- Molten or partially molten rock that is found beneath the surface of the Earth.

- At the surface, magma is called lava.

Blocks of rocks falling into magma:

- When blocks of rocks fall into magma, they can cause several different things to happen, depending on the composition of the rock and the temperature of the magma.

Here are a few possible outcomes:

- Assimilation:

- The rock fragments may melt and be incorporated into the magma.

- This can happen if the rock is composed of minerals that are similar to those found in the magma, and if the temperature of the magma is high enough to melt the rock.

- Reaction:

- The rock fragments may react with the magma, forming new minerals.

- This can happen if the rock is composed of minerals that are not stable at the temperature and pressure of the magma.

- Quenching:

- The rock fragments may be rapidly cooled by the magma, forming a glassy texture.

- This can happen if the temperature of the magma is much higher than the melting point of the rock.

- Eruption:

- If the amount of rock fragments falling into the magma is large enough, it can cause the magma to erupt.

- This is because the addition of rock fragments can increase the volume of the magma and make it more buoyant.
