VOCABULARY -

• astronomical unit : A unit of measure; 1 AU is the distance from

the Sun to Earth.

around another object

• revolution : the orbiting of an object around another object

around an axis

REVOLUTION VS. ROTATION

REVOLUTION

  • Orbiting of an object around another
    object

  • The MOTION of a planet around a sun
    or a moon around a planet

  • Orbit is the ellipitcal pathan object
    takes revolving around another object

media

REVOLUTION VS. ROTATION

  • The spinning of a celestial
    body (planet, moon, star)
    around an axis

  • Earth is tilted 23.5° on its
    axis

22

Reasons for Seasons

The main reason for seasons is the tilt of Earth's axis (NOT the distance to the sun). 


The Earth's axis is tilted by 23.5°

media

23

Seasons & Hemispheres

- At some parts of the year, the Northern hemisphere is tilted towards the sun, while the Southern hemisphere is tilted away causing different seasons.


- For example, when it is summer in the Northern Hemisphere, it is winter in the Southern Hemisphere (ref. image).

25

Direct & Indirect Sunlight

  • The earth is a sphere, so some parts of the earth receives 'direct sunlight', while other parts receives 'indirect sunlight'.

  • Direct sunlight is concentrated over a small area and results in more intense heat, while indirect sunlight is spread over a larger area and is less intense (ref. image).

media

26

Multiple Choice

What effect does the tilt of the earth have?

1

It changes the angle that the sun strikes the earth in different land areas

2

When the earth is tilted away from the sun we have night

3

It causes the earth to be farther away from the sun at different times of the year

4

When the earth is tilted away from the sun we have day

27

Multiple Choice

Which of the following best describes the tilt of the earth when it is summer in the southern hemisphere?

1

The northern hemisphere is tilted toward the sun

2

The northern hemisphere is tilted neither toward or away from the sun

3

The northern hemisphere is tilted away from the sun

4

Neither the northern nor the southern hemisphere is tilted towards the sun.

28

Multiple Choice

30

Multiple Choice

Question image
Why is it warmer in the summer?
1
Closer to the sun
2

3

4

31

Solstices

- Solstices occur twice a year, when the tilt of the Earth's axis is oriented directly towards or away from the sun.


- Winter solstice (and the shortest day in the NH): Dec. 21

- Summer solstice (and the longest day in the NH): Jun. 21

media

32

Equinoxes

  • Equinox literally means "equal night".

  • It occurs twice a year, and the Earth's tilt faces neither towards nor away from the sun.

  • Both hemispheres receives the same amount of sunlight. Day and night are the same length.

  • Spring equinox: March 21

  • Fall equinox: Sep. 21
