Answer to Question 1

Upwelling is the upward vertical movement of cold, nutrient-rich, and oxygen-rich water from beneath the pycnocline toward the ocean surface. Downwelling is the movement of warm, nutrient-depleted, and oxygen-depleted water from the ocean surface downward. Upwelling is associated with highly productive areas of the ocean, while downwelling is associated with low primary production.

Answer to Question 2

A cyclone is a spinning mass of low pressure air characterized by strong winds and heavy precipitation. Tropical cyclones form in tropical latitudes and are fueled by the warm water of low-latitude subtropical and tropical waters. A hurricane is a tropical cyclone that forms in the waters off of North and South America, whereas a typhoon is a tropical cyclone that forms in the western North Pacific Ocean.
