3. In the following table, location examples are given for each type of plate boundary. For eac describe the type of plate boundary, indicate the motions involved (draw or describe), and list any associated hazards. Give another location in the world where this type of boundary is foun h location, Location of plate Type of plate Description of boundary boundary movement San Andreas fault Associated hazards Another location where found Mid-Atlantic ridge East African rift (Great Rift Valley) India/Nepal border SW Coast of British Columbia Japan

Explanation / Answer

Location of plate boundary Types of plate boundary Description of movement Associated hazards Another location where found San andreas fault movement Continental transform fault between the Pacific Plate and the North American Plate Its motion is right-lateral strike-slip (horizontal) Divides into three segments, each with different characteristics and a different degree of earthquake risk. Fault extended all the way into southern California. It slices California in two from Cape Mendocino to the Mexican border. San Diego, Los Angeles and Big Sur are on the Pacific Plate. Mid-Atlantic Ridge (MAR) A mid-ocean ridge, a divergent tectonic plate or constructive plate boundary In the North Atlantic it separates the Eurasian and North American Plates, and in the South Atlantic it separates the African and South American Plates. Tectonic plates, where magma from the mantle reaches the seafloor, erupting as lava and producing new crustal material for the plates The island of Iceland is also known as the Reykjanes Ridge. East African Rift (EAR) Active continental rift zone in East Africa, developing divergent tectonic plate boundary The African Plate is in the process of splitting into two tectonic plates, called the Somali Plate and the Nubian Plate, at a rate of 6–7 mm annually Erupting lava and producing new crustal material for the plates Includes the Main Ethiopian Rift, running eastward from the Afar Triple Junction, which continues south as the Kenyan Rift Valley India-Nepal border Continent-continent collision tectonics Collision of Indian subcontinent and Eurasia at the Paleocene/Eocene epoch Earhquake The northernmost Range of mountains are the Karakoram Mountains that continue into Pakistan and China. Sw coast of British Columbia Fracture and collapse forming mountain ranges in a process called orogeny, rifting The Coast Belt is the suture zone between the Intermontaine Belt and the Insular Belt and is composed of plutonic and metamorphic rock Volcanic and earthquake activity take place The Rocky Mountain Fault and the San Juan Fault Japan Subduction zone or convergent plate boundary The islands of Japan are primarily the result of  the subduction of the Philippine Sea Plate beneath the continental Amurian Plate and Okinawa Plate to the south, and subduction of the Pacific Plate under the Okhotsk Plate to the north Japan is situated in a volcanic zone on the Pacific Ring of Fire. Frequent low intensity earth tremors and occasional volcanic activity are felt throughout the islands. Japan was originally attached to the eastern coast of the Eurasian continent. The subducting plates, being deeper than the Eurasian plate, pulled Japan eastward, opening the Sea of Japan, Strait of Tartary and the Korea Strait
