Glaciers, weather, and water shape earth by a. tectonics b. erosion c. el nino d. hibernation

Erosion is the answer, because water does not cause El Nino.  Also it is not possible for glaciers, hibernation, and tectonics to occur in water. Tectonics are types of plates.

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.
