What do you know about Wildfires…

A

Climatic(sun), sun/lightning sets vegetation on fire (which are effective fuels, so the fire spreads)

Q

What do you know about droughts?

A

Climatic(no rain), occurs when more water is used than is replenished, and can be fueled by changing wind patterns

Q

What do you know about floods…

A

Climatic, when there is more water when the can can absorb, happens often in flood plains, and so civilizations in flood plains are flooded more

Q

What is the difference between a hazard and a risk? (Good to know, but probably not tested on this)

A

A hazard is anything with the potential to do harm and a risk is the likelihood that a hazard will cause a specified harm to someone

Q

What are tropical storms?

A

Natural hazards where there is an area of low pressure with winds moving around the calm central eye of the storm. It has heavy winds and rainfall.

Q

Tropical storm- Step 1, 2, 3, 4, 5,

A

1.Air is heated above the surface of the warm tropical oceans, and the warm air rises rapidly under the low pressure conditions 2. As the air rises, it cools and condenses to form cumulonimbus clouds which generate torrential rainfall. The heat given off when the air cools powers the tropical storm (latent heat) 3. The rising air draws up more air and large volumes of moisture from the ocean, causing strong winds 4. The Coriolis effect causes the air to spin upwards the calm central eye of the storm. Cold air sinks in the eye, meaning that there is no cloud, so it is dryer and much calmer here 5. The tropical storm travels across the ocean in the prevailing wind. When the tropical storm meets land it loses its power as it loses a source of moisture and heat, so it weakens, and is further slowed down by friction upon passing over the land. The average tropical storm has the lifespan of 2 weeks.

Q

Tornadoes- Characteristics

A

Usually form in late afternoon, when warm humid air meets with cold dry air, often preceded/occur alongside high winds/heavy thunderstorms/hail, life span of few seconds to a few hours, average width is 660 feet, average speed of movement is 30 mph, they die within 6 miles on average

Q

How tornadoes form- wind shear, updraft, storm, supercell

A

(Wind Shear) Fast moving winds roll the air below into a horizontal vortex (a spinning tube) above opposing surface winds (Updraft) Air near the ground is warmed by the sun and lifts up, causing the horizontal vortex to become upright (Storm) The updraft creates two vortices. The stronger one becomes the heart of the thunderstorm and the other one dies (Supercell) Upper level winds tilt the mesocyclone (the rotating updraft) allowing the storm to grow, as warm air is sucked into the storm away form the cool air in the downdraft

Q

End of climatic hazards topic.

A

Yay.

22
Q

Name three types of skewed information

A

Personal bias, Outdated bias, News bias

23
Q

Name four types of (often incorrect) intuition

A

Things are getting worse, a hard barrier between rich and poor, rich then social, sharks are dangerous

24
Q

Describe what the population will look like at 2100

A

Fertility rate will average out at about 2 children per woman, better health leading to more surviving elderly, world population plateaus at 11 billion

25
Q

Describe the destiny instinct

A

The idea that innate characteristics determine the destinies of people, countries, religions or cultures, i.e. the belief that Africa will remain an LIC

26
Q

Describe the general trend of world population

A

Population increases very gradually over the years, high birth rate (due to lots of children needed for agricultural work, and due to high infant mortality rate), then in 1800s many countries have industrial revolutions, lifestyle goes up, health & medicine becomes better, life expectancy goes up, infant mortality goes down. This results in massive population growth. In 1900-2000 the population increases by almost 5 billion. Birth rate then begins to decrease, starts coming to slightly over 2, by 2100, the world will have plateaued at 11 billion

27
Q

Gapminder- the 4 income levels

A

Level 1- earn less than $2 a day, extreme poverty, Level 2- between $2 and $8 a day, where almost half of the population is, Level 3- between $8 and $32, Level 4- $32+

28
Q

Describe the gap instinct

A

The habit to generalize things into two separate, defined classes (whereas the reality is that the majority are generally in the middle

29
Q

What are the 4 rules of thumb that you can use to control the Gap Instinct?

A
  1. Most things improve 2. The most people are in the middle 3. First social, then rich 4. Sharks kill few

Q

Definitions: Human Development Index

Definitions: Life expectancy

A

The average number of years a person born in a particular country might be expected to live

38
