Volcanoes usually formed as a result of?

Answer 1

Volcanoes do not form in just any place. There are certain places on earth where they form.

Most volcanoes form at convergent boundaries. These boundaries are between two plates that move toward each other.

These boundaries are in form of trenches, ocean ridges and transform faults.

The area where many volcanoes have form is around the pacific plate. This area is called the Pacific Ring of Fire.

A volcano may also form at a divergent boundarywhere two plates move away from each other. When two plates pull apart, a long, deep crack called a rift is formed. Magma flows through the rift and builds up, resulting in the formation of volcanic islands.

Some volcanoes form far from the edges of a plate. The Hawaiian Islands which are volcanic islands are located in the middle of the pacific plate. Scientists believe that the islands sit on top of a hot spot under the Pacific Plate. A hot spot can melt rocks. Magma deep inside the earth flowed to the crust to form volcanoes. The volcanoes that rose above the ocean formed the Hawaiian Islands.

Answer 2

When the lava reaches the earth's surface it starts to cool and harden into rock. This happens every time the volcano erupts. Eventually the cooled down layers build up thus adding to the size of the volcano. To make it easier to understand, imagine grabbing a handful of sand and pouring it back onto the ground, grab another handful and pour it onto the existing mound, repeat this and then notice how it grows, this is the same principal as the volcano.

Answer 3

Volcanic mountains are formed by ___.

Lava

Gravity

Folding

Sliding

The awnser is Lava

You might want to double check it to see if it is correct if its not the right Qwestion or Awnser.

Answer 4

Volcanoes are usually formed as a result of a convergent boundary, where both plates are continental a divergent boundary, where at least one of the plates is oceanic a transform fault boundary, where both plates are oceanic a convergent boundary, where at least one of the plates is oceanic

Answer 5

Volcanoes are usually formed as a result of tectonic plate movements causing magma to rise to the surface through weak points in the Earth's crust. This magma can then erupt, creating volcanic activity. Volcanoes can also form at hotspots or subduction zones where the Earth's crust is under pressure.

Answer 6

Mountains are formed by plate tectonics colliding
