Will the temperature of the descending air increase or decrease?

Assume that the relative humidity of the air is below 100% during its descent to the valley. At what rate will the temperature change? ____ $^{\circ} \mathrm{C} / 1000$ m

Compare and contrast the development of embryos in placentals and marsupials.

Will the temperature of the descending air (increase or decrease)? The temperature will _______________________.

At what rate will the temperature of the rising air change? _____________________________ $^\circ C$/$1000$ meters

Determine the air temperature and dew-point temperature of the rising air at the summit of the mountain. Temperature: ${ }^{\circ} \mathrm{C}$ Dew-point temperature: ${ }^{\circ} \mathrm{C}$

As the air moves up the windward side of the mountain, will it get cooler or warmer?

At what height will the rising air reach its dew-point temperature, causing the water vapor to begin to condense? ____ m

At what height will the rising air reach its dewpoint temperature and water vapor begin to condense? Rising air will reach dew point at ________ meters.

Is the air at sea level saturated or unsaturated?

Did dew or frost occur on either of the two days represented in the graph? If so, indicate the day and time and explain how you arrived at your answer.

Use Table 15.2 to determine the saturation mixing ratio, water-vapor content, and dew-point temperature of the air at sea level in Figure 15.10. Saturation mixing ratio: $\mathrm{g} / \mathrm{kg}$ of air Water-vapor content: $\mathrm{g} / \mathrm{kg}$ of air Dew-point temperature: ${ }^{\circ} \mathrm{C}$

Use Table 15.2 to determine the saturation mixing ratio, water-vapor content, and dew-point temperature of the air at sea level in Figure 15.10. Saturation mixing ratio: $\mathrm{g} / \mathrm{kg}$ of air Water-vapor content: $\mathrm{g} / \mathrm{kg}$ of air Dew-point temperature: ${ }^{\circ} \mathrm{C}$

On which day and at what time does the lowest relative humidity occur? Day: ___________ , time: __

Two planes leave Los Angeles at the same time. One heads south to San Diego, while the other heads north to San Francisco. the San Diego plane flies 50 mph slower than the San Francisco plane. In 1/2 hr, the planes are 275 mi apart. What are their speeds?
