INSIDE THE EARTH taught thousands of kids about Earths crust, mantle, and core. MAGIC SCHOOL BUS PRESENTS PLANET EARTH will expand upon the original title with fresh, updated Common Core-aligned content about all the wonders of our planet. With vivid full-color photographs on each page and illustrations of the beloved Ms. Frizzle and her students, the Magic School Bus Presents series will enthrall a whole new generation of Magic School Bus readers.
6 Fascinating Facts About the Earth's Mantle
The mantle is the thick layer of hot, solid rock between the Earth's crust and the molten iron core. It makes up the bulk of the Earth, accounting for two-thirds of the planet's mass. The mantle starts about 30 kilometers down and is about 2, kilometers thick. Earth has the same recipe of elements as the Sun and the other planets ignoring hydrogen and helium, which have escaped Earth's gravity. Subtracting the iron in the core, we can calculate that the mantle is a mix of magnesium, silicon, iron, and oxygen that roughly matches the composition of garnet. But exactly what mix of minerals is present at a given depth is an intricate question that is not firmly settled. It helps that we have samples from the mantle, chunks of rock carried up in certain volcanic eruptions, from depths like kilometers and beyond.
The silicate rock is the main component of mantle of earth. Actually this material is also found in Mars, Europa, lo, Moon and Vesta. There are several layers which make up the interior of earth. During the geological time, the mantle was in viscous fluid. Now it is mostly in solid texture. It is very hot and contains high amount of nickel and iron.
Then, why not take a look at the activities to support your learning in the section at the end to test what you have learned? The Earth is made of three layers that are just like an onion., But it is made up of different layers, a bit like an onion.
The Earths mantle lies between the crust and the outer core of our planet. It is a rocky shell similar to Mercury, Venus and Mars. The mantle is 2, km 1, mi thick. The mantle is divided into the upper and lower mantle. The upper mantle starts at the Moho boundary. This boundary was discovered by the Croatian seismologist, Andrija Mohorovicic. Earthquake waves travel at a slower speed prior to reaching this boundary.
