All of the following are examples of how geographical boundaries can limit cultural interaction except rivers
Explanation:
Rivers have historically been the reason of a lot of cultural exchange and not barriers to it due to many reasons.
The primary reason is that there is more chance of civilizations and settlements to happen near a river because of its rich nutrient soil and ready supply of fresh water to drink.
The other is the human ability to cross the water easily making it easy for the people to navigate it and meet people across.
The third reason is that the navigation downstream is how civilizations have historically expanded territory.
Thermal inversion.
A thermal inversion forms when a warm layer of air traps a cooler layer of air close to Earth's surface. The cold air ends up at the surface when the mountains block the morning sunlight from warming the floor of the valley or particulate pollution blocks sunlight from reaching the surface.
The increased aerosols in the urban atmosphere reduce the incoming solar radiation and increase the atmospheric longwave radiation in the urban areas. The response of the surface to the change of absorbed radiation is strong at night and weak during the day.
The warm air above cooler air acts like a lid, suppressing vertical mixing and trapping the cooler air at the surface. As pollutants from vehicles, fireplaces, and industry are emitted into the air, the inversion traps these pollutants near the ground, leading to poor air quality.

It depends on the type of the speech. If it is a short, impromptu or unimportant speech, there is no problem in displaying the aid.
