Which of the following is the most often cited environmental benefit of the eat-local movement?
a. Less fossil fuel is used in transporting food to market.
b. Fewer pesticides are used by farmers.
c. Less topsoil is lost to wind and water erosion.
d. There is less demand for chemical fertilizers.
e. It helps local and regional economies.
Answer:a
Explanation: the other answer choices aren’t universal and can be different for each farm.
The most often cited environmental benefit of the eat-local movement is that less fossil fuel is used in transporting food to market. Thus, the ideal selection is option a.
What are the environmental benefits of buying local products?Through reduced food miles or even transportation of any other goods, shopping locally can help reduce carbon emissions and air pollution. Additionally, to benefit the local economy, it is beneficial for the environment.
When food is produced and consumed locally, it reduces the need for long-distance transportation, which in turn reduces the amount of energy and fuel required to transport food. This leads to a reduction in greenhouse gas emissions, which can help to mitigate the impacts of climate change. While the other options listed may also be environmental benefits of the eat-local movement, they are not typically cited as frequently as the reduction in fossil fuel use.
Thus. the ideal selection is option a.

Explain how scientists use seismic data to learn about the geologic activity and happenings in the earth's interior
Answer:
Explained below
Explanation:
In physics, we know that waves usually change direction when are refracted or when they penetrate layers with different densities.
Therefore, when a seismic wave penetrates penetrates the boundary of the earth's interior, part of it will be sent back and part will be transmitted into the medium as refraction occurs. When we record the reflected and refracted ray, it enables the calculation of the position of major boundaries in the Earth's interior. This also helps in providing information about the solid & liquid character as well physical properties of the various layers in the medium.
