Brown haze near cities is often caused by air pollution from vehicle emissions, industrial activities, and burning of fossil fuels. These pollutants can react with sunlight to form ozone and other smog-forming compounds, creating the brown haze that hangs over urban areas. Factors such as weather patterns and geography can also contribute to the buildup of this haze.

What causes heat shimmer?

Heat shimmer, also known as heat haze, is caused by the refraction of light due to temperature gradients in the air. When the air near the ground is significantly warmer than the air above it, the light passing through these layers of air gets refracted and distorted, creating the shimmering effect that we see.


What movement causes an electric current in a wire?

The movement of electrons in a wire causes an electric current to flow. This movement can be initiated by various means, such as connecting the wire to a power source or moving a magnet near the wire.


What Waves change direction as they near shore because?

Waves change direction as they near shore due to the interaction between the wave front and the sea bottom. This interaction causes the wave to slow down and bend, resulting in the wave refraction. Refraction causes the wave energy to focus on headlands and disperse in bays, affecting wave direction.


Is the pushing or pulling force that exists when a magnetic material is near?

The force that exists when a magnetic material is near another magnetic material is known as magnetic attraction. This force causes the materials to be drawn toward each other.


What process occurs when an object vibrating at or near a resonant frequency of a second object causes the second object to vibrate?

This is called resonance. When an object vibrates at or near the resonant frequency of a second object, it causes the second object to absorb energy and vibrate with greater amplitude. This phenomenon can lead to amplification of the vibrations and sometimes structural damage if not controlled.
