Concept:Earth’s rotation creates the day-night cycle and distributes heat, making the planet habitable. Without it, life as we know it could not survive.
Explanation:The rotation of Earth on its axis gives us alternating day and night. This cycle prevents any one side from becoming too hot or too cold. If Earth stopped rotating, one half would always face the Sun, baking in continuous daylight, while the other half would remain in endless darkness, freezing. Extreme temperatures would develop — scorching heat on the lit side and bitter cold on the dark side. Such harsh conditions would make it impossible for most life forms to survive. Rotation also helps move ocean currents and wind patterns, which regulate global climate. Without it, weather systems would break down. Seasonal changes, however, are caused by the tilt of Earth’s axis, not by rotation. Therefore, option A is incorrect. Options C and D are also wrong because, without rotation, there would be no cycle of day and night at all — not simply shorter or longer days.
Answer:B. Life would not have been possible on the earth.
