Let’s Get Started--LessonThe seasons are caused by the tilt of the Earth's rotational axis away ortoward the sun as it travels through its year-long path around the sun. TheEarth has a tilt of 23.5 degrees, and is often represented as an imaginary linethrough the Earth.

LessonWhat do you remember learning about seasons and how the Earthexperiences seasons throughout the year? Answer these questions ona piece of paper.1. When it is winter in Kansas City, Missouri, what season is it inMelbourne, Australia? Why?2. Does every place on Earth experience the same season at the sametime? Why?3. How long does it take the Earth to orbit the Sun?

Lesson--Correct AnswersWhat do you remember learning about seasons and how the Earthexperiences seasons throughout the year? Answer these questions ona piece of paper.1. When it is winter in Kansas City, Missouri, what season is it in Melbourne, Australia?Why? Kansas City is in the Northern Hemisphere. Melbourne is in the Southern Hemisphere. Theyexperience “opposite” seasons because when one hemisphere is leaning toward (summer) the Sun,the other is leaning away (winter) from the Sun.2. Does every place on Earth experience the same season at the same time? Why? No. Theearth’s tilt toward or away from the Sun determines the season, combined with the location of theEarth in its’ orbit around the sun.3. How long does it take the Earth to orbit the Sun? 365.25 days

Lesson--continuedBefore watching the video, write down your understanding about thedistance the Earth is from the Sun and how distance affects seasons.DOES THE DISTANCE BETWEEN EARTH AND THE SUN CAUSEEARTH’S SEASONS?It is a common misunderstanding that seasons occur because of Earth's elliptical orbit aroundthe Sun, with winter occurring when Earth is farthest away from the Sun, and summer when itis closest to the Sun. However, Earth’s distance from the Sun has little effect on the seasons asthe distance variation is only about 3%.

Level 7 Theory Intermediate Theory Leading-tone Diminished 7th Chords 1. Name the key and write the functional chord symbol for each diminished 7th chord. 2. Write diminished 7th chords using the key signature and accidentals. 3. Write diminished 7th chords using accidentals. 4. o7Identify each chord as diminished 7th (vii ) or dominant 7th (V7).

The dominant 7th scale that is created is also known as the mixolydian mode. There are corresponding scales for each of these 7th chords. The major 7th chord generally By lowering the 3rd and the 7th, we create a scale that corresponds to the minor 7th chord. This minor 7th scale is also known as the dorian mode .

the welfarist objective assumed in modern Mirrleesian theory. In normative terms, the shift from the classical bene–t-based view to the dominant modern approach, which pursues so-called "endowment taxation," is quite substantial. Under the modern approach, an individual s income-earning ability is taken as a given, and as ability makes it .
