changes in gravity
What is the upward movement of cold water from the ocean depths called?
La Nina
Upwelling
Global warming
El Nino
Imagine two planets. Planet A is completely covered by an ocean, and has an overall average albedo of 10%. Planet B is blanketed by clouds, and has an overall average albedo of 80%. Which planet reflects more sunlight back into space?
Planet A
Planet B
the two planets reflect the same amount of light

Order these three surfaces - grasslands, fresh snow, and asphalt from highest albedo to lowest albedo.
snow--> asphalt --> grasslands
asphalt --> grasslands --> snow
snow --> grasslands --> asphalt
grasslands --> snow --> asphalt
grasslands --> asphalt --> snow
In class we learned about the possiblity of slowing of deep water currents. What would be the main cause of the slowing?
The density of the ocean water being decreased near Greenland
El nino warming the surface waters of the Pacific Ocean
