How do Cyclones and Tropical Cyclones connect
Cyclones and Tropical Cyclones both form over water but Tropical Cyclones form over subtropical waters.
How do Hurricanes and Typhoons connect
They are both tropical cyclones, but Hurricanes form over multiple oceans whereas Typhoons only form over the Northwest Pacific.
Where do Hurricanes form
North Atlantic Ocean Northeast Pacific Ocean Central North Pacific Oceans
What are the different wind types
Local Winds, Land Breezes, Sea Breezes, and Global Winds
Land Breezes
Land to water at night
Sea Breezes
Water to land in the day
Global Winds
Cold air falls at the poles. Warm air rises at the equator
What affects the motion of wind and ocean currents
Temperature - Energy provided by the sun Rotation of the Earth - Areas near the equator move more than those at the poles
What criteria do we use to describe wildfires
Burn Area, Fire Intensity, and Fire Containment
What causes wildfires
Main Cause (85%) - Human activity Other (15%) - Natural causes like lightning strikes.
What is Convection
When warmer less dense material rises causing it to cool and become denser making it fall (creating a cycle).
How does convection apply to the Hydrosphere
Convection causes ocean currents
How does convection apply to the geosphere
Convection causes continental Drift
How does convection apply to the atmosphere
Convections cause cooler winds to move down to the equator causing it to heat up and move up to the poles causing it to cool down creating a cycle.
