Question

what creates lava and how does lava become molded

Answer 1

Lava is molten rock. It is created deep beneath Earth's surface (often 100 miles or more underground), where temperatures get hot enough to melt rock. Scientists call this molten rock magma when it's underground.Lava is molten rock.

Answer 2

It is created deep beneath Earth's surface  where temperatures get hot enough to melt rock.
Eventually, some magma makes its way to Earth's surface and escapes via a volcanic eruption. When magma erupts onto Earth's surface and begins to flow, scientists then call it lava.
