the half-cooked egg yolk oozes out only when it is still hot. In the same manner, the magma on the mantle also rises because of high temperature, in the mantle, or the crust?

the mantle

Explanation:

The correct answer would be the mantle.

The magma is a hot, molten fluid or semi-fluid located beneath the earth's surface and capable of finding its way through fissures into the surface of the earth in a process known as a volcanic eruption.

From the innermost to the outermost, the earth layer consists of the inner core, the core, the mantle, and the crust. More specifically, the magma is known to originate from the lower part of the crust and the upper part of the mantle. The mantle's temperature is high and forms a layer of partially molten rock.
