Wind and current are both forms of movement, but they move different things:

* Wind is the movement of air. It's caused by differences in air pressure, with air flowing from areas of high pressure to low pressure.

* Current is the movement of water, usually in a large body like an ocean. It's caused by various factors like tides, wind, and differences in water density.

Here's a table summarizing their similarities and differences:

| Feature | Wind | Current |

|---|---|---|

| What moves? | Air | Water |

| Cause | Air pressure differences | Tides, wind, density differences |

| Effect | Can move objects, influence weather, generate power | Can move objects, transport nutrients, influence weather |

Although their causes and what they move are different, they both play crucial roles in the environment and influence the planet's climate and ecosystems. They can also be used for human purposes, like wind power and ocean currents for transportation and energy.
