Volcanoes affect the earth in many ways. The first being that they destroy much of the area surrounding them and in some cases lower the earth's temperature by many degrees. Earthquakes are a side effect of volcanoes.
When a volcano explodes it covers the ground (most likely) with ash and or lava which over time turn into rock forming new land and rocks. It also can destroy cultures and preserve them like in Pompeii. It also had a chance to make animals and human lose their. Volcanoes eruptions affect the earths system by pouring tons of carbon dioxide into the environment, heating up the earth. It kills trees and basically everything else in its immediate area, but it also deposits nutrient rich sediments into the environment which means it has beneficial and negative effects.
All Volcanoes are located where oceanic &continental plates meet. As these plates float on the molten rock of the earth's interior, they collide with one another, releasing huge amount of energy. The rocks of the lower plate melt in the Earth's hot interior, creating even more magma. This magma, which is thoroughly mixed with gases, accumulates until the pressure becomes so great that it erupts in the form of a volcano through fissures in the earth's surface.
Volcanoes are believed to have been around since earth was created which would be approximately 4.6billion years. There isn't a certain amount that volcanoes can erupt for average volcanoes could go on for days but it depends on the volcanoes, some are so explosive that it is over in a matter of seconds/minutes but causes great damage to the surrounding area some can last a few hours, some can last a few days, but some volcanos never stop erupting, they are always active.
What else can I help you with?
When was kilauea formed?
It was formed in 1759
When were volcanoes invented?
The first volcanic eruption happened before the first human existed. The earth has had erupting volcanoes since just about the first years that it existed - about four and a half billion years ago. In fact, some of the best places for finding the fossils of ancient humans are in east Africa because they are buried in ashes of ancient volcanoes that erupted around them. The planets Mars, Venus and Jupiter's moon Io also have volcanoes on them.
The hawaiian islands are a chain of volcanoes how are volcanoes like these formed?
The Hawaiian Islands were formed by a hotspot underneath the Earth's crust, where magma rises to the surface and creates volcanoes. As tectonic plates move over the hotspot, new volcanoes form, creating a chain of islands. Over time, the older volcanoes erode and subside, while new ones continue to grow, extending the chain.
How were Mars' volcanoes formed?
Since Mars lacks plate tectonics, the volcanoes were probaly formed by hot spots. These are areas where extra hot mantle material wells up and collects beneath the crust where some of it melts and rises through the crust to form volcanoes.
How many years have been volcanoes been around?
Volcanoes have been active on Earth for millions of years, with some estimates suggesting they have existed for over 4 billion years. The Earth's geology is constantly changing, leading to the formation and eruption of volcanoes over the planet's extensive history.
Why do you have volcanoes?
Well, if volcanoes didn't exist, neither would the earth. Since volcanoes helped build the earth.
When was kilauea formed?
It was formed in 1759
Explain how erupting volcanoes contributed to the formation of oceans?
Some theories regarding the origin of Earth's water say that it was "in" the Earth since it formed and that Volcanoes have brought it to the surface over geologic time. However, recent scientific work using the isotopic composition of Earth's water point to it having been delivered to Earth by meteorites and comets after the Earth was formed. This said, volcanoes are certainly part of Earth's current water cycle as areas of hot springs and mid oceanic, black smokers prove.
Why does the earth now have natural disasters such as earthquakes volcanoes and tidal waves?
The Earth has always had natural disasters - ever since it formed ! It's simply because the Earth's crust is unstable - and weather patterns are not totally predictable !
How many years have volcanoes been around for?
They have been on Earth since Earth has existed.

How many snowflakes have landed on Earth since it was formed?
several.
Do volcanoes have oxygen?
No. A volcano erupts molten material from inside the earth. Actual fire is not involved:the material is hot to begin with and has been since the formation of the earth.
Which volcano was the first volcano to erupt?
Nobody knows or will ever know. Earth has had volcanoes since the crust first formed, and all rocks from the early crust apart from some small zircon crystals have been destroyed be geologic processes.
