11
multiple choice 5 points
wind and ocean currents are formed by ____.
radiation
condensation
conduction
convection

Explanation:

First Question (Convection Occurrence)

Convection is heat transfer via fluid (liquid/gas) movement. Solids have fixed particles, so conduction (direct contact) is dominant there. Liquids and gases can have bulk movement (convection currents), so convection occurs in them.

Wind and ocean currents form due to convection. Convection creates density differences (hotter, less dense fluid rises; cooler, denser sinks) leading to movement. Radiation is energy transfer via waves, condensation is phase change, conduction is direct heat transfer (not for large - scale fluid movement like wind/currents).

Answer:

D. liquids and gases
