When magma has solidified in a volcanoes vent it is known as a volcanic plug. In some cases when there is a plug present in a stratovolcano, it can lead to very large explosive eruptions as pressure builds within the volcano.

Actually, the hardened magma left in a volcano's pipe after the surrounding softer rock has eroded away is known as a volcanic neck or plug, not a batholith. A batholith is a large mass of igneous rock that has crystallized from magma deep within the Earth's crust, typically covering an area of more than 100 square kilometers. In contrast, a volcanic neck represents the solidified remains of a volcano's conduit.
There are currently no active volcanoes in New England. The region's geologic activity is largely characterized by old, extinct volcanoes and much of the volcanic activity that shaped the area occurred hundreds of millions of years ago.
Yes, Bear Butte is actually a laccolith, an intrusive body of igneous rock, but any magma or volcanic material has long since eroded away.
New England primarily features ancient volcanic rock formations, as most of the region's volcanoes are extinct and not currently active. The most notable types are shield volcanoes and stratovolcanoes, with remnants found in areas like the White Mountains of New Hampshire and the Green Mountains of Vermont. These volcanoes formed during various geological periods, but significant volcanic activity ceased millions of years ago, leading to the eroded landscapes seen today.

they can be eroded by wind and rain and hardened by heat.
Such formations are called seamounts.
Volvanoes do not have baby volcanoes. They simply leave behind the neck of the volcano when it gets weathered or eroded. That's just a not smart question. Sheesh, listen in science class!
Yes. The Devils Tower is the core of a volcano that has become dormant, And the land around the core eroded away with time. And then there's the Super Volcano under Yellowstone National Park.
The rocks are formed due to the erosional activity of air. The hard part remaining are the balancing rocks and the soft sediments around the rocks got eroded by the wind.
Well, earthquakes can cause erosion of rocks, such as maybe large chunks of a mountain being eroded away after an earthquake. And volcanoes can form new land masses, such as islands. Hope this helps!
Near active or extinct volcanoes, eroded mountains, or rift zones. Can also have been transported to other areas by ice or water.

The eroded particles may be carried by water, wind or ice to other locations like the lowland regions or into the ocean and lakes.The eroded materials build up and under their own pressure gradually become hardened into sedimentary rock.
