What is the correct order (starting from the surface) of Earth’s layers?
1 point
mantle, inner core, crust, outer core,Option 1
Mantle, outer core, Inner core, crust,
Crust, mantle, outer core, inner core
Outer core, inner core, crust, mantle
Crust, mantle, outer core, inner core
The correct order of Earth's layers, starting from the surface, is:
1. Crust
2. Mantle
3. Outer core
4. Inner core
Therefore, option 3 - Crust, mantle, outer core, inner core - is the correct answer.
To determine the correct order of Earth's layers, you can refer to the structure of the Earth. The Earth is composed of several layers, including the crust, mantle, outer core, and inner core.
1. Crust: The Earth's crust is the outermost layer and consists of solid rocks and minerals. It is relatively thin compared to the other layers and is divided into two main types: continental crust (found under landmasses) and oceanic crust (found under oceans).
2. Mantle: The mantle is the layer that lies beneath the crust. It is much thicker than the crust and consists of semi-solid rock. The mantle is further divided into two parts: the upper mantle and the lower mantle.
3. Outer Core: The outer core is located beneath the mantle and is composed of liquid iron and nickel. It surrounds the inner core and plays a crucial role in generating Earth's magnetic field.
4. Inner Core: The inner core is the innermost layer and is primarily composed of solid iron and nickel. It is under immense pressure and temperature, causing it to be in a solid state even though it is at the Earth's center.
Based on this information, the correct order of Earth's layers, starting from the surface, is: crust, mantle, outer core, inner core. So, the correct option in this case is "Crust, mantle, outer core, inner core."
