The layer which does not transmit the S-waves is _______

Internal Structure of the Earth contains the crust, mantle and core. The Earth's internal structure is made up of four main layers: Inner core: A solid sphere made of iron and nickel metals, about 759 miles (1,221 kilometers) in radius. Outer core: Made of nickel, iron, and molten rock, temperatures here can reach up to 50,000 C. Mantle: Mostly solid rocks and minerals, but punctuated by malleable areas of semi-solid magma.

Internal Structure of the Earth contains the crust, mantle and core.

The Earth's internal structure is made up of four main layers:
Inner core: A solid sphere made of iron and nickel metals, about 759 miles (1,221 kilometers) in radius.
Outer core: Made of nickel, iron, and molten rock, temperatures here can reach up to 50,000 C.
Mantle: Mostly solid rocks and minerals, but punctuated by malleable areas of semi-solid magma.
Crust: The outside layer of the Earth, made of solid rock, mostly basalt and granite. 

Each layer has a unique chemical composition and physical state, and can impact life on Earth's surface. 
The Earth's basic structure—crust, mantle, and core—appears to be replicated on the other terrestrial planets.
