The cone volcanoes are created by the upwelling of liquid hot rock from the earth's interior. This is called Plutonic rock, along with Granites which however are cooled before they reach the surface. The hollow left at the top of a volcano is formed when the pool of magma withdraws and the volcano becomes quiet.
Some volcanoes do not form cones. Lake Taupo in New Zealand, and Yellowstone National Park in the US are notable examples, where there was a violent explosive eruption which however did not produce a local cone.
The volcanic eruption, whose caldera is now filled in by Lake Taupo occurred about 26000 years ago and ejected over 1 000 cubic kilometres of material! It has had 28 eruptions in the last 27 000 years, and in one it ejected about 30 cubic kilometres in a few minutes. The last eruption was about AD 186.
Naturally, once erupted, erosion takes its toll on the exposed and fairly unstable material.
There is a third type of volcanic material, the Flood Basalts, which are of continental scale! These ejections are of a very liquid material, covering giant areas, but without conspicuous surface relief.
Yes fiords are formed through wave erosion. A sea arch is also formed through wave erosion. Other things that can be formed through erosion are canyons, cliffs, and caves.
Some common surface features formed by water erosion include valleys, canyons, river channels, and waterfalls. Water erosion can also create features like meanders and deltas in river systems, as well as coastal cliffs and caves along the coastline.
No, mountains are not formed by erosion. Mountains are typically formed by tectonic forces such as plate movements, volcanic activity, or folding of the Earth's crust. Erosion can shape and alter the surface of a mountain over time, but it does not create the mountains themselves.
A cirque, also known as a Cwm or Corrie, is a feature of glacial erosion, formed in a mountainside.
A mountain is a sharpened peak formed by the glacial actions of three cirques on a mountaintop. Since we know that a cirque is a bowl-shaped basin formed by EROSION and a mountain horn is formed by three CIRQUES it becomes clear that mountain horns are formed by erosion.

volcanos
continents where formed by under water y=volcanos
it was formed be volcanos
Volcanos
Gulfs are formed by erosion. Gulfs are formed by erosion.
Mountains can be formed by erosion!
volcanos under water exploded and rocks formed it.
Creep is formed by erosion.
from the ashes and lava of volcanos.
Yes volcanos are formed on convergent and divergent plate boundries but NOT on transform boundries
Yosemite National Park and lakes were formed by erosion in California.
