Which of these best describes the asthenosphere inside of the earth's mantle? it not quite liquid or solid, similar in texture to toothpaste it is molten liquid metal it is solid due the extreme pressure of the earth's other layers smashing down on it it is a firm, rocky outer layer

The "asthenosphere" inside of the "earth's mantle" is "not quite liquid or solid, it is similar in texture to toothpaste".

Explanation:

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".
