The "asthenosphere" inside of the "earth's mantle" is "not quite liquid or solid, it is similar in texture to toothpaste".
<u>Explanation:</u>
The "asthenosphere" is the uppermost layer of the "Earth's mantle". This layer in the Earth's interior is said to be responsible for convection. It is mostly comprised up of a mixture of magma which is in molten state and solid Earth material.
The convection currents which occurs in the asthenosphere are responsible for the "tectonic movement of Earth's surface plates".
