Question

what does the ocean conveyor belt affect?
a. global movement of warm and cold water
b. wind patterns only
c. ocean salinity
d. only arctic temperatures
frost melt in spring provides polar ecosystems with what essential element?
a. warm air
b. water
c. wind
d. ice

Explanation:

First Question:

The ocean conveyor belt (thermohaline circulation) is a global system of ocean currents that transports warm and cold water across the globe. Option a matches this description. Option b is incorrect as it affects more than just wind patterns. Option c: while salinity influences the conveyor belt, the belt's main effect isn't salinity. Option d is incorrect as it affects more than just Arctic temperatures.

Frost melt in spring turns frozen water (frost) into liquid water. Polar ecosystems need water, and melt provides this. Option a: Frost melt doesn't provide warm air. Option c: Wind isn't provided by frost melt. Option d: Frost melt reduces ice, it doesn't provide ice.

Answer:

a. Global movement of warm and cold water
