Removing ground water in mexico city is a problem because it causes
a. land to sink
b. disputes over water
c. floods to occur
d. droughts to occur

The correct answer is - a. land to sink.

Mexico City is a very city, it is fact the second largest city in the world. It's sheer size means that all the things built by the people are putting a lot of pressure on the land itself.

Considering the fact that Mexico City is built on a place where until relatively recently there was a lake is a big concern. The soil is very soft for starters, and also there's lot of groundwater reserves very close to the surface. By removing the groundwater, big gaps, empty spaces, inside the ground, and close to the surface, are opening. The soft sediments are not able to sustain the pressure, so the land is sinking.

temperatures get warmer — and heatwaves are more common. nothing says summer like warm weather. this rise in temperatures is caused by the tilt of the earth's axis. our planet doesn't sit perfectly straight as it spins — it has a slight lean of approximately 23.5 degrees with respect to the sun, called the axial tilt.
