The discovery of rift zones also led to the Theory of Plate Tectonics. It is estimated that along Earth's mid-ocean ridges every year 2.7 km 2 (1.0 sq mi) of new seafloor is formed by this process. Rift valley. The Himalayan _____ range was formed from the collision of the Indian continental plate colliding into the Eurasian continental plate. Plate tectonics is a unifying theory; it explains nearly all of the major geologic processes on Earth. The lithosphere overlies a softer layer of molten rock called the asthenosphere. Tectonic plates are pieces of Earth's crust and uppermost mantle, together referred to as the lithosphere. The theory that the earth's crust is divided into plates that move. The theory, which solidified in the 1960s, transformed the earth sciences by explaining many phenomena, including mountain building events, … Plate Tectonics - Formidable Forces.

Plate tectonics definition, a theory of global tectonics in which the lithosphere is divided into a number of crustal plates, each of which moves on the plastic asthenosphere more or less independently to collide with, slide under, or move past adjacent plates. Homework . Mid-Atlantic Ridge. Solo Practice. The plates’ edges can be drawn by connecting the dots that mark earthquakes’ epicenters. 8th grade . As these plates move over the Earth’s fluid mantle, they interact with each other, forming plate boundaries or zones. convergent boundary. The site has a glossary to help students with vocabulary. If a plate with oceanic lithosphere meets another plate, the dense oceanic lithosphere dives beneath the other plate and sinks into the mantle. 1 Answer. by p_gaebler_71637. Finish Editing. Edit. This is a list of tectonic plates on Earth's surface. The sinking oceanic lithosphere drags the rest of the tectonic plate and this is the main cause of plate motion. PLAY. Plate tectonics is the fundamental mechanism that drives geological processes in the geosphere. Plate tectonics involves the formation, lateral movement, interaction, and destruction of the lithospheric plates. Created by. Mid-Ocean Ridge. To play this quiz, please finish editing it. Tectonic basins and rift valleys, landforms characterized by relatively steep, mountainous sides and flat floors. The continents are still moving today. In simple terms, a rift can be thought of as a fracture in the earth's surface that widens over time, or more technically, as an elongate basin bounded by opposed steeply dipping normal faults. Save. The steep sides are created by displacement on faults such that the valley floor moves down relative to the surrounding margins, or, conversely, the margins move up relative to the Plate tectonic theory is based on an understanding of the Earth's internal structure, the different types of tectonic plates and plate boundaries, and the driving forces of plate movements. The _____-_____ _____ is an example of a divergent boundary. Science. Map showing plate boundaries where Great Rift Valley is splitting African continent in Kenya. ). Much of Earth's internal heat is relieved through this process and many of Earth's large structural and topographic features are consequently formed. 69% average accuracy. Granitic. But every now and again something dramatic happens and leads to renewed questions about the African continent splitting in two. Plate tectonics. Test. You can see how it fits like a puzzle piece just southwest of Madagascar, which also shows you the direction that the plate is moving. Plate tectonics was a suitable explanation for seafloor spreading, and the acceptance of plate tectonics by the majority of geologists resulted in a major paradigm shift in geological thinking. In this 3D lesson plan, learn about the general distribution of fold mountains, volcanoes, and earthquakes, and how their distribution is related to movements at plate boundaries Grades: 7 th, 8 th, 9 th, 10 th. Print; Share; Edit; Delete; Host a game. Movement of the plates over Earth’s surface is termed plate tectonics. a large rift usually remains and is never filled in most likely the country of Mexico will separate from the continental United States volcanoes can occur scientists expect entire continents to fall into the Earth Plate tectonics is a scientific theory describing the large-scale motion of seven large plates and the movements of a larger number of smaller plates of the Earth’s lithosphere, since tectonic processes began on Earth between 3 and 3.5 billion years ago. The discovery of rift zones led to the understanding of how continental drift could occur on our planet that had been proposed by Alfred Wegener earlier in the 20th Century. Match. oceanic plates/crust made up of basalt. Tectonics embraces as its chief working principle the concept of plate tectonics (q.v. Some of the most dynamic sites of tectonic activity are seafloor spreading zones and giant rift valleys. Plate tectonics is a good example of this. Spell. The main driving force of plate tectonics is gravity. This bundle contains all your teaching needs for a plate tectonics unit & You save money! My favorite way to use this is to give each group of students a whiteboard to . The plates are always moving and interacting in a process called plate tectonics. Whether it be how directional changes in extension may affect rift linkage and microplate development (Zwaan et al., 2016), or examining the effect of melting processes on suspected microplates in magmatically active regions (e.g. a divergent plate boundary on continental crust. What is number nine? The lithosphere is broken up into about a dozen large plates and several small ones. M. Klose, Content Writer Answered: Aug 29, 2018. Plate tectonics probably began at a global scale during the Mesoarchean (c. 2.9–3.0 Ga), with firm evidence for subduction in older geological terranes accounted for by isolated plate tectonic ‘microcells’ that initiated at the heads of mantle plumes. At a _____ plate boundary new crust is created as two or more plates pull away from each other. If the process continues long enough and the continental crust is effectively separated, the continental rift … Oceans _____ can be created or grow wider where plates diverge or pull apart. SURVEY . According to the theory, Earth has a rigid outer layer, known as the lithosphere, which is typically about 60 miles (100 kilometers) thick. Edit. Learn. The model builds on the concept of continental drift, an idea developed during the first decades of the 20th century. Key Concepts: Terms in this set (45) divergent . oceanic plates/crust made up of granite. Plate tectonics map from NASA. transform boundary. Played 136 times. Although many studies have examined plate boundary dynamics and rift linkage, there is so much complexity left to investigate. Plate Tectonics DRAFT. oceanic ridges.

Note that the island of Madagascar split off from the African continent about 65 million years ago. answer choices . The East African Rift System (EARS) is one the geologic wonders of the world, a place where the earth's tectonic forces are presently trying to create new plates by splitting apart old ones. Since its early inception in the 1950s and 1960s, geologists have been guided by this revolutionary perception of the world. See more.
