Explosions made waves in space which led to the creation of a solar nebula, which is a flattened cloud of gas and dust.
What is The Nebular Hypothesis
100
An extra terrestrial body that travels rapidly through space.
What is a Bolide
100
Name 3 types of fuel.
What can be woody debris, fallen trees, grasses, shrubs, decaying organic matter, small children.
100
Because these evolved, wildfires became a thing.
What are Trees
100
When a fire leaps from the ground into the trees.
What is a Blow Up
200
A layer of debris/an ejecta blanket (rock fragments blown out from the crater) that provide evidence for past meteor impacts.
What is Breccia
200
Rocky, metallic material, 10m-100km in diameter from the -------- belt.
What is an Asteroid
200
Which 2 of the 3 elements of a wildfire can be exhausted for the fire to go out?
What are Fuel and Heat
200
Has destroyed forests throughout western Canada, 80% of trees are impacted; wildfires actually control this critter.
What is the Mountain Pine Beetle
200
Burning off fuel in front of the main fire to create a block.
What is an Escape Fire.
300
Composed of rock, gas, and ice, it creates light as gas from solar radiation heats it up. It passes close to Earth's surface every 75 years.
What is Halley's Comet
300
Small particles, ranging from dust to a few metre across.
What is a Meteoroid.
300
The 3rd phase of a forest fire in which combustion ceases.
What is the Extinction Phase.
300
The chemical degradation of large hydrocarbon molecules into smaller ones, occurs in the presence of heat.
What is Pyrolysis
300
Bumps and spots in meteors scoured away by air and heat.
What is a Depression
400
A bolide hurls towards Earth, but leaves no crater
What is an Airburst
400
A meteoroid that has entered Earth's atmosphere.
What is a Meteor
400
What are 3 ways heat can be transferred?
What are Conduction, Radiation, and Convection.
400
Potential for a wildfire in an area.
What is a Fire Regime.
400
Why wasn't the damage at Chelyabinsk worse?
The energy expelled was at a shallow angle, so energy exploded forwards and not down towards the ground.
500
Complex crater, 100km in diameter, one of 5 largest in the world, formed 214 million years ago. Faulting has caused rim to collapse into lakes.
What is the Manicouagan Crater
500
A meteor that has struck Earth
What is a Meteorite
500
1 of the 3 phases in which ignition will happen continuously.
What is the Combustion Phase.
500
Natural service functions of wildfires.
What are any of reducing competition for sunlight and resources, allowing certain species to flourish, trigger some seeds to grow and flowers to stimulate.
500
How come the meteor wasn't detected in advance?
Days before, it was close to the sun so no telescope could have detected it.
