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 a volcanic dome?
I don't know about viscous, but a lava dome is a steep-sided dome of thick lava extruding from a volcanic vent.a viscous lava dome is when the lava from the volcano contains alot of silica. Viscous=sticky. So the lava cools quickly of the sides of the volcano. And often a viscous lava dome volcano is explosive.
What is formed when magma begins to form a dome shape which will push the rust outward in a hill formation?
When magma pushes upward in a dome shape, it creates a geological feature known as a volcanic dome or lava dome. This occurs when viscous lava accumulates at a vent, causing the surrounding rock to bulge outward. As the dome forms, it can lead to the uplift of the crust, resulting in a hill-like structure. Volcanic domes are often associated with explosive eruptions as the pressure builds within the magma chamber.
Does Mount Fuji have explosive or non explosive eruptions?
Mount Fuji typically has non-explosive eruptions, which are characterized by the slow release of lava and volcanic gases. However, there is also some evidence of explosive eruptions occurring in the past, which have produced ash clouds and pyroclastic flows.
Is a lava dome constructive or destructive?
A lava dome is considered a constructive volcanic feature. It forms when viscous lava erupts and piles up near the volcanic vent, creating a dome-shaped structure. While eruptions that form lava domes can be hazardous locally due to potential collapse or explosions, they generally do not produce widespread destruction like explosive eruptions.
What Is most of the sea floor covered with from non explosive volcanic eruptions?
Most of the sea floor is covered with basaltic rock from non-explosive volcanic eruptions. This type of rock is formed when magma cools quickly upon contact with seawater, creating the characteristic pillow-like formations commonly seen on the ocean floor.
What are the different types of volcanic eruptions?
Non-explosive and Explosive
What are the 2 types of volcanic erruptions?
explosive and non-explosive
What is a volcano explosive index?
Volcanic explosive index is a measure of how explosive a volcanic eruption is based largely on the amount of material released. It ranges from VEI-0 for non explosive eruptions to VEI-8 for massive super eruptions.
What type of plate boundary have abundant non explosive volcanic activity?
Divergent boundaries. :)

What are the three types of non-boundary mountains?
The three types of non-boundary mountains are volcanic mountains, dome mountains, and fault-block mountains. Volcanic mountains form from volcanic activity, dome mountains are created by the uplifting of large blocks of crust, and fault-block mountains are formed when large crustal blocks are uplifted along faults.
How are dome mountains different from volcanic mountains?
Dome mountains are formed by the uplift of rock layers in a broad region, creating a dome-shaped structure, while volcanic mountains are formed by the accumulation of lava and volcanic ash erupting from a volcano. Dome mountains do not have volcanic activity associated with them, whereas volcanic mountains are typically associated with magma and eruptions.
Does Mount Fuji have explosive or non explosive eruptions?

What are some hazards from both explosive and non-explosive eruptions?
Explosive eruptions can produce pyroclastic flows, ash plumes, and lahars, which are fast-moving mixtures of volcanic material that can be very dangerous and destructive. Non-explosive eruptions, such as effusive eruptions, can still pose hazards like lava flows, gas emissions, and volcanic gases, which can impact air quality and potentially cause health problems for people living near the volcano.
What about magma affects how explosive an eruption will be?
The composition of the magma affects how explosive a volcanic eruption will be.
