Teach convection currents in the mantle
WebSep 12, 2024 · Convection currents are flowing fluid that is moving because there is a temperature or density difference within the material. Because particles within a solid are fixed in place, convection currents are seen only in gases and liquids. A temperature difference leads to an energy transfer from an area of higher energy to one of lower energy. WebYou can create your own convection current with water that will allow you to see the currents caused by the density difference of water at different temperatures. Supplies: ice cube tray water food coloring clear drinking glass or jar Procedure: Mix water and food coloring and pour the colored water into an ice cube tray.

WebIn this model, students will discover how convection currents in the Earth’s mantle cause tectonic movement. This activity is meant to be done as a teacher demonstration due to the use of very hot water. Grade Levels 6-8 Student Outcomes Students will: • Describe and model how convection currents cause tectonic plate motion. WebMantle convection is the very slow creeping motion of Earth's solid silicate mantle as convection currents carry heat from the interior to the planet's surface.. The Earth's surface lithosphere rides atop the asthenosphere and the two form the components of the upper mantle.The lithosphere is divided into a number of tectonic plates that are continuously …
WebApr 3, 2024 · The warm air at the equator rises and moves towards the poles. This causes the convection currents and cells that form global winds. In the ocean, cold (and salty) …
WebThe convection currents in the mantle are very similar to cooking a pot of soup. When a pot of soup is placed on a stove, the soup at the bottom of the pot is heated. As the soup warms up, it rises to the top of the pot. The cooler soup is more dense than the warm soup and begins to sink. This soup is then heated, and the process repeats. navy ced meaningWebThe first, and most common, theory is that the plates move due to convection currents in the Earth’s mantle.
