Answer: For every 10˚ slope, the fire will double its speed. For example, if a fire is travelling at 5 km per hour along flat ground and it hits a 10˚ slope it will double in speed to 10 km per hour up the hill.

By increasing in speed the fire also increases in intensity, becoming even hotter.

The opposite applies to a fire travelling downhill. The flames reach less fuel, and less radiant heat pre-heats the fuel in front of the fire. For every 10˚ of downhill slope, the fire will halve its speed.

Fires tend to move more slowly as the slope decreases.

Vegetation (fuel)

Grass can burn early and quickly on hot, dry, windy days.  

Branches, twigs and leaves dropped from shrubs and trees become fine fuels, which burn easily. These can give off far more heat when they burn

Fibrous and dry tree bark can carry fire to treetops. The fire can then break away and spread further

Dry branches, twigs and leaves and other fine fuels found on the ground can also burn easily.

Weather conditions

Bushfires are unpredictable and vary greatly according to weather conditions. They often start on hot, dry, windy days.

Temperature

A string of hot days dries out vegetation, making it easier to burn. This can be made even worse by underlying dry conditions caused by lack of rain.  

The drier the vegetation the easier it will burn.

A fire spreads as a result of burning embers, radiant heat and direct flame contact.

Wind

Wind influences the:

speed at which a fire spreads

direction in which a fire travels and the size of the fire front

intensity of a fire – wind provides more oxygen

likelihood of spotting – burning pieces of leaves, twigs and bark (embers) that the wind carries ahead of the fire. These cause new 'spot fires' to ignite.

Wind change

A change in wind direction is one of the most dangerous influences on fire behavior. Many people who die in bushfires get caught during or after a wind change.

In Victoria, hot, dry winds typically come from the north and northwest and are often followed by a southwest wind change. In this situation the side of the fire can quickly become a much larger fire front.

Answer:

Mobile phones have become a staple of our society, with everyone from elementary school kids to senior citizens owning at least one. Although mobile apps and texting have made our lives easier, some question the impact they’ve had on the relationships we have with one another.

After losing part of her vision three years ago, Dr. Lisabeth Saunders Medlock, PhD, CLC, owner of Life by Design Coaching, can no longer see her cell phone. She replaced her Blackberry with a flip phone that reads out loud to her.

“I have a mobile phone that is a basic flip phone where it talks aloud to tell me who is calling and reads all the screens and text aloud,” she says. “I really love the fact I am not always looking at a phone. I can interact and socialize and truly have to be in each moment because I cannot distract or amuse myself with my phone.

“It is also freeing to not really have to respond to emails or even text messages when I choose to not be available. What it forces me and others to do is pick up the phone and talk. Having those dialogues has deepened friendships and allowed me to get to know people better.”

“And if I really needed to use GPS or look up a number, I am usually with a person who can do that for me,” she continues. “I am glad I cannot use a smartphone because it would waste time and energy and probably make me less smart.”

Addicted to Mobile Phones

Todd Starkweather, General Studies program director at South University, Richmond believes a lot of people are at least somewhat addicted to their cell phone.

“I see it frequently in my classes,” he says. “I make certain that students using their phones don’t disturb the learning of others, but do not make an active effort to police an individual who may not be paying attention.”

Starkweather says it’s up to the student whether or not they choose to spend class time listening and learning, or wasting their time on the phone.

As for the impact mobile phones have made on his own personal life, Starkweather says it’s helped him to stay more connected to family and friends than he was in the past.

I never take my phone into my classroom when I teach. Somehow I’m able to get through that hour and 40 minutes without my phone.

“I suppose I’m in much more constant contact with individuals, getting frequent updates,” he says.

He remembers the days before mobile phones when it wouldn’t seem like a long time to go eight hours not hearing from close friends or family members.

For example, before everyone had mobile phones, he says if a friend went on vacation you probably wouldn’t hear from them while they’re away, but now you often receive frequent updates of their journey from the road.

Although having the ability to connect with anyone, at almost anytime, is convenient, Starkweather doesn’t feel it’s necessary to have the device glued to his side at all times.

“There are times when I simply put the phone away, times I don’t need it,” Starkweather says.

“I never take my phone into my classroom when I teach,” Starkweather adds. “Somehow I’m able to get through that hour and 40 minutes without my phone.”

Mobile Phones Changing Interpersonal Communication

Saunders Medlock advises mobile phone users to set rules and practice good phone etiquette.

“Some of these are no phones at a meal, whether it be at home or eating out; no checking the phone on a date or when you are out with friends; phone is off at critical meetings and set to vibrate at others,” she says. “And it goes without saying you should not be on or using your phone while driving.”

She says people are in the habit of checking their cell phone in short intervals of time, like every five minutes.

“I have heard people say that they are afraid they will miss something if they do not do the checking,” she says. “And when people are not doing anything else they tend to interact with their phones to distract or entertain themselves. I have seen people in the line for the bathroom playing with their phones.”

She believes this constant reliance on mobile phones is having a negative impact on people’s interpersonal skills.

To understand the effect of Smartphones and social media on interpersonal communication, she recommends reading the book, Alone Together: Why We Expect More from Technology and Less from Each Other, by Sherry Turkle.
