If volcanoes were the only things controlling our atmosphere, the air would be a toxic mix of methane, sulfur dioxide, and carbon dioxide. That's the way it for the first 3 and 1/2 billion years of earth history. However, during the last billion years, organisms in the oceans, soil, and land evolved to use more of these the volcanic gases in their life cycles, and they release oxygen and nitrogen as byproducts. As a result, nitrogen and oxygen came to dominate the air. There are just enough of the "greenhouse" gases left in the air to moderate our global temperature, so it is not too cold (freezing the oceans) nor too warm. That moderation is no accident, but rather it is the result of the very long period of evolution to produce a delicate balance between the actions of the inorganic Earth (especially volcanism) and the reactions of the organic life forms. See the interesting Gaia Theory.

∙ 14y agoVolcano's changed the landscape of the world by exploding because LAVA can change a life, yet landscape to. You could try this at home if your careful. Make a Volcano with baking soda and Vinegar (or if you know how) make sure ifs safe and make a landscape that doesn't mix so well with those ingredients then make it run over the edge and that way you can experience it (Ages 12 and under should be supervised by 18 and up responsible adult!) Hope this can help!

How does volcanoes change the Earth's atmosphere?
it change the earth atmosphere when magma flashes out then the earth surface will be dusty
How do volcanoes change how the earth looks?
They make landforms
Explain how volcanoes change the earth's surface?
by the moment of the tectonic plates
How do Volcanoes effect the atmosphere and climate?
Volcanoes erupt gases that change Earth's atmosphere. The volcanic ash and clouds can affect the air and atmosphere
What are six types of volcanoes?
1. Composite Volcanoes 2. Shield Volcanoes 3. Cinder Cones 4. Spatter Cones 5. Complex Volcanoes

What are the natural events that change the earth?
Wind, rivers (water), glaciers, volcanoes, and earthquakes. They change by taking Earth bits away.
What are two ways that volcanoes change Earth's surface?
I know the answers dumdies
How are earthquakes volcanoes and asteroid strikes different from weathering and erosion?
Weathering and erosion change the surface of the earth very slowly. Earthquakes, volcanoes and asteroids change the surface immediately.
How do Volcanoes effect the atmosphere and climate?
Volcanoes erupt gases that change Earth's atmosphere. The volcanic ash and clouds can affect the air and atmosphere

1. Composite Volcanoes 2. Shield Volcanoes 3. Cinder Cones 4. Spatter Cones 5. Complex Volcanoes
How many volcanoes are there are earth?
there are approx. 1500 active volcanoes on earth
When geographers look at how volcanoes and glaciers have shaped the face of the earth which of the 6 essential elements of geography are they studying?
environment and society
Why do volcanoes cause the most change in landforms?
Because volcanoes are formed under the crusts of the earth and the pressure formed by the massive heat emmitted from the volcanoe causes the crust to weaken to an extent at which it becomes vulnerable to change. This change becomes significant due to the fact that the crusts within the Earth are so large that one small change can alter how it sustains the upper layers of the Earth and, therefore, cause a change in landforms.
What are some of the powerful sources that change the earth's surface?
Earthquakes, volcanoes, floods. lots of natural disasters
