The most dense layers of the Earth are at __ the surface C the middle portion the center

## Step 1<br />The Earth is structured in layers, each with distinct properties. From the outermost to the innermost, these layers are the crust, mantle, outer core, and inner core.<br /><br />## Step 2<br />The crust is the outermost layer, which is solid and relatively thin.<br /><br />## Step 3<br />The mantle is beneath the crust and is much thicker. It is also solid but can flow over long periods of time.<br /><br />## Step 4<br />The outer core is beneath the mantle and is liquid.<br /><br />## Step 5<br />The inner core is at the center of the Earth and is solid. It is the densest layer of the Earth.<br /><br />## Step 6<br />The density of the Earth's layers increases as you move towards the center. This is due to the immense pressure exerted on the inner layers from the weight of the overlying layers.<br /><br />## Step 7<br />The inner core is composed mainly of iron and nickel and is in a solid state due to the immense pressure, despite the high temperature.
