After a volcano erupts:
*ash settles on lava rocks
*lava cools
*wind carries spores to lava rocks
*pioneer species break down rocks
*soil forms
*large plants grow
*animal arrives
Incorporated in the mass of gases expelled from a volcano exist tiny rock particles called tephra. Tephra particles can adhere to gas particles and be carried for great distances according to the U.S. Geological Survey. The immediate effect of high concentrations of gas in the air result in closure of the airspace above and around the volcano to air traffic. Over time, upper level winds can carry volcanic gases around the world.
Ash particles impede air traffic as well as create immense breathing difficulties for people living near an erupting volcano. After a volcano, these 2-mm or smaller ash particles fly through the air, coating everything near the volcano. Ash particles can form a layer just like snow but it's much harder to remove. Combined with water, the ash becomes a mud-like mass.
The Federal Aviation Administration monitors volcano eruptions to prevent planes from traveling in areas with possible ash particles in the air due to the dangers of loss of visibility and possible engine failure. Ash particle clouds also rise into the atmosphere for transportation with the prevailing winds, making their existence dangerous to any aircraft flying in the vicinity.
Changes to the WaterAs the flow progresses, everything in the lava's path is consumed. Plants, animals, buildings, roads, and trees are burned completely. Lava flows cool over time and form new rock. Wind, rain, and water after lava flows with weathering to break down lava and turn it into soil.
When a volcano expels high volumes of ash, this coats the surface of the land around a volcano. This creates a dangerous condition of unstable earth with a thick layer of ash coating the sides of mountains and hillsides. Lahars are violent mudslides that result of waterlogged ash rushing down the sides of a mountain. These dangerous mudslides carry ash, rock, and debris, obliterating everything in its path.
Effects on Plants and AnimalsFish are extremely susceptible to a change in water quality. Volcanic eruptions often result in complete kills in streams and rivers near volcanoes. Ash contaminates the water, and burned or dead trees don't provide enough shade along these rivers to keep water temperatures down. High sediment content in the water prevents proper feeding, movement and reproduction. Birds naturally have difficulty flying in areas with ash clouds. Hot gases are deadly to birds as well.
Plants and trees suffer from the effects of heat generated by the eruption and deposition of ash and sediments. However, unburned trees recover and usually continue growing after ash is washed off the tree itself. According to the U.S. Geological Survey, the increased amount of erosion possible with ash and tephra depositions creates slower re-vegetation of any damaged areas. Tephra contains potassium and phosphorus that are valuable nutrients for rich, fertile soil. Weathering helps release these nutrients into the soil, creating the prime environment for renewed growth of native plants and trees.
After a Volcano erupts the lava that comes out dries out and can make a new layer of a volcano.
the magma dry's and then after its dry the magma is a new layer of rock
it creates more land and does terrible damage to the place it erupted
Alot of People die
It dries up
Volcanoes can erupt in any climate. Climate does not affect a volcano's ability to erupt.
The tectonic plates shifting is what causes an underwater volcano to erupt. Plate shifting is also the cause of tsunamis and earthquakes.
there lots of diffrent ways slow steady fast .
they mostly erupt in Hawaii
Cinder cone volcanoes erupt explosively, but not as violently as composite volcanoes.
No. Volcanoes erupt.
About 60 volcanoes erupt each year.
An unlimited amount of volcanoes can erupt at once
Volcanoes can erupt at any time of year.
Volcanoes can erupt in any climate. Climate does not affect a volcano's ability to erupt.

Active volcanoes erupt. Dormant volcanoes are quiet - but may erupt again some day. Extinct volcanoes have "closed up shop" for good, and will never erupt again.
Yes, they are.
there lots of diffrent ways slow steady fast .
Ash and Gas make composite volcanoes erupt i believe
they mostly erupt in Hawaii
Shield volcanoes erupt least violently cinder cone most violently and compost can erupt either way.
