What are the main features of wildfires?
Wildfires may be started by lightning or by careless humans. They can become disasters when they rapidly move into developed areas, and firestorms can spread embers for several miles, overcoming firefighting efforts.
Wildfires naturally consume grass and brush, but can also involve trees, which may affect the wildlife within the area for several years. Some conifer seeds only sprout after a severe wildfire has melted their seed coats, increasing the chance that the seedlings will receive sunlight.
What is the definition of deforestration?
Deforestation is the process of clearing or destroying forests for agriculture, logging, or urban development, resulting in the reduction of forest area and loss of biodiversity. It is a significant environmental issue with consequences for climate change, ecosystems, and wildlife habitats.

It is caused by:
What are the effects of wildfires?
The effects of wildfires are: People lose there homes, animals are killed and also lose there vegetation, affects the air quality, the wind and heat. The good that wildfires do is they burn old dead trees, leaves, grass, anything that mother nature has not yet destroyed herself. Most fires leave a lot of animals homeless to say, which causes them to come into the city's nearest the fire and create a lot of havoc in the city around people.
Wildfires can occur anywhere where there is adequate heat, oxygen, and fuel. Anywhere it's dry hot and windy.
Wildfires can occur anywhere where there are miles of trees and the weather conditions are dry.
Does wildfires have any economic impact on the society?
Yes, wildfires can have significant economic impacts on society. They can result in destruction of homes, infrastructure, and natural resources, leading to financial losses for individuals, businesses, and governments. Additionally, firefighting efforts, recovery and rebuilding costs, and loss of tourism revenue can further strain economies.
What happens if you throw handful of cartridges in a fire?
The bullet cases soon explode like a pack of fire crackers. The lead shot may be shot out in all directions. The heat from the fire makes the gunpowder explode and the cartridge and the lead shot, will fire out in opposite directions with the ability to injure or even kill.
State one prudential reason and one moral reason for power sharing from the Indian Context?
Prudential reason: Power sharing in India promotes stability and mitigates the risks associated with deep-seated diversity by ensuring that multiple groups have a stake in the decision-making process, thus reducing the likelihood of conflicts and promoting overall peace and social cohesion.
Moral reason: Power sharing in India aligns with the principles of fairness, equality, and justice by giving voice and representation to all segments of society, particularly marginalized groups such as minorities or historically disadvantaged communities. This fosters a more inclusive and participatory democracy that upholds the dignity and rights of all citizens.
What kind of winds drive wildfires in California?
Santa Ana winds are the most common type of wind that drives wildfires in California. These dry, warm winds blow from the inland deserts toward the coast, causing low humidity levels and drying out vegetation, making it more susceptible to ignition and rapid spread of wildfires.
Fire is not a living thing because it does not have all of the seven characteristics. Nothing (so far) has proven that fire is made up of cells making it not living. Hope i helped and that you believe me :)
What is the red fire retardant that is used to put out wildfires made of?
Main ingredients: 85% water, 10% fertilizer (ammonia phosphate and sulfate ions), and 5% minor ingredients (iron oxide for color, clay or bentonite).
How it works: Works by coating fuels with moisture
How it is applied: Aerial application, dropped by aircraft.
Good News: It is non-toxic to humans.
Bad News: It may stain so should be washed off structures to prevent darkening of color. May be harmful to pets if swallowed (fertilizer poisoning).
Why is it red? Visibility! Easy to see from the air and ground
What are airplanes dumping on forest fires to try to extinguish them?
Airplanes drop fire retardants onto forest fires to help slow the spread of the flames by creating a barrier that prevents the fire from advancing. These retardants are typically a mixture of water, fertilizer, and chemicals that help to make the fire less intense and give firefighters a better chance of gaining control over the blaze.
How many people have been killed in a wildfire?
The number of people killed in a wildfire can vary significantly depending on the size and intensity of the fire. In recent years, wildfires have resulted in varying numbers of fatalities, with some fires causing no deaths while others have claimed multiple lives. Tracking the exact number of fatalities can be challenging, especially in larger wildfires with rapidly changing conditions.
What impact on humans do wildfires have on human population?
Wildfires can have several impacts on human populations. They can cause direct injuries and fatalities, destroy homes and infrastructure, displace communities, and result in the loss of livelihoods. Additionally, wildfires can have long-term health effects due to the release of harmful air pollutants. The social and psychological impacts, such as stress, trauma, and grief, are also significant for affected populations.
Are Policies that suppressed fires in the past causing fires to be worse today?
Yes, policies that suppressed fires in the past have contributed to the intensity and severity of fires today. By suppressing natural fires, fuels have accumulated over time, creating denser vegetation that is more prone to wildfires. Additionally, fire suppression policies have disrupted natural fire regimes and led to the loss of fire-adapted ecosystems, making landscapes more vulnerable to large-scale fires.
How do some plants trees and animals depend on wildfires?
Some plants, such as certain pine species, have adaptations that allow their cones to only open and release seeds when exposed to the intense heat of a wildfire. This helps these plants maintain their populations and regenerate after a fire. Additionally, wildfires can create open spaces and nutrient-rich ash, promoting new growth for various vegetation and providing habitat for certain animals that thrive in post-fire environments.
What is the cause of the Santa Ana winds?
The air is then forced down the mountain slopes out towards the Pacific coast; the air mass is further heated by compression as it drops in altitude before reaching the Los Angeles Basin western San Diego County and Tijuana (Baja California) at typical speeds of 35 knots. The southern California coastal region gets some of its hottest weather of the year during autumn while Santa Ana winds are blowing. During Santa Ana conditions it is typically hotter along the coast than in the deserts and the humidity plummets to less than 15%.
"Only YOU can prevent forest fires."
Previously, until 2001, it was "Remember - only YOU can prevent forest fires."
Originally, in 1944, it was "Smokey says -- Care will prevent 9 out of 10 forest fires," but this was changed to the above in 1947.

I hope so because I really like the show and I watched it everytime it did come on I didnt miss nothing because I was into it so much just wishing it will come back soon please
What what scale to measure the strength of a wildfire?
Bushfires are actually measured by the number and cost of insurance claims, and the death toll. They are not measured like earthquakes, on the Richter or Modified Mercalli scale, or like cyclones are measured as Category 1-5.
How many acres have been burned in the US from fires this year?
As of 7:00 AM June 30, 2008, there are nearly 1400 fires in CA, which account to nearly 411,520 acres lost so far. Considering that most of these fires are less then 50% contained (most are less then 10%) you can expect this number to climb.
How are fires naturally put out?
Firefighters use a variety of tools to extinguish wildfires, including planes and helicopters that drop a mixture of chemicals and water on the fire. They also use a Pulaski to dig a fireline, smoke jumpers, and hotshots.
What does a wildfire smell like?
Wildfires can produce a strong, smoky smell that is often described as acrid, bitter, or resembling burned wood. The smell can be quite overpowering, even from a distance, due to the various chemicals and particles released during the burning process.
