Dome complexes typically erupt andesite to rhyolite magma, which is characterized by high viscosity. This viscosity leads to the formation of steep-sided volcanic domes, as the magma doesn't flow easily and tends to pile up near the vent. The eruptions can be explosive due to the buildup of gas pressure within the viscous magma. Consequently, dome complexes often exhibit both dome-building eruptions and pyroclastic flows.

What type of magma erupts out of dome complexes?
Viscous and silica-rich magma, such as dacite or rhyolite, often erupts out of dome complexes. Due to its high viscosity, this type of magma tends to form domes and does not flow as easily as basaltic magma.
How a dome mountain can eventually form out of magma that are hardened beneath earth's surface?
A dome mountains forms when rising magma is blocked by horizontal layers of rock. The magma forces the layers of rock to bend upward into a dome shape. Eventually, the rock above the dome mountain wears away, living it exposed.
A forms when magma slowly rises up inside the crater of a larger volcano.?
When magma slowly rises up the inside the crater of a larger volcano, it forms a Lava Dome.
Describe how a dome mountain can eventually form out of magma that hardened beneath earths surface?
A dome mountain forms when magma is injected into the Earth's crust and starts to push upward, creating a bulge or dome shape. As the magma cools and solidifies beneath the surface, it forms a layer of hardened rock. Over time, erosion gradually removes the overlying layers, exposing the dome-shaped mountain.
When magma re-enters a magma chamber causing the floor of the caldera or crater to lift the resulting structure is called a?
Resurgent dome is the term used to describe a structure that forms when magma re-enters a magma chamber, causing the floor of the caldera or crater to lift. This uplift creates a dome-shaped structure within the caldera.

What is the magma type for a lava dome?
The magma type for a lava dome is typically viscous and silica-rich. This type of magma often leads to slower, more explosive eruptions that result in the gradual buildup of a dome-shaped feature composed of solidified lava.

Compare and contrast lava plateaus and dome mountains?
Both landforms develop as a result of the upward movement of molten material. Lava plateaus are high, level areas that form when thin, runny lava repeatedly erupts on the surface. In contrast, dome mountains are high, dome-shaped areas that form when hardened magma is uplifted and bends the layers of rock above it into a dome.
Is a volcanic dome non explosive?
Sometimes they are and sometimes they are not. The processes that form volcanic domes are non-explosive, but they can produce explosive eruptions. There are two different types of volcanic dome. The first is a lava dome. These form when very viscous lava is extruded onto the surface. Normally, highly viscous magma is gas-rich, and it is this gas that drives an explosive eruption. The formation of a lava dome can potentially mean two different things. In some cases a lava dome is a sign that a volcano is running out of gas and no longer has the potential to explode in the near future. In other cases a dome may just be the tip of a larger body of magma. The gas in this tip has escaped, allowing it to flow out and form a plug to the gas-rich magma beneath it. Pressure can built beneath this plug until the remained of the magma erupts explosively. The second type is a cryptodome. A cryptodome forms forms when viscous magma collects at a shallow depth beneath the surface and essentially inflates the ground above it. This in and of itself is not an explosive process, but can readily lead to an explosive eruption.
What is magma in a sill which pushes up to form a rock dome called?
The magma in a sill that pushes up to form a dome-shaped rock structure is called laccolith. Laccoliths form when magma intrudes between layers of sedimentary rock and causes the overlying rocks to arch upwards, resulting in a dome-like structure.
