Flashcard on Earth's Atmosphere

Front

What is barometric pressure?

Back

Barometric pressure is the pressure exerted by the weight of the atmosphere at a given point, typically measured in millibars (mb). A standard sea-level pressure is approximately 1013.25 mb.

Front

What happens to temperature as altitude increases in the stratosphere?

Back

In the stratosphere, temperature increases with altitude due to the absorption of ultraviolet radiation by the ozone layer.

Front

Which factor is not typically associated with weather?

Back

Weather patterns over time/years are not typically associated with weather; they relate to climate.

Front

In which layer of the atmosphere do meteors typically burn up?

Back

Meteors typically burn up in the mesosphere, which is located above the stratosphere.

Front

What important layer is contained within the stratosphere?

Back

The ozone layer is an important layer contained within the stratosphere, protecting the Earth from harmful ultraviolet radiation.

Front

What is the troposphere?

Back

The troposphere is the lowest layer of Earth's atmosphere, where weather occurs and where most of the atmosphere's mass is found.

Front

What is the role of the ozone layer?

Back

The ozone layer absorbs the majority of the sun's harmful ultraviolet radiation, protecting living organisms on Earth.

Front

What is the exosphere?

Back

The exosphere is the outermost layer of Earth's atmosphere, where atmospheric particles are so sparse that they can travel hundreds of kilometers without colliding with one another.

Front

How does humidity affect weather?

Back

Humidity refers to the amount of water vapor in the air, which can influence weather patterns, precipitation, and temperature.

Front

What is the significance of atmospheric pressure?

Back

Atmospheric pressure affects weather patterns, wind, and the ability of air to hold moisture, influencing climate and weather conditions.
