To calculate the noon sun's angle above the horizon at Placerita Canyon, identify today's date and find the corresponding solar declination using the analemma. Next, calculate the arc distance (AD) by subtracting this declination from 34°N, and finally subtract the AD from 90° to get the solar altitude (SA). This gives you the sun's angle above the horizon at noon.
To calculate the angle of the noon sun above the horizon at a location of approximately 34°N latitude, given that the solar altitude (SA) is 90º minus the arc distance (AD). Start with the latitude of 34°N. Identify today's date and find the corresponding declination of the sun using the analemma. Subtract this value from 34°N (or vice versa depending on which is greater) for the AD. Finally, subtract the AD from 90° to get the SA.
For example, if today's declination of the sun was 23°N: AD = 34°N - 23°N = 11°, then SA = 90º - 11º = 79º. So, at noon the sun would be 79 degrees above the horizon at Placerita Canyon if today's date corresponds to a declination of 23°N.

Answer:
The latitude at which the noon sun is directly overhead is defined as the sun's declination. For example, if the sun appears directly overhead at 20°N latitude, the sun's declination is thus 20°N. Figure 7-3, known as analemma, shows the declination of the sun throughout the year. Thus, if you would like to know where the sun will be directly overhead on September 20, you can look on the analemma and find that it will be at 1°N. Given the declination, the noon sun angle at a particular latitude on any given day can be calculated.
Figure 7-3. The analemma, a graph illustrating the latitude of the overhead noon sun throughout the year.
Figure 7-4 shows that for each degree of latitude that the place is away from the latitude where the noon sun is overhead (declination), the angle of noon sun becomes one degree lower from being vertical (or 90°) above the horizon. Noon sun angle for any given latitude on any given day can be calculated using the following equation:
Noon Sun Angle = 90° - (Latitude +/- Declination)
In this equation, use " - " when the latitude and declination are on the same hemisphere and use " + " when they are on the opposite hemispheres. For example, on April 11, the declination is 8°N, the noon sun angle at Springfield, Illinois (40N) on April 11, therefore, should be 58° (90° - (40°N - 8°N).
Figure 7-4. Noon sun angle calculation. The example in this figure illustrates how to calculate the noon sun angle for a city 40° north of the equator (like Springfield, Illinois) on December 22.

Explanation:
Interventions that have been associated with a decrease in mortality and disease rates include exclusive breastfeeding, complementary feeding strategies, routine immunizations and vaccinations for children, preventative zinc supplementation in children, and vitamin A supplementation in vitamin A deficient populations.
------product of high updraft from clouds high in the sky where droplets are taken upward and collide with other droplets.
------Water droplets fall to the ground.
------falls as water. freezes on contact
____ice crystals fall
1. Rain 2. Sleet 3. Snow 4. Hail 5. Freezing Rain
Answer:
1- SLEET
2- HAIL
3- RAIN
4- FREEZING RAIN
5- SNOW
Explanation:
(1) Sleet- Sleet refers to the type of rain that forms very small ice crystals as it falls from the cold air. This cold air provides a much cooler temperature favoring in the formation of these crystals.
(2) Hail- When the ice pellets are allowed to scatter within the dense cloud, then the ice pellets combine with the water droplets present at a higher altitude. It then grows larger in size, and after this continuous motion of ice pellets, they fall back on the surface.
(3) Rain- It is the most commonly occurring precipitation and these raindrops are formed when the ice crystals in the clouds are melt.
(4) Freezing Rain- These are raindrops that usually gets freeze as they fall over the surface in a comparatively colder weather. After precipitation, the surface gets covered by these ice coatings.
(5) Snow- The ice crystals when it grows and gets accumulated in the clouds, they form snowflakes that are of variable shapes and sizes.
Hence the correct answers are being matched.

Answer:
With the population moving West, the old Northwest was made up of
d.Ohio, Indiana and Illinois.
Explanation:
Other states that made up the old Northwest were Michigan, Wisconsin, and a portion of Minnesota. New York, Pennsylvania, Cincinnati, and Virginia were never part of the old Northwest. The old Northwest was awarded to the United States after the 1783 revolutionary war. Geographically, the old Northwest included the land between the Great Lakes, the Mississippi River, and the Ohio River.
