We are living at a planet called earth. Earth is a third planet from the sun. Earth has crust that depth is 0-35km, upper mantle that depth is 35-60km, mantle that depth is 35-2890km, outer core that depth is 2890 5100km and lnner core that depth is 5100-6378km and shape of earth is sphere.

Sun light will come from one side of Earth so that side will be bright but other side is

still dark so there day and night for example in this picture sunlight come from right so earth’s right place is bright so this place is day but left place is dark so this place is night.

1. What is the shape of the Earth

2. Why do we have day and night?

The reap year means a year that there is one day more than normal because actually there is 365,25 after 4 year 1 day will different so there is leap year to correct it and it also year there is Olympic.

Longitude is a line expands from East to West. This line is parallel to the Equator. London’s Greenwich Observatory is a place that Longitude’s 0 degrees. Latitude is a line that expands North to South. Equator is the place that Latitude’s 0 degrees. So difference between them is Latitude have 0 to 90 degrees but Longitude have 0 to 180 degrees and Latitude are horizontal lines that extend from East to West but Longitude is vertical line that expand from North to South.

3. What is meant by the leap year?

4. What is the difference between Longitude and Latitude?

Time zone is zones that decide time of places some small country have one time zone but some big country have more than one time zone. To link time zone to Longitude we need to know Longitude in degrees and when 15degrees difference from 0degrees 1 hour will difference so if London is Noon and place is 120degrees 8hour will be different.

Moon has phases because moon will orbits Erath and The Moon takes 27.3 days to orbit Earth, but the lunar phase cycle (from new Moon to new Moon) is 29.5 days.

5. How to link Longitude and Latitude to time zones?

6. What are the phases of the moon?

7. What is an eclipse? Eclipse is a phenomenon that sun and moon will overlap together.

It only happens sometime when the Moon passes between the Sun and the Earth. Eclipse will happen 2～4 times in a year but it not all of eclipse is total eclipse. Some year eclipse will happen 5 times and some year eclipse will not happen.

8. What is the meaning of the tide? Tide is the periodic rise and fall of the waters of the ocean and its inlets, produced by the attraction of the moon and sun, and occurring about every 12 hours.

9. What are the features of the moon’s surface? At the features moon’s surface will be so many craters because so many meteorite will hit moon’s surface.

10. What are the differences in seasons? The earth is rotates around the sun your particular area is either closer or farther away from the sun. The two sites below represent what each season's position is, relative to the sun as the earth moves in its orbit. It can make them change in boreal summer the northern hemisphere is tilted towards the sun, and in winter away from the sun.

11. Why is there night and day? Because the earth rotated around and during the night we are facing away from the sun, while during the day we face towards the sun. People on the other side of the earth experience day when we have night and the other way around.

12. What is the Earth’s position in the solar system? The position of the earth in our solar system is the third of the planet except for the sun so the order of the planet is like sun, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

13. Why we can see other planets? Because they are relatively close to the earth as compared to the stars you see at night. The planets are visible because sunlight is reflecting off of the planet’s surface. The other planets are covering in cloud except for Venus so Venus is the brightness. If you want to see other planets you have to use the microscope such as Mars, Jupiter, and Saturn.

I can see beautiful star and planet.

14. What is the exploration of mars? Since 1960, the Russian and American space agencies have sent many spacecraft to mars especially after a quiet decade, Mars exploration took off again with the Mars Observer mission launched in 1992. Unfortunately, this spacecraft was lost due to explosion! NASA's MRO was launched in August 2005 and went into orbit around Mars in March 2006. It is making very detailed maps of the Red Planet. Those maps will help scientists select landing sites for other future missions. The Phoenix Mars Lander was launched in August 2007. It landed near the North Pole of Mars in May 2008.

15. What does the life cycle of a star? The large stars have a little life than the small stars. The bigger star can burn helium others burn carbon some even burn oxygen this is all based off the core temperature the hotter the more the more elements it can burn.

Chapter16: What is our position in a galaxy? We are thousands of light years from the center of the universe. The solar system orbits around the center of the Galaxy. We are about a 100 light years away from the center.

Chapter17: How many distances between stars and galaxies? The distances involved in galaxies are huge. The distance from one star and another in a galaxy is millions of times more than the distance between the planets in the solar system. Meanwhile, the distance from one galaxy to another is millions of times more than the distance between the stars in a galaxy. The volume of the universe is 40 billion trillion cubic light-years. Dividing this into 170 billion galaxies gives us one galaxy per 2.35 billion trillion cubic light-years. Taking the cube root of 2.35 billion trillion, we get an average distance of 13.3 million light-years between galaxies. Keep in mind this is offset by the distances between galaxy clusters. The distance between Andromeda and the Milky Way is only 2.5 million light-years.
