How many active and non active volcanoes are there in Hawaii?

Three volcanoes are considered as active: Kilauea, Mauna Loa, Hualalai (without submarine volcanoes). Mauna Kea is a dormant volcano and many are now extinct. Because the complete list is long see the link below.

How are craters made?

Craters were probably caused by meteors that hit the moon. Craters can also be made by non-active volcanoes


What are non dormant?

What makes volcanoes non-explosive?

Non-explosive volcanoes will have low concentrations of gas in the magma.


What is the difference from a non volcano and active volcano?

Effusive eruptions occur when hot, (1200oC) runny basalt magmas reach the surface. Dissolved gases escape easily as the magma erupts, forming lava that flows downhill quite easily. Effusive eruptions build up gently-sloping Shield Volcanoes like Hawaii. Explosive eruptions occur where cooler, more viscous magmas (such as andesite) reach the surface. Dissolved gases cannot escape as easily, so pressure may build up until gas explosions blast rock and lava fragments into the air! Lava flows are much more thick and sticky so do not flow downhill as easily. These eruptions build up more steeply-sloping Composite volcanoes like this one in Chile.


Why does the moon have little water?

Because there is no active volcanic activity on the moon. For a planet or moon to develop water, it needs to have active volcanic activity. The steam from erupting volcanoes creates an atmosphere and condensation which, over millions of years, creates oceans. We know the moon had active volcanic activity millions of years ago, because there are pockets of ice on the moon. However, volcanic activity on the moon is now non-existent, therefore, no more water can be produced from volcanic steam.

Are volcanoes non living or living?

A volcano is nonliving. Although they do grow, they do not develop, or breathe, or reproduce, or eat.


How many non active volcanoes are there in new zealand?

All the South Island ones - many dozens. Essentially all the North Island ones as well apart from the central volcanic group, and Mayor and White islands. Quite a few of the N I ones may only be dormant - conspicuously Taupo.
