what are the layers of the earth's interior in order??? Please send asap I am making a science study guide for my huge exam!
Im pretty sure its outer crust, inner crust, mantle, and core. Again, im only pretty sure. I don't have my science text book with me.
Here's a diagram.

Sure, I can help you with that! The Earth's interior can be divided into three main layers: the crust, the mantle, and the core. Here is the order of the layers, starting from the surface:
1. Crust: The Earth's crust is the outermost layer and is divided into two types: the continental crust and the oceanic crust. The continental crust is thicker and less dense than the oceanic crust. It is primarily composed of various types of rocks like granite and is found beneath landmasses. The oceanic crust is thinner and denser, consisting mainly of basalt, and is found beneath the oceans.
2. Mantle: Below the crust lies the mantle, which is the thickest layer of the Earth. It extends from the base of the crust to about 2,900 kilometers (1,800 miles) deep. The mantle is made up of solid but malleable rock materials, such as silicate minerals rich in iron and magnesium. It can be further divided into the upper mantle and the lower mantle based on their physical properties.
3. Core: At the center of the Earth is the core, which is divided into two parts: the outer core and the inner core. The outer core, about 2,300 kilometers (1,400 miles) thick, is mainly composed of liquid iron and nickel. It plays a crucial role in generating the Earth's magnetic field. The inner core, on the other hand, is solid and consists primarily of solid iron and nickel due to intense pressure at the center of the Earth.
Remember, the core is at the center, the mantle surrounds the core, and the crust is the outermost layer.
For your study guide, it might be helpful to include some key characteristics, composition, and thickness of each layer to have a comprehensive understanding of the Earth's interior. Good luck on your exam!
