How do primary and secondary succession differ?
Primary succession starts on bare surfaces without soil (e.g., after a lava flow). Secondary succession starts where soil remains (e.g., after a fire).
100
What is the primary source of energy for atmospheric and oceanic convection?
The Sun
100
What is weather?
The condition of the atmosphere at a particular time and place.
100
A ___________ is a large, rotating storm that forms over tropical waters with wind speeds of at least 75 to 200 mph
hurricane
200
What natural events can trigger primary or secondary succession?
Primary succession can follow events like volcanic eruptions; secondary succession can follow fires, floods, or storms.
200
How does the Sun's energy affect the atmosphere?
It drives convection, producing winds.
200
The boundary between two different air masses with different temperatures.

What is the "eye" of a hurricane?
The eye is the calm, clear center of the hurricane with low pressure and light winds.
300
How can human activities trigger secondary succession?
Activities like deforestation or urbanization disrupt ecosystems, starting secondary succession in the cleared areas.
300
What role does convection play in the oceans?
It creates ocean currents.
300
The pressure is ______ when air rises and atmospheric pressure is less than the surrounding areas.
LOW
300
How does the interaction between warm and cool ocean currents impact tropical cyclone paths?
Warm currents can strengthen tropical cyclones, while cool currents weaken them; these currents, along with wind patterns, can also influence the direction and speed of the storm.
400
How does primary succession create new ecosystems?
Pioneer species grow on bare surfaces, creating soil over time, which supports plants and animals, leading to a diverse ecosystem.
400
What natural forces are created by convection in the atmosphere?
Winds
400
A front where warm air moves over cold air and brings drizzly rain and then are followed by warm and clear weather.
WARM FRONT
400
How do ocean temperatures influence the intensity of a tropical cyclone?
Higher ocean temperatures provide more heat energy, allowing the cyclone to intensify with stronger winds and heavier rainfall.
500
What are pioneer species, and why are they important?
Pioneer species are the first to colonize disturbed areas. They modify the environment, enabling other species to establish.
500
How do ocean currents form?
Through convection driven by the Sun’s energy.
500
A ________front is when a cold air mass moves in and pushes warmer air up, often causing sudden weather changes like thunderstorms or cooler temperatures.
COLD FRONT
500
What are the dangerous parts of a hurricane?
The dangerous parts include the high winds, heavy rain, storm surge, and the eyewall, where the strongest winds and most intense rain occur.
