Question

1. what are katabatic winds?

a. gentle breezes over lakes
b. strong, cold winds descending from high elevations
c. hot, upward winds from deserts
d. warm currents in the ocean

Explanation:

Katabatic winds are defined as winds that flow downhill due to gravity, typically being strong and cold as they descend from high elevations (like mountains or plateaus). Option a is incorrect as lake breezes are different (like sea breezes, related to temperature differences between land and water). Option c describes upward (likely thermals or other desert - related upward air movements, not katabatic). Option d is about ocean currents, not winds. So the correct description matches option b.

Answer:

b. Strong, cold winds descending from high elevations
