This animation uses real continent outlines, not abstract shapes, to show how Earth's single landmass Pangea—surrounded by the ocean Panthalassa—broke into Laurasia and Gondwanaland and then drifted apart into today's seven continents. Narrated in Chichewa, it first reverses present-day continents back to Pangea, then plays forward showing plate movement driven by mantle convection currents. It helps students connect continental drift and plate tectonics theory to familiar world map shapes rather than abstract models.

use this info to create animations that show how the land formations are formed in expanded and clear visuals. Explain in chichewa of Malawi. clearly show animation of drifts continets moving together and then to show how it all started in reverse then showing the drifts that led to the present continets. when showing plate techtonics use animation of a continet moving together or apart and not an abtract box without the continet showing. show formations from the continetnt picture not a model to help student understand so that it is connected to a place and not abstract.cotinental drift refers to the idea that earth’s continents have moved over geologic time relative to each other. This idea was propounded by a German scientist called Alfred Wegner. He proposed that the earth was once a single land mass called Pangea. And that this land mass was surrounded by a single super ocean called Panthalassa. However, the Pangea later split apart due to convectional currents within the upper part of the mantle. Pangea broke up to form two land masses namely Laurasia (Northern continent) and Gondwanaland (Southern continent). Continental theory is a theory that explains how the earth became divided into several continents that are there now.Plate tectonics is the theory that Earth's outer shell is divided into large slabs of solid rock, called “plates,” that glide over Earth's mantle, the rocky inner layer above Earth's core. Earth's solid outer layer, which includes the crust and the uppermost mantle, is called the lithosphere.Explanation: A tectonic plate (also called lithospheric plate) is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere. Plate size can vary greatly, from a few hundred to thousands of kilometers across; the Pacific and Antarctic Plates are among the largest. Plate thickness also varies greatly, ranging from less than 15 km for young oceanic lithosphere to about 200 km or more for ancient continental lithosphere (for example, the interior parts of North and South America). How do these massive slabs of solid rock float despite their tremendous weight? The answer lies in the composition of the rocks. Continental crust is composed of granitic rocks which are made up of relatively lightweight minerals such as quartz and feldspar. By contrast, oceanic crust is composed of basaltic rocks, which are much denser and heavier. The variations in plate thickness are nature's way of partly compensating for the imbalance in the weight and density of the two types of crust. Because continental rocks are much lighter, the crust under the continents is much thicker (as much as 100 km) whereas the crust under the oceans is generally only about 5 km thick. Like icebergs, only the tips of which are visible above water, continents have deep "roots" to support their elevations. Most of the boundaries between individual plates cannot be seen, because they are hidden beneath the oceans. Yet oceanic plate boundaries can be mapped accurately from outer space by measurements from GEOSAT satellites. Explanation: The theory of continental drift suggests that all the land masses on earth were once part of one supercontinent. Plate tectonics is the ability to measure the movement of land masses.
