Weather Test Review

Front

What happens to air temperature and air pressure as a balloon rises through the troposphere?

Back

As a balloon rises through the troposphere, both air temperature and air pressure generally decrease.

Front

What weather condition occurs when air temperature equals the dewpoint?

Back

Fog occurs when the air temperature is equal to the dewpoint.

Front

What is an isotherm?

Back

An isotherm is a line on a weather map that connects points of equal temperature.

Front

How do you determine the dewpoint from air temperature and relative humidity?

Back

The dewpoint can be calculated using specific formulas or tables that relate air temperature and relative humidity.

Front

What is the dewpoint when the air temperature is 28°C and the relative humidity is 47%?

Back

The dewpoint is 16°C.

Front

What is relative humidity?

Back

Relative humidity is the amount of moisture in the air compared to the maximum amount of moisture the air can hold at that temperature, expressed as a percentage.

Front

What is the relationship between temperature and air pressure in the troposphere?

Back

Generally, as temperature increases, air pressure decreases in the troposphere.

Front

What weather phenomenon is likely to occur with high relative humidity?

Back

Fog or precipitation is likely to occur with high relative humidity.

Front

What is the significance of the dewpoint in weather forecasting?

Back

The dewpoint indicates the moisture content in the air and helps predict weather conditions like fog and precipitation.

Front

What does a weather map showing isotherms indicate?

Back

A weather map showing isotherms indicates areas of equal temperature across different locations.
