- 3. What is astronomy? Astronomy is the study of everything in the universe beyond Earth's atmosphere. That includes objects we can see with our naked eyes, like the Sun , the Moon , the planets, and the stars . It also includes objects we can only see with telescopes or other instruments, like faraway galaxies and tiny particles.
- 4. Astrology Astrology isthe study of the influence that distant cosmic objects, usually stars and planets, have on human lives. The position of the sun, stars, moon and planets have affects on human lives.
- 5. Pseudoscience Pseudo means“false” a collection of beliefs or practices mistakenly regarded as being based on scientific method.
- 6. Difference between Astronomyand Astrology Astronomy is a research based study of planets, stars, asteroids, galaxies and the properties and relationship of the celestial bodies. On the other hand, Astrology is the belief that the positioning of stars and planets affect the way events occur on earth.

- 9. Atmosphere: isthe envelope of gases surrounding the earth. The earth’s atmosphere is 10,000 kilometres long above the ground level. Sphere: means round in shape “Oblate spheroid” or ellipsoid: Earth’s spin around sun cause it to squashed at its poles and swollen at the equator. Equator: imaginary line around the middle of earth Orbit:
- 10. Earth’s equator TheEquator is an imaginary line around the middle of the Earth. It is halfway between the North and South Poles, and divides the Earth into the Northern and Southern Hemispheres.
- 11. Earth’s radius isthe distance from the center of Earth to a point on or near its surface.
- 12. Earth’s rotation The earthorbits the sun once every year that is equal to 365.25 days. https://clickv.ie/w/I4Ot Earth’s atmosphere https://www.brainpop.com/science/earthsystem/earthsatmosphere/ Earth’s structure https://www.brainpop.com/science/earthsystem/earthsstructure/
- 13. Seasons on earth Themost important factor that determines the season is the maximum intensity of sun’s rays over a given area. As Earth revolves around the sun on its tilted axis, season change. The positioning of subsolar point indicates the weather. For instance, the subsolar point moves north and south, indicating summer in the Northern or Southern Hemisphere.
- 14. What causes changein weather on north and south pole This illustration shows summer in the Northern Hemisphere. The Northern Hemisphere is tilted toward the sun, and the subsolar point is north of the Equator, where the sun’s rays hit the Earth at a right angle. The angel of sunlight decreases as you move away from the subsolar point. The angle of sunlight reaching the South Pole, for instance, is almost 0. there it is winter. As the Earth continues to revolve and the Southern Hemisphere tilts toward the sun, the Southern Hemisphere will experience summer.
- 15. Earth’s solstice andEquinox https://www.brainpop.com/science/earthsystem/solsticeandequinox/ What is equinox?
- 16. Spring and Autumnequinox The word equinox is Latin and means equality of night and day. The equinox points to the specific times usually two times when sun is located exactly above the equator. The Northerner and Southern Hemisphere have different dates for equinox. Northern Southern Spring equinox 21st March Spring equinox 22nd September Autumn equinox 22nd September Autumn equinox 21st March
- 17. Solstice The solstice(combining the Latin words sol for “Sun” and sistere for “To Stand Still”) is the point where the Sun appears to reach either its highest or lowest point in the sky for the year and thus ancient astronomers came to know the day as one where the Sun appeared to stand still. In the Northern Hemisphere, the June Solstice heralds the astronomical beginning of summer and is the day with the most daylight in the year. The winter solstice in December mark the least sunlight or the shortest day of the year.

- 20. The Moon (TeMarama) Some facts about Te Marama Earth’s natural satellite was formed about 5000 million years ago. Little over a quatar the diameter
- 21. The NewMoon is when the Sun and Moon are aligned, with the Sun and Earth on opposite sides of the Moon. The time of new moon varies by time zone.
- 22. Moon phases It takesaround 29.5 days to move through the eight Moon phases. In western culture, we divide the lunar month into four primary and four intermediate Moon phases. The New Moon is the first primary Moon phase. The next three are the First Quarter Moon (Half Moon), the Full Moon, and the Third Quarter Moon (Half Moon). In addition, there are four intermediate Moon phases; the Waxing Crescent Moon, the Waxing Gibbous Moon, the Waning Gibbous Moon, and the Waning Crescent Moon.
- 23. Full Moonis the most striking Moon phase when the entire face of the Moon is lit up.
- 26. Why can’t seethe new moon 1. The alignment of the Sun, the Moon, and Earth leaves the side of the Moon that faces Earth in darkness. This is called a conjunction or syzygy. 2. The New Moon is up in the daytime sky. It rises and sets around the same time as the Sun, bringing it too close to the Sun’s glare to be seen with the naked eye.
