Hurricanes
What’s the difference between a hurricane, cyclone, typhoon?
How hot does the water need to be in order for a hurricane to start?
What are the two main ingredients to make a hurricane? Relative to the equator, where do they always start? What else does a hurricane need to form? What does the inside of the storm look like? How are hurricanes related to tropical storms and
depressions? What is a storm surge? And why is it so dangerous?

climate change? How are greenhouses gases released into the
atmosphere? What is the “primary effect” of greenhouse gases
on the environment? …”secondary?” …”tertiary?” …
Name some of the fossil fuels that we burn to create our energy.
Greenhouse gasses &
Global Climate Change Name the more common greenhouse gasses in
order of most abundant to least abundant. List some of the ways that methane is formed? How do we know that climate change has
occurred in the past? And how can we predict its effects in the future?
Describe how has the concentration of carbon dioxide on Earth has changed over time?
