If the earth's p-wave velocities were slower than they actually are, then their arrival times would plot higher on the travel time chart.
The new p-wave arrival time that matches a slower earth with the same mantle and core depths would be longer than the original arrival time. This is because slower velocities would mean that the seismic waves take longer to travel the same distance.
Therefore, the arrival time would be delayed and plot higher on the travel time chart. It is important to note that the arrival time is directly proportional to the velocity of the seismic waves. If the velocity is slower, the arrival time will be longer, and if the velocity is faster, the arrival time will be shorter.

Answer:
Gentrification.
Explanation:
Gentrification is the renewal and rebuilding of the urban environment, which takes place when wealthier middle-class people move to declining areas, displacing the lower-class people there. As a result of gentrification, the average family income in the community increases and the number of members decreases. This is believed to be due to the departure of poorer residents who are unable to pay the increased rent and other real estate and land taxes. Old industrial buildings are often converted into dwellings and shops. In addition, new stores and service facilities are moving to the area, serving a wider customer base. This in turn increases the attractiveness of the region for more affluent immigrants and reduces accessibility for the poorer. This process is often made possible by government-funded investments to improve local infrastructure, mortgages for poor and first-time home buyers, and financial bonuses for owners of dilapidated houses. Following the implementation of these economic measures, crime in the area tends to decrease and real estate prices and tax revenues rise.
ensure that fair prices are paid for import crops
B.
ensure that those who grow export crops receive fair compensation for their work
C.
export more than 50% of their crops to industrialized countries, such as the US
D.
grow crops on foreign-owned plantations
Fair trade producers are those which ensure that those who grow export crops receive fair compensation for their work.
The fair trade producers is a movement that created a system which ensures that growers of export crops are compensated in a fair way for their products. The fair trade producers advocate the payment of higher prices along with better social and environmental standards to exporters in developing countries. The movement concentrates mainly on products that are usually exported from developing countries to developed countries.
