Humans have had a lot of influence on their surroundings in Africa and the Middle East, from causing deforestation to hunting out entire species of animals. This is caused by the natural moments of the plates as they glide on the semi-liquid mantle. The slow circulation of rock in the mantle moves the tectonic plates at the surface. Scientist have long been studying tectonic plate movement and its causes. Where convection currents diverge near the Earth's crust, plates move apart. The theory that scientists have developed to explain how tectonic plates move is called the theory of plate tectonics. Before explaining what causes the tectonic plates move, let’s get some idea about what are tectonic plates. However, convection also drives plate tectonics. 8 years ago. Areas in which the lower layers of the mantle are broken and subjected to greater heat intensity (observed by the presence of volcanoes, hot springs, or cracks in or between plates) move more rapidly because the convection of more heat is causing the asthenosphere to expand more quickly. This is mostly true. When trying to understand how the convection currents cause the tectonic plates to move, it may help to visualize a conveyor belt at a grocery store.
Convection keeps the plates thin enough to move.

In this lesson, we will examine the settings from the fairytale 'Rapunzel' by the Brothers Grimm. The global distribution of earthquakes is similar to that of volcanoes. Replies. Describe the idea of plate tectonics. ( 3 ) 9. How does mantle convection drive plate tectonics? The tectonic plates, or the lithosphere, lies on top of the mantle and seems to float on it. We will also introduce the concept of volcanism at mid-ocean ridges. Oceanic crust only. Crustal movements might cause separation in the land. How do convection currents cause tectonic plates to move? Effects of Electromagnetic Radiation on Living Cells. A tectonic plate is a large slab of solid rock with an irregular shape that is made up of the oceanic and continental lithosphere. This allows the plates to "float" on top of the denser material. Tectonic plates on the crust move. Eventually, through convection currents, the magma rises to the earth surface, forming volcanoes on the folded continental plate. Plates at the surface of the Earth move due to intense heat from the core of the planet. 0% average accuracy. Convection makes the plates solid enough to move. Educators go through a rigorous application process, and every answer they submit is reviewed by our in-house editorial team. As the cooled material sinks down, it is warmed and rises again. Another way that volcanoes can erupt is by a "HOTSPOT". Earn Transferable Credit & Get your Degree, Get access to this video and our entire Q&A library. Tectonic plates move in different directions. When it sinks down, it breaks it apart (compressional force). As the rock underlying the tectonic plates moves in response to the heat being transmitted by convection from the Earth's core, the tectonic plates are also moved. For instance, some geologists believe that the main factor for the motion of plate tectonics is convection currents that occurs in the mantle. eNotes.com will help you with any book or any question. What is Plate Tectonics? The size of the plate varies to a large extent, ranging from a few hundred to thousands of kilometers. ', Why is the interior of the earth very hot? In this lesson, we'll discuss ridge-push, which is one of the driving forces behind tectonic plate motions. As liquid rock cools, it goes downward. Inside the Earth, convection is powered by heat mostly from the core.
