The mountain built up by a volcano is essentially a pile of material that has erupted from it such as lava, ash, and welded tuff.
No. it is a caldera and s supervolcano. A shield volcano is characterized by basaltic lava and effusive eruptions with little to no explosive character. Yellowstone produces rhyolytic lava and extremely explosive eruptions.
The Big Ben volcano on Heard Island was formed by repeated eruptions and the resulting lava flows. Over time the lava built up until it resulted in this huge volcanic mountain located in the Indian Ocean.
The Hawaiian Islands formed over a hotspot in the Pacific Ocean, where magma formed a column and rose through the Earth's crust, causing volcanic activity. The hotspot stays fixed as the Earth's plates move over it, which is why, currently, no island but the Big Island experiences volcanic eruptions.

No. Iceland is built up from numerous volcanic mountains.
Vocanoes can be helpful because the earth's first oceans and atmosphere were formed from the gases given off by volcanoes. Volcanoes have also shaped the earth's landscape, many of our mountains, islands, and plains have been built by volcanic eruptions.

Mount Fuji is a mountain that was built up over thousands and thousands of years from volcanic eruptions. it is that amazing symmetrical cone shape due to erosion.
The Hawaiian Islands were formed by volcanic activity millions of years ago. The islands formed as a result of magma rising up from the Earth's mantle through a hotspot beneath the Pacific tectonic plate. Over time, repeated volcanic eruptions built up the islands we see today.
A shield volcano.
Through geologic time, volcanic eruptions have shaped Earth's environment in many ways. The eruption of volcanoes built the continents on which we live. We owe much of the composition of our atmosphere to volcanic eruptions on the early Earth. Our oceans formed from water expelled during these same eruptions. Some of the world's richest farmland draws its fertility from minerals provided by nearby volcanoes. Volcanoes, particularly collapsed calderas, can develop geothermal systems when groundwater or rainwater seep into the volcano. Geothermally powered electric generating stations provide electricity in Iceland, Italy, and New Zealand. Volcanic processes are also responsible for precious and non-precious mineral deposits, which are formed when minerals precipitate from geothermal waters circulating in the rocks beneath and around volcanoes.Read more: What_benefits_do_volcanic_eruptions_bring

It was never built, it is a natural volcanic structure, so it is millions of years old.
