Explain how a storm becomes a cyclone.

Show answer Hide answer
Answer
Over warm oceans, rising moist air and the Earth's spin turn a storm into a cyclone.

Explanation

  • Warm ocean water heats the moist air above it, which rises.
  • Its water vapour condenses, releasing heat that warms the air further so it rises more.
  • This makes a very low-pressure area, and surrounding air rushes in and rises too.
  • The Earth's rotation makes the rushing air spin, forming a cyclone.
Rising warm moist air plus the Earth's rotation spins a storm into a cyclone.
