If anything is rock-solid, it will result in a flat landscape. This will mean that there will be no plateaus, deep sea trenches, volcanoes or mountains if the mantle were solid rock.
If the mantle were solid rock, features such as volcanic islands, mid-ocean ridges, and subduction zones would not form on Earth's surface. The movement and interaction of semi-solid rock within the mantle are essential for the processes of plate tectonics and volcanic activity that shape the planet's surface.
If you were 100 km below the surface you would be in the upper mantle / asthenosphere.
can you answer my question today 22 abril
The avocado's flesh would best represent the Earth's mantle in this analogy. Just like the mantle is the thickest layer beneath Earth's crust, the flesh is the thickest part of the avocado surrounding the pit. Both the mantle and avocado flesh occupy a substantial portion of their respective structures.
The star with a surface temperature closest to the boundary between Earth's mantle and core would be the Sun, with a surface temperature of about 5,500 degrees Celsius. The temperature at the boundary between Earth's mantle and core is estimated to be around 3,000-4,000 degrees Celsius.
I would call this convection currents in the mantle.
you will find it in earths mantle because it is a kind of an igneous rock
That depends where it is. On the surface of the planet it would be lava and in the earths core it would be the mantle.

If it were molten, it would be called magma.

They'd stop moving.
They will stop.
That would be latitude or longitude.
