What are surface currents?
They are heat-driven occurences that carry ocean water horizontally across the ocean’s surface.
They are earth-driven currents that carry ocean water horizontally across the ocean’s surface.
They are water-driven occurences that carry ocean water horizontally across the ocean’s surface.
They are wind-driven currents that carry ocean water horizontally across the ocean’s surface.
What’s upwelling?
It’s the horizontal movement of water towards the oceans’ surface and pushes water away from an area.
It’s the vertical movement of water towards the oceans’ surface and pushes water away from an area.
It’s the vertical movement of water towards the oceans’ depth and pushes water away from an area.
Is the water that’s deep and cold forced to the surface by upwelling?
Yes
Maybe
No
What are some characteristics of deep cold water?
It’s rich in nutrients and supports large populations of algae, fish and other ocean organisms.
It’s poor in nutrients and supports small populations of algae, fish and other ocean organisms.
It’s low in nutrients and supports high populations of algae, fish and other ocean organisms.
What are gyres?

What causes surface currents?
Changes in density rather than wind
Wind
It carries or moves things around the world
When wind blows across the ocean’s surface and pushes water away from an area. Deeper colder water then rises to replace it
What causes upwelling?
Changes in density rather than wind
Wind
It carries or moves things around the world
When wind blows across the ocean’s surface and pushes water away from an area. Deeper colder water then rises to replace it
Why are ocean currents considered a “conveyor belt" ?
Changes in density rather than wind
Wind
It carries or moves things around the world
When wind blows across the ocean’s surface and pushes water away from an area. Deeper colder water then rises to replace it
