Seventy percent of all forest fires are started by lightning. Carelessness causes starts some of them, and occasionally arson (some of the most devastating fires in California the last few years have been determined to have been started by arson).

In Coal seams depp underground, these fires are started by lightning and can burn for many years, often fkaring up and causing forest fires

About 3000 brush fires per year are started by lightning strikes.

Obviously natural forest fires are caused by a natural force, such as lightning. Human made forest fires are caused by something man-made.

lightning pow :)

Some forest fires have been known to be caused by lightning.

About 3,000 fires a year are started by lightning strikes.

Forest fires can be caused by a lightning strike, by sunlight being magnified by a broken bottle, or deliberately by an arsonist (a person who criminally lights fires).

Thousands of fires are caused by lightning every day. Most of them burn themselves out naturally.

forest fires usually occur in the hottest season because of lightning sometimes occur and the sun's heat on the dried grass and leaves

Several probable ways are: forest fires can be started deliberately by arsonists, or by a lightning strike, or by sunlight shining through the thick bottom of a broken clear glass bottle, acting like a magnifying lens. It could also be started by sparks blown into the air from a nearby garden bonfire, or a controlled burn on farmland that gets out of hand.

lightning but you cant provent it it comes naturally brooke you cant controll lightning

Most commonly? In nature, that would have to be lightning. Smokey the Bear has been telling us for years about how sloppy campers can cause forest fires, and he's right, but 70% of forest fires are ignited by lightning.

yes it can cause fires because lighting finds the quickest route to the ground

Lightning strikes are the Number Two cause of forest fires. Human error is Number One. At one time, it was thought that forest fires are ONLY detrimental. That theory has evolved to reveal that forest fires clear out the underbrush & fertilize the forest floor so that the big trees like Redwoods, Bristlecone Pines, Junipers, Pinyons and other conifers may flourish.

About half...

William G. Morris has written: 'Lightning storms and fires on the national forests of Oregon and Washington' -- subject(s): Forest fires, Lightning

Most often they are started by lightning.

He doesn't. Smokey is concerned only with fires caused by human carelessness.

there are at least 400 fires started by careless smokers each year.

Cloud-to-ground lightning naturally starts hundreds of forest fires every day.

A muck fire burns under the ground and is stirred up by lightning. THey cannot be put out, you cant see them, and they are not destructive. Forest fires take place in forests, and they burn down trees.

More buildings would be destroyed by fires started by lightning

3000 bush fires are made by lightning per year

There are two main causes of forest fires. Firstly is human carelessness as people fail to extinguish camp fires properly or are careless with matches and cigarettes. The second cause is often due to lightning strikes in forested areas.

I heard that lightning is a common cause of forest fires.

Lightning is the major cause of forest fires. careless smoking, campfires that are not put out properly, left untended, or lit in droughts, deliberately lit fires used to prevent forest fires sometimes escape containment, and people (arsonists) also set fires on purpose. War andhuman error also cause forest fires. ----------------------- ***Not according to Smokey the Bear. See the related link below, read the discussion, get the facts.

Forest/brush fires.

We know that every year there are have so many forest fires, most of them are caused by lighting, Because we know there are so many trees in forest and also have so much bacillus and dry leaves, dry trees, The dry leaves and trees are easy blazing. when lightning, the lighting will make a huge heat power, when the heat touch the dry leaves and trees, the fire produced, so that's why lighting cause…

Lightning starts hundreds of fires every day, during fire season. Human carelessness accounts for a large number of fires in some areas that are accessible to humans.

Cigarettes have been the cause of thousands of house fires and forest fires over the many decades they have been used.

well given the fact that most forest fires start from lightning..... you tell me

More than 100 muck fires have occurred during this year muck fires are started by lightning that hit a dry area.

Humans have deliberatly caused forest fires, or they may have camped and forgot to put the fire out. but in coniferous forests it may be caused by lightning

Causes of Forest Fires. Wildfires can be ignited by a variety of occurrences. In addition to lightning, human-related activities start a large number of fires every year. Unattended or out-of-control camp fires, a discarded burning cigarette, arson, or even equipment use can set off a blaze.

Keep a sense of proportion and make your own decisions after doing a little of your own thinking; lightning has been causing uncontrolled forest and grassfires for over a billion years. In the 1920s, the USForest Service 'decided' forest fires were 'worth' fighting, and developed the 'Smoky the Bear' campaign for prompt reporting/fighting forest fires. In 1999, the USForest Service 'decided' forest health was best maintained by controlled burns and allowing lighning-strike fires to 'naturally'…

I would say yes. Many forest fires are started from lighting in my area.

Muck fires are underground fires under a layer of duff in marshy areas. Muck fires are started when lightning strikes the ground and starts to burn. THEY ARE MAINLY IN FLORIDA

lightning about 60% humans about 40% - 45% that caused lightning - 55% that caused people - 15% that caused companies and other industries

A forest fire will ALWAYS stop. Furthermore forest fires, usually caused by lightning, are a natural part of the wilderness. In fact several plant species benefit from fires as part of their life cycle. Nothing. Forest Fires are a natural occurence. The scary question is what will happen if hippies keep trying to prevent forest fires! Massive loss of life, massive loss of property, environmental damage, etc; have all happened, and will happen on a…

It usually starts by one lightning strike on a very dry tree to start the fire. since lightning is made up of electricity, it gets so hot that when it strikes a dry tree, it will catch on fire and that's all it takes to start a forest fire.

Catastrophic events such as, a tornado, hurricane, flood, drought, and some forest fires which are sparked by lightning.

The main reason for forest fires in hot summers is simply this: If the summer is excruciating hot and there is little to no rainfall, the trees, grasses, etc. will become dry. Dry leaves/trees, etc. + campfire, lightning, etc. = Forest fire.

Natural wildfires are often started by lightning, extreme heat, and volcanic eruptions. In damp conditions the fire would not spread far, however during dry periods the damage from the fire could be vast.

The main natural disasters that happen at the Deciduous Forest is fires and floods. Fires occur due to lightning and spread fairly quickly due to all the trees.

Many things, these include cigarettes, charcoal, matches, even a lightning strike. ----------------- I just checked with Smokey the Bear: While lightning strikes can cause forest fires, nine out ten are human caused. Sad, ain't it?

Trees can act similar to lightning rods. This is due to their extreme height. If lightning strikes a tree, heavy limbs could fall on people/animals and forest fires may occur.

Muck fires are fires that burn underground. They get started by lightning hitting a dry area. They are most common in Tampa Bay, a place in Florida. They can burn for sometimes years at a time. Most are impossible to get rid of. and admit smoke everywhere
