It starts with seafloor spreading, then when the oceanic plates converge, or collide, the less dense plate with sink under the denser plate and will shove it into what is called a subduction zone. Then the rock will melt and erupt out of the peak that was formed by the two plates colliding. It will not erupt until it has enough force though.

∙ 11y agoWhen volcanoes erupt they eject ash and/or molten rock. This material builds up over time, often forming a mountain. If this process starts on the sea floor the mountain will build up, and become an island once it gets above sea level.

Where do chains of volcanoes in the oceans and lines of volcanoes on land is that they formed at?
they are fromed at hot spots
How do volcanoes affect Hawaii?
Hawai'i was formed from volcanoes. The shape of the islands (volcanic mountains) affects the weather. Volcanic activity causes eartquakes, eruptions on the Big Island cause it to continue to grow, cause fires, close roads. Gasses from the volcanoes can cause vog (volcanic smog) and volcanoes have produced fertile soil in Hawai'i.
Is there volcanoes in the Bahamas?
No, there are no volcanoes in the Bahamas.
Why are volcanoes usually near hills?
volcanoes are usually the mountains,the plate boundaries colliding depend on where the volcanoes are formed so they are not purposely always formed by mountains.
How earthquakes volcanoes and mountain's formation are related to plate tectonics?
Earthquakes, volcanoes and mountains are formed via plate tectonics. When the large continental plates collide, they either cause temporary earthquakes, or more permanent features such as volcanoes and mountains.
What oceans are the Hawaiian Islands formed by?
Volcanoes.
Where do chains of volcanoes in the oceans and lines of volcanoes on land is that they formed at?
they are fromed at hot spots
What did chemist learn about the mons surface by analyzing moon rocks?
The rocks were similar to rocks formed by volcanoes on Earth, suggesting that vast oceans of molten lava once covered the moon's surface.
What was earth covered with when it first formed?
liquid water in oceans with deep sea hydrothermal vents a+ erupting volcanoes and poisonous gases
How did salt get into the sea?
Salt is dissolved from the earth and transported in seas/oceans by rivers; some salt is formed by submarine volcanoes eruptions.
How does chloride enter the oceans?
Volcanoes
Where does the salts in the sea come from?
Salts are dissolved from the earth and transported in seas and oceans by rivers; a small part of salts is formed from submarine volcanoes eruptions.
Explain how earths first ocean's formed?
When the volcanoes erupted the gas from it made clouds and when it rained it started to for layers of water and that's how the first oceans formed......i think

Where are most of the earths volcanoes hidden?
The Oceans
How do volcanoes affect the compositions of the oceans?
they dont
How were oceans formed?
It was about 4 billion years ago, that the Earths oceans formed
