Put the 3 main layers of Earth in order from outermost (top) to innermost (bottom)
The correct order of the three main layers of Earth from the outermost to innermost is:
1. Crust
2. Mantle
3. Core
The three main layers of Earth, in order from outermost (top) to innermost (bottom), are:
1. Crust: The Earth's outermost layer is called the crust. It is relatively thin compared to the other layers and is made up of solid rock. There are two types of crust: continental crust, which underlies the land masses, and oceanic crust, which is found beneath the oceans.
2. Mantle: The mantle lies beneath the crust and is the largest layer of Earth. It consists of hot, solid rock that is capable of flowing slowly over long periods of time. The uppermost part of the mantle is known as the asthenosphere, which has a partially molten and plastic-like quality.
3. Core: The core is the innermost layer of Earth and is composed of two parts: the outer core and the inner core. The outer core is primarily made of liquid iron and nickel and is responsible for generating Earth's magnetic field. The inner core, in contrast, is solid and is believed to be made up of solid iron and nickel.
To put the three main layers of the Earth in order from outermost (top) to innermost (bottom), you should follow these steps:
1. Identify the layers: The three main layers of the Earth are the crust, mantle, and core.
2. Determine the positioning: Each layer has different properties and compositions, which allows us to distinguish them and place them in the correct order.
3. Start with the outermost layer: The crust is the Earth's outermost layer, so it will be the first layer in our order.
4. Move to the middle layer: The mantle lies beneath the crust and constitutes the bulk of the Earth's volume. Therefore, it will be the second layer in our order.
5. Reach the innermost layer: The Earth's core is the central part and lies beneath the mantle. It is divided into two regions, the outer core and the inner core. The outer core, being closer to the mantle, will be the third layer in our order, and the inner core, located at the very center, will be the last layer.
Therefore, the correct order from the outermost (top) to the innermost (bottom) layer of the Earth is:
1. Crust
2. Mantle
3. Outer core
4. Inner core.
