They tell us that we need to be carefull, when there is a warning about a eruption. It also tellls us about the earth in many ways, such as: There is lava under the the land layer, there are many tectonic plates, and so on.
Volcanoes tell us a lot about the chemical composition of rock. They tell us what incredible force there is under the earth's crust.
They can be used to indicate were the earth has been hit by large astroids in the past.
The shockwave from an astroide can go through the "core" to the opposite side of the earth and there cause an eruption.
Volcanoes tell us more about the past than our future.

Although volcanoes also create new landforms such as geysers and hot springs which are rarely dangerous. When a volcano explodes, it gives off volcanic ash which has lots of nutrients to grow plants as well.

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
Do volcanoes only erupt on earth?
No, Astronomers have discovered erupting volcanoes on Venus as well as Earth

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
How many volcanoes are there are earth?
there are approx. 1500 active volcanoes on earth
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
What event always takes millions of years to change the surface of the earth?
volcanoes take millions of years to occur. it changes earth's surface.
What events always take millions of years to change the surface of the earth?
