Population Pyramid
What pyramid has a wide base, narrow top, shows high fertility and lower life expectancies due to lack of healthcare and sanitation. This can be caused by a lack of women education and lack of contraception.
Expansive Pyramid
Weather and climate, water supply, vegetation and natural threats, raw materials/natural resources, are all examples of what factors influencing population density
Environmental Factors
How many significant figures in the number 0.0054.
2 sig figs
Explain the 3 reasons for the ozone hole over Antarctica?
The freezing temperatures slows molecule movement, the Polar Vortex causes low pressure at the Earth poles holding more chlorine gas, and Polar Stratospheric Clouds causing reactions that create chlorine gas
Describe the causes of the greenhouse effect?
The greenhouse effect can be caused by combustion of fossil fuels releasing CO2 into the atmosphere, cattle and rice farming which releases methane into the atmosphere, and the disposal of waste in landfills releasing for CO2 and methane
What pyramid has elderly and shrinking populations, taper in at the younger ages at the bottom, stable bulge in the middle, has a good aging population and stable working class.
Constrictive Pyramid
How does the birth rates in a LIC compare to the birth rates in a HIC.
Increase of birth rates in LICs compared to HICs, families try to have children survive into adulthood to harvest crops, care of older population, because at high infant mortality rates and lack of available contraception.
The equation, [young population (0-14) + old population (65+)] x 100 / middle population (15-64) is used to find what.
Dependency Ratio
How does photochemical smog form?
Nitrogen oxides from vehicles chemically react with VOCs in the atmosphere, with the addition of UV rays, all reacting to create photochemical smog
Describe 3 of the effects of climate change?
Increasing temperatures demonstrated by record heat are effecting the oceans, weather, and plants or animals. There is also rising sea levels due to melting ice sheets and thermal expansion. It has also caused decreased crop yield as there has been an increase in pests and loss of habitats.
State 3 things a negative growth country can do to increase the population of the younger age groups to become more stable.
Incentives for population growth, wider access to healthcare, and limit of contraception.
The policy used to manage population and decrease its effects on the planet. Promote sustainable human settlement development, change consumption patterns, changes in fertility, migration, mortality and promote improved human health.
United Nations Agenda 21
Independent variable on the x-axis and dependent variable on the y-axis, labelled with the physical quantity and appropriate unit, made up of narrow blocks of equal width that does not touch with a title is describing what chart.
Bar Chart
Identify the layers of the atmosphere and how temperature correlates to that layer as altitude ascends?
The lowest layer is the troposphere, in which temperature decrease, then is the stratosphere which temperature increases, then the mesosphere which temperature decreases, and finally the thermosphere which temperature increases up to 2000 C
What are the primary concerns of Solar Radiation Management?
Extreme regional cooling, impacts on local weather, and changes in precipitation patterns
Why are there usually more females in the older age groups compared to males.
Females have less risk, less risk in jobs and being in less labor-intensive fields, and more health aware.
How does improved education and opportunities for women effect LICs.
Decreased population growth because of increased higher education for women and delayed marriage and childbirth. Boosting household incomes and allowing more women in the workplace.
What order should you include the date in a pie chart.
From greatest percentage to lowest percentage.
Provide and explain 2 strategies to help maintain photochemical smog?
Firstly, reducing emissions, which can be done by scrubbers which eliminates SO2 from gases leaving industrial chimneys or catalytic converters which lowers NOx emissions from exhaust systems. Another solution is legislation, which include the Clean Air Act, which places caps on SO2 emission and creates more guideline to help reduce NOx.
What is the enhanced greenhouse effect?
When human activities like burning fossil fuels increase the greenhouse gases in the atmosphere causing the reactions with gases to trap extra heat, causing Earth’s temperature to rise.
