which of the following shows the structure of earth in the correct order from innermost to outermost layer
The correct order from innermost to outermost layer of the Earth is:
1. Inner Core
2. Outer Core
3. Mantle
4. Crust
The correct order of Earth's structure, from innermost to outermost layer, is as follows:
1. Inner core - This is the innermost region of the Earth, consisting mainly of solid iron and nickel. It is estimated to have a radius of about 1,220 kilometers.
2. Outer core - Surrounding the inner core, the outer core is a layer of liquid iron and nickel that extends to a radius of approximately 3,400 kilometers.
3. Mantle - The mantle is the thickest layer of Earth, extending from the bottom of the crust to around 2,900 kilometers deep. It consists of solid rock, but due to intense pressure and high temperatures, it can flow slowly over long periods of time.
4. Crust - The Earth's crust is the outermost layer, which includes both the continental and oceanic crusts. The continental crust is thicker (average of around 30-50 kilometers) and less dense compared to the oceanic crust (approximately 5-10 kilometers thick). The crust is made up of several different types of rock, including granite, basalt, and sedimentary rocks.
So, the correct order is: Inner core, Outer core, Mantle, Crust.
