There's four stages in the classical demographic transition model:
Stage 1 - Pre-transition
In this stage, the birth rates are very high, but also the life expectancy is very low, thus the growth of the population is slow.
Stage 2 - Early transition
In this stage, the birth rates are very high, but the life expectancy is increased, so the population grows rapidly.
Stage 3 - Late transition
In this stage, the birth rates decline slightly, and the life expectancy is a bit higher, thus the population growth is slowing down.
Stage 4 - Post-transition
In this stage, the birth rates are declined significantly, the life expectancy is pretty high, so the population is either growing very slowly, or it is declining.
Answer:
surfaces of uniform composition
Explanation:
- Air Mass is a volume of air characterized by temperature and water vapor content and stretched for 100 kilometers.
- Classified according to the latitude and the source regions, like cold air mass found in cooler polar regions and warm masses form over the hotter and drier regions of continents and maritime air mass are found at the seas and oceanic masses.
- As air mass differs based on there densities they have humid and temperature conditions and can be modified in various ways, an increase or decrease of temperature is also affected by the large scale environmental conditions.
Answer:
since water takes a long time to heat up and a long time to cool down, land masses along these coastal regions have more moderate temperature ranges than those of land masses inland on the same latitude
Answer:
b. The death toll from volcanic eruptions do not always correlate to exclusivity, and can be affected by human actions before and after the eruption.
Explanation:
Many volcanic eruptions don't kill anyone. This is because most active volcanoes are well-known to local residents, who give them appropriate respect.
Lahars are deadly, but so are pyroclastic flows, and releases of ash and/or poison gases. The two deadliest eruptions in recorded history caused death by starvation and tsunami.
The point of the paragraph was that the VEI was <em>not</em> directly related to the number of deaths.
