Explanation:
Mechanized culture uses plows to turn grasslands into farms
Climate changes so farms can no longer be sustained
Farmers migrate away
New irrigation technology brings farmers back
One critical aspect that affects population dynamics is the human - environment interaction which is mostly seen in farming activities.
Mechanized farming practices are not sustainable. They use a lot of nutrients in the soil and apply chemicals to crops to maximize outputs. Also farm machinery produce greenhouse gases that leads to global warming eventually climate change.
This can cause the occurrence of drought and farming is no longer possible. Farmers will emigrate from such an area in search for more arable lands.
Development of new irrigation technology is an incentive to bring farmers back into their abandoned farms.

Answer and Explanation:
A 1.5 earthquake on the Richter scale is 15 times stronger than a level 0 earthquake. This is because the Richter scale is a logarithmic scale making a number on the scale symbolize an intensity 10 times greater than the previous number on the scale.
An earthquake measuring 1.5 on the Richter scale has tremors that are captured only by seismographs.

the equation will be-
42+x=3(8+x)
42+x=24+3x

Answer:
Analyze the shape of the pyramid. What points of information from the pyramid stand out to you?
The pyramid has indeed the shape of a pyramid, although it is a bit narrow.
What stands out the most is that people younger than 24 still represent the age brackets with the largest share of the population. However, the difference is very small compared to the age brackets of people in adulthood.
People older than 60 still represent the smallest groups.
Compared to the population pyramid of 1965, what shifts in the world’s population do you notice?
The shape of the pyramid of 1965 was much broader at the bottom, this means that the lower age brackets represented a larger share of the world's population.
For example, the youngest group: those aged 0-4, represented in 1965, 14.3% of the world's population, while in 2015, they represented 9.1% of the world's population. This tells us that the world population is aging.
