The layer of Earth that is best characterized as a layer of soft, hot rock is the mantle.
The layer of Earth that is best characterized as a layer of soft, hot rock is the mantle. To arrive at this answer, we can look at the basic structure of the Earth. There are three main layers - the crust, mantle, and core.
The crust is the outermost layer and is relatively thin compared to the other two layers. It is made up of solid rock, including both continental crust (under land) and oceanic crust (under the ocean).
Beneath the crust lies the mantle, which is much thicker. The mantle is composed of semi-soft rock that is heated by the intense heat from the Earth's core. The temperature and pressure in the mantle cause the rock to become soft and malleable, although it is not liquid like the outer core.
The outer core, just below the mantle, is a layer of liquid molten metal, mainly iron and nickel. It is responsible for generating the Earth's magnetic field.
Lastly, the inner core is the innermost layer of the Earth. It is solid and made up of hot, dense metals due to extreme pressure. However, it is not soft like the mantle.
Therefore, the layer of soft, hot rock is the mantle.
