The three reasons could be the following:
1) Relying on computers and not going to the field. Sometimes a technical or software fault could lead to a wrong prediction. it could be a new forecaster who does not know the weather patterns and so follows the computer model instead of stepping outside and actually feeling the weather
2) The atmosphere always changes with natural disasters occurring such as pollutants in the air that make forecasting difficult.
3) Most of the times meteorologists base their forecasts on probability. Because of differences in the climate, those temperatures are not the same, so errors occur.
The statement that is not one of the evidences of seafloor spreading is the distribution of ice sheets across the planet.
This evidence was obtained from the studies of the molten material, seafloor drilling, radiometric age dating and fossil ages, and the magnetic stripes.
Seafloor spreading often taakes place at divergent plate boundaries.
The spreading is known as a process that occurs at mid-ocean ridges and it is the point of new oceanic crust formation.

Answer:
The answer is D (the distribution of ice sheets across the planet)
Explanation:
Sea Floor Spreading Evidence
Harry Hess’s hypothesis about seafloor spreading had collected several pieces of evidence to support the theory.
So, the distribution of ice sheets across the planet is not evidence of sea-floor spreading.
