The mantle
The mantle is the hot rock.
Not exactly--the mantle is comprised of semisolid rock, or magma.
The layer of the Earth that is hot and semi-solid is the mantle. The mantle is located between the Earth's crust and core and is made up of molten rock, called magma, that circulates due to heat convection from the Earth's core.
The outer core.
C.) the thickest layer of hot rock
No, the inner part of the Earth's crust is not hot melted rock. The inner core of the Earth is made up of solid iron and nickel, while the outer core is composed of liquid iron and nickel. The hot melted rock is found in the mantle layer beneath the crust.
the mantle
The semi-solid layer of the Earth is called the mantle. It lies between the Earth's crust and core and is composed of hot, flowing rock.
Clay, typically, is the only soft and plastic rock. Unless you were thinking of the Mantle, which forms the bulk of the planet Earth. It is hot enough to be "molten" although in fact is extremely viscous.
The layers of the Earth by their physical composition are: Crust - the outermost layer made of solid rock and soil Mantle - composed of hot molten rock called magma Outer core - a liquid layer made of iron and nickel Inner core - a solid layer comprised of iron and nickel.
The layer of Earth made of hot, dense rock is called the mantle. It lies between the Earth's crust and the outer core, extending to a depth of about 2,900 kilometers (1,800 miles). The mantle is composed of silicate minerals and is capable of slow, convective flow, which drives plate tectonics. Its temperature ranges from approximately 500 to 4,000 degrees Celsius (932 to 7,232 degrees Fahrenheit).
The three main parts of the Earth are the crust (outer layer), mantle (middle layer), and core (innermost layer). The crust is where we live and is divided into tectonic plates, the mantle is made of hot rock that flows slowly, and the core is composed of mostly iron and nickel.
