True. Many eruptions produce massive clouds of ash, gas, and pumice rather than lava. Phreatic eruptions, as another example, are essentially steam explosions.
Magma is not an eruption. Magma is a mixture of molten minerals and dissolved gas that is underground. All volcanic eruptions, apart from phreatic eruptions, involve magma.

Magma that is ejected during a volcanic eruption forms extrusive igneous rocks. They are also referred to as volcanic rocks.
yes
Phreatic eruptions occur when water comes into contact with magma, causing a steam-driven explosion. Phreatomagmatic eruptions involve the interaction of water and magma to produce explosive eruptions. Surtseyan eruptions refer to shallow submarine or coastal volcanic eruptions that interact with water or ice, creating explosive activity.

This is known as a volcanic eruption.
The composition of the magma affects how explosive a volcanic eruption will be.

The more gases, water vapor and silica there is in magma the bigger the explosiveness of a volcanic eruption.
