No. The Earth's core is divided into two parts: a solid inner core and a liquid outer core, moth made mostly of iron.
Earth's crust is very hard because it is made of rock. If it wasn't hard you would sink down into the Earth's core.
The core
No. As the word "core" might imply, it is the innermost part of Earth. The outermost layer is the crust.
its called the mantle
The Earth's core is not made up of rocks. It is made up primarily of nickel and iron.

the layer in the earths suface that contains liquid rock is called: the inner core (mainly)\ outer core (some) and (parts) of the mantle.

hard rock
Any rock mostly igneous rocks but in their molten state, because the inner core has a too high temperature.
