Why aren't volcanoes constantly erupting?

Answer 1

Volcanoes take thousands of years to make by tectonic plates converging and diverging, the necessary pressure for some volcanoes to erupt takes hundreds to thousands of years to build up. Some volcanoes are constantly eruptive, these eruptions having little explosive properties, other volcanoes don't erupt for thousands of years.

Answer 2

Volcanoes are not constantly erupting because the magma beneath the Earth's surface needs time to accumulate and build up pressure before it can reach the surface. Additionally, the movement of tectonic plates controls the location and frequency of volcanic activity, leading to intermittent eruptions rather than constant ones.

Answer 3

Because the volcano has gone dormant. This means that there is no pressure on the magma beneath, thus no eruptions.

Answer 4

they do and some are not active any more so they don't erupt.

Answer 5

is it because there is no earthquakes that area
