Question

which statement explains what upwelling causes?
○ upwelling causes tides to rise and fall.
○ upwelling causes changes in the direction of currents.
○ upwelling causes nutrients, minerals, and tiny organisms to rise.
○ upwelling causes currents in the pacific ocean to change direction.

Explanation:

Upwelling is a process where deep, cold water rises to the surface. This water brings with it nutrients, minerals, and tiny organisms (like plankton). Tides are mainly caused by the gravitational pull of the moon and sun. Upwelling doesn't directly cause changes in the general direction of currents (like major ocean - wide current directions) or specifically in the Pacific Ocean's current direction.

Answer:

Upwelling causes nutrients, minerals, and tiny organisms to rise.
