The correct answer is mantle.
The layer of Earth that is best characterized as a layer of soft, hot rock is the mantle.
To answer this question, we need to understand the different layers of the Earth and their characteristics.
The Earth has four main layers: the crust, the mantle, the outer core, and the inner core.
The crust is the outermost layer of the Earth and is made up of solid rock. It is relatively thin compared to the other layers.
The mantle is located beneath the crust and is made up of semi-molten rock. It is characterized as being soft and hot. The heat in the mantle comes from the Earth's interior and causes the rocks to be partially melted.
The outer core is located beneath the mantle and is primarily composed of liquid iron and nickel. It is even hotter than the mantle, but it is not characterized as soft. The high temperature allows the outer core to remain in a liquid state.
The inner core is located at the center of the Earth and is primarily composed of solid iron and nickel. It is the hottest and the most dense layer of the Earth.
Now, to answer the question, the layer of Earth that is best characterized as a layer of soft, hot rock is the mantle. Therefore, the correct response is "mantle".
