How long does the natural disaster ushually last?
* floods * bushfires * volcanic eruptions
What are some long-term effects of volcanic eruptions?
Air pollution is a major effect of volcanic eruptions. Over the last few years Mount St. Helens has been the number one pollution source in the Northwest.
Do trees grow around volcanoes?
Yes. Many volcanoes have trees on them, especially those that go for long periods wthout erupting or with eruptions that do not have far-reaching effects.
What are the good effects of volcanic eruption?
Volcanic ashfalls can restore minerals to depleted soils. Volcanoes can vent geothermal steam that in some areas generates power (but actual eruptions can disturb the process). The main benefit to living things is the creation of new islands at sea, which generate new local biospheres.
How does volcanic ash help Java?
Volcanic ash can have a variety of effects. In some eruptions it can fall like snow, but with different effects. The silica in the ash can be toxic to plants and animals. The weight of the ash can bring down trees and collapse roofs. Large areas can be buried. Over the long term, however, volcanic ash, once weathered, makes very fertile soil. Volcanic ash is also harmful when inhaled and can damage the eyes and lungs. It can clog the engines of cars and aircraft, and can bring down planes in flight. In some eruptions, superheated clouds of ash and gas called pyroclastic flows race down the slopes of a volcano. Anything living caught in such a flow will burn to death. When ash mixes with rain or melted snow and ice it can form mudflows called lahars. These lahars behave like floods, but are denser and more destructive, burying the areas where they come to rest in hardened mud. Lahars can fill in stream beds as well, causing floods.
How often do volcanic eruptions last?
How long is a peice of string. They vary from seconds to decades.

Describe the most destructive or recent eruption and what effects it has had on the local landscape and climate?
The most destructive recent eruptions are caused by movements along faults. It can destroy the local landscape and cause long-lasting effects on plants and animals.
Do trees grow around volcanoes?
Yes. Many volcanoes have trees on them, especially those that go for long periods wthout erupting or with eruptions that do not have far-reaching effects.
What is the principal source of water in ocean?
outgassing- water/ dissolved gasses emitted through volcanic eruptions over long periods of geologic time
Why are the Hawaiian islands in a chain?
Due to volcanic eruptions forming islands along a weakness in a long line of the sea bed, the Hawaiian Island chains was formed.
What are long term effects of volcanoes on the planet?
Volcanoes can usually have super eruptions, which could have effects like species bottlenecks or even extintions. They can also change the geological aspect of earth in the long term.

What are the effect of volcanic eruption?
They bring about minerals, can form new land, and in the long term can fertilize soil.

How volcanic eruption cool the earth?
It's plain and simple. As the eruption comes to a beginning, the place where the eruption should occur gets highly elevated. If certain surface was a bit flat, it wouldn't be anymore. Also, the vegetation and pretty much everything gets destroyed, but they say the volcanic earth can be useful sometimes.
