Questions this course answers

What carries Saharan dust toward the Amazon?

Winds transport dust through the atmosphere; settling and rain filter the plume along the way.

Put this phosphorus path in order.

Arrival is only one step; bioavailability and local cycling still matter.

Why can phosphorus from dust matter to the Amazon without inventing the forest?

NASA’s comparable input and loss estimates sit inside a larger nutrient budget.
