I was asked on a science exam how wind is considered solar energy. Please help.
Your instructor is including the effects of solar energy. The sun heats the earth which causes the air to rise and cause air movements. These movements are called winds. These winds contain kinetic energy. At this point, I believe your instructor would be satisfied, but I’ll complete the last leg of this logic. This kinetic energy can drive a wind turbine to into mechanical energy to generate electrical energy. I would categorize it as renewable and call it good.

Thermal energy from solar radiation excite the gasses our the atmosphere, and has much influence on the weather as well.

think about how wind is created.

It is quite true for wind to be considered as solar energy.The ground heats up faster than the sea,causing the air above it to get heated and rise up(this happens because the density of air decreases).To fill this space,cool air from the sea moves towards the land causing wind.Similar phenomenon can be observed on land also,where air moves from cooler part of the earth.

wind is considered as solar energy because wind is a renewable sources of energy and is not limited.

All forms of energy on Earth are essentially solar, except for geothermal.
The obvious one we think about when we talk about solar power is energy that is derived from solar panels; but wind is generated by heating and cooling of the air, which is caused by the sun.
A fire generates energy from burning wood (generally) from a tree that grew because of the sun.
Hydroelectric power is generated from the motion of water through the hydrologic cycle which is caused by the sun.
Tidal power can harness the energy of the tides, and the tides are caused by what? The pull of the sun and the moon on the Earth.
Even the burning of fossil fuels is ultimately solar energy because coal and oil are the remains of ancient carbon-based life forms which lived on Earth because of the sun.
