What term describes the pressure exerted by the atmosphere at a given point?

The correct term that describes the pressure exerted by the atmosphere at a given point is "Atmospheric Pressure." This term specifically refers to the force per unit area exerted on a surface by the weight of the air above that surface. Atmospheric pressure is a critical factor in weather and aviation, as it influences wind patterns, temperature, and overall weather conditions.

While "Barometric Pressure" is often used interchangeably with atmospheric pressure, it specifically refers to the measurement of atmospheric pressure using a barometer. Hydrostatic pressure pertains to the pressure exerted by a fluid at rest due to the weight of the fluid above it and is not limited to air, making it less applicable in this context. Environmental pressure can refer to various pressures in the environment but is not a standard term for atmospheric pressure. Thus, "Atmospheric Pressure" is the most precise answer for the definition provided in the question.
