Grimsvotn is a stratovolcano, which is a tall, conical volcano composed of layers of hardened lava, tephra, and volcanic ash. It is located in Iceland and is one of the most active volcanoes in the country.

Without seeing diagram A, I can provide a general description of a common type of volcano, the stratovolcano. Stratovolcanoes, or composite volcanoes, are characterized by their steep, conical shape and are formed through the alternating eruption of lava flows and explosive ash and tephra deposits. This process occurs at convergent plate boundaries, where an oceanic plate subducts beneath a continental plate, leading to the melting of mantle materials and the subsequent eruption of magma. Over time, these layers build up, creating the volcano's distinctive profile.
The various types of material ejected by a volcano are called volcanic products, which can include ash, lava flows, pyroclastic flows, volcanic gases, and volcanic bombs. These materials vary in size, composition, and behavior depending on the type of volcano and the eruption style.

Cinder Cone Volcano
Volcanoes form when magma (liquid rock inside the earth) reaches the surface. Depending on the type and duration of the eruption lava and or tephra can pile up to make a volcano
The type of eruption that a composite volcano has is lava flow with cinders and bombs in an explosive eruption

A shield volcano forms when layers of basaltic lava accumulate during a nonexplosive eruption. These volcanoes have gentle sloping sides and are usually characterized by their broad and flat shapes. Mauna Loa in Hawaii is a well-known example of a shield volcano.
