By 1 degrees celcuis.
What are the first two stages to a tropical storm forming?
- Warm water evaporates l, rises and condenses, producing energy.
- Low pressure drives surface winds.
What are the last 2 stages to the formation of a tropical storm?
- Easterly winds move tropical storms west.
- Storms strengthen as they move over warm water.
What are 3 natural causes for climate change?
- Orbital changes
- Volcanic activity
- Solar output
What is a primary effect?
Immediate impacts caused by hazards
What is a secondary effect?
Effects that happen later as a result of primary effects.
