convergent - collide or moves toward one another (mountains, volcanoes, mountain ranges, subduction zones)
• Transform - slides or pass through one another (no landforms are formed)
• Geologists estimated that there are 100,000 active and inactive volcanoes on Earth.
• Active Volcanoes are located in two volcanic belts: Alpine-Himalayan Belt and Circum-Pacific Belt.
• Reveals the collision of the African and Indo-Australian plate with the southern margin of the Eurasian plate.
• CIRCUM-PACIFIC BELT- Home for the world’s active volcanoes including in New Zealand, Philippines, New Guinea, Japan, the Kamchatka Peninsula of Russia, Alaska, the western region of the United States, Central America, the western region of South America, and the numerous volcanic Pacific islands scattered between these lands.
• Mountain Ranges - One of the landforms made by the convergent boundaries
• TECTONIC PLATES - Are huge and irregularly shaped rocks/solid rocks composed of both continental and oceanic lithosphere
• PANGEA - Super Continent
• MOHOROVICIC DISCONTINUITY - The boundary between the crust and the mantle.
• MOHOROVICIC DISCONTINUITY- The boundary between the crust and the mantle.
• MOHOROVICIC DISCONTINUITY - Discovered in 1909 by Andrija Mohorovicic.
• MOHOROVICIC DISCONTINUITY - Discovered in 1909 by Andrija Mohorovicic.
• MOHOROVICIC DISCONTINUITY - 8 km beneath ocean basins. 32 km beneath continental surfaces
• MOHOROVICIC DISCONTINUITY - It is like an imaginary line or area, it is not a part of the earth.
• Crust - Outermost layer and thinnest layer
• Crust - Composed of continental and oceanic crust
• Crust - Consist of dark, dense, basalt
• Crust - Consist of dark, dense, basalt
• Crust - Composed of continental and oceanic crust
• Mantle - Thickness of almost 2900 km
• Mantle - Thickness of almost 2900 km
• Upper Mantle - Made up of rocks rich in Mg and Fe but poor in silica
• Upper Mantle - 400 km thick and much denser than rock
• Upper Mantle - Compromises 10% of the earth’s mass
• Upper Mantle - Compromises 10% of the earth’s mass
• Upper Mantle - 400 km thick and much denser than rock
• Asthenosphere - upper part of the mantle
• Asthenosphere - It is part liquid and solid rocks/structure since the magma is here
• Outer Core - 2100 km thick, liquid
• Inner Core - 1300 km thick, solid
• Core - Made up of mostly Fe and Ni
• Inner Core - 1300 km thick, solid
• Outer Core - 2100 km thick, liquid
• Core - Made up of mostly Fe and Ni
• Alfred Wegener - Alfred Lothar Wegener
• Alfred Wegener - German meteorologist and geophysicist
• Alfred Wegener - Formulated the first complete statement of the Continental Drift hypothesis
