The depth below Earth's surface at which the boundary between Earth's
outer core and stiffer mantle is located is 3. 2900 kilometers. This is
the location where the outer core that covers our planet ends and meets
its mantle that can be found within the Earth and is stiffer than the
very center of the planet which is made of iron.
This is called orbiting!
For an example: "The earth is orbiting the sun!"
I hope i helped :D

Answer:
Humans using water to generate electricity does not negatively affect groundwater.
Explanation:
Rainwater, which is mostly fresh, drains into sewers most of the time of course. They are abundant in many towns, cities, etc. As a result, rainwater is not utilized enough, as it goes to waste when blending in with dirty sewer water. This leads to rainwater not draining into aquifers, And with the worlds population increased rapidly by the minute, consumption increases, leading to the water contained within aquifers to decrease in amount. Runoff from things such as pesticides and fertilizers is also a major issue that harms groundwater. As rain approaches, these chemicals can seep through dirt and soil, eventually going as far as to reach the groundwater underneath the surface, contaminating it. And humans utilizing water to generate electricity is more of a benefit to the environment. It is another effective way to get power, and is an alternative to fossil fuels. And using groundwater as a power source does not really affect the groundwater itself, so this is why the last option is correct.
