Question

There are three basic layers in the earth interior when density and composition* are considered. What are these layers? [LO: 1] *Density essentially means how heavy. A high-density material like a piece of metal feels heavy when you pick it up. Composition here refers to the different types of minerals and rocks found within layers. lithosphere, asthenosphere, core mantle, asthenosphere, core crust, inner core, outer core crust, lithosphere, outer core crust, mantle, core The tectonic plates slide on top of which one of the following layers? [LO: 1/2] Ithosphere asthenosphere inner core mantle

Explanation / Answer

QUESTION 3: Answer: Crust, Mantle, Core. Explanation: These are three basic types of layers and they are subdivided into inner and outer core, lithosphere and asthenosphere to classify according to their properties. --------------------------------------------------------------------------------------------------------------------------------------- QUESTION 4: Answer: Asthenosphere. Explanation: The upper part of the mantle and the Earth's crust are called lithosphere and are made up of shapes like puzzle pieces. They are called tectonic plates.These tectonic plates move over a floating layer called asthenosphere. Due to its floating nature, this layer makes the plates to move.
