10. Use your lecture notes or text to define the following as they pertain to earth/sun relationships: Subsolar point Solar altitude: Declination of the sun: Insolation: 11. For each of the following dates, circle the location that would experience the longer period of daylight for that day. DATE Today (insert date) 12/1 LOCATION 1 Boulder 30° S 40° s 5° N 0° LOCATION 2 Mexico City 15° N 20° S 50° S 80° N 10/31 7/4 12. Today, are the varying lengths of daylight vs. night that are occurring around the world becoming more equal or less equal than they were yesterday? Explain.Explanation / Answer
Q10) ANSWERS
- Subsolar Point:- On a planet subsolar point is where its sun is generally recognized to be directly overhead i.e, where the sun's rays are striking or hitting the planet exactly perpendicular to its surface.
- Solar Altitude:- As far as the Solar altitude is concerned it refers to the angle of the sun relative to the Earth's horizon. We measure solar altitude in degrees because it is an angle. Based on the time of day, year and the latitude on earth, the value of the solar altitude varies. As we know the regions which are close to the equator have a higher solar altitude than regions which are near the earth's poles.
Sun: Sun is star, huge ball of fire made up of gases, provides light and heat for the earth and thus is the the ultimate source of energy for the solar system.
- Insolation:- It is the amount of solar radiation (radiant energy emitted by the sun from a nuclear fusion reaction) which hit or strikes a particular area of earth. Insolation affects the temprature thats is more the insolation, the higher the temprature.
