EARTH

Earth is third from the Sun. There are possibilities for survival only. Not on other planets. Hence, there are only living things on earth.

• Earth's spatula is about 23 hours and 56 minutes.

• Daylight change occurs because of Earth's past. A part of the earth, ie, the day toward the sun will be day and night. (Eg) daylight in India The United States will be late at night when it will be.

• Astronomer astronomer Ariyapatri, who lived about 1500 years ago, scientifically explained that the earth itself is moving around.

• One day is calculated from 12:00 pm a day from 12:00 to midnight the next day.

• The time taken to take the Earth around the Sun is 365.24 days. That is why we calculate the leap year for 366 days. Only 29 days in February that year. Other days will be up to February 28 days. Leap year can be divided by only 4.

• The Baptist, who lived in the 16th century, said that the leap year is divided by 400, not even by 4. If the 1800, 1900, 2000, and 2100 are taken, the 2000 will be divided by only 400. Thus, the 2000 leap year.

• Earth's spin axis is 23 1/2 Degree leaked to the surface around the Sun. That is, the earth is 23 1/2 Degree slope on its axis. That is why seasonal change occurs.

• Surrounding the elliptical path when the Earth moves around the sun will be far from the sun in July and the most close in January. Therefore it is winter in July and summer in January.

• So, the whole earth should be summer or winter. But that does not really matter.

• The North is the winter season in December. At the same time it is summer.

• In the months of April and May, the North Ridge is cool when the North Ridge is cool. Because the earth is 23 1/2 Degree slope, this change occurs.

• Seasonal transition occurs because the earth is 23 1/2 Degree slope on its axis. It does not come around the sun.

• Earth's axis is a fictional line. The line drawn on the ground is not. The fictitious line of the earth is the axis of the earth's northern pole and the south pole.

• The sun rises at the maximum south-east point on December 22. From the day the sun rises to the north. Therefore, it is called the North Stream.

• The sun rises at the maximum northeastern point on July 21. From the day the sun rises to the south. Therefore, it is called the southern ridge.

• The days of march 21 and September 23 are day and night days. 12 hours a night and 12 hours a day.

• In the north half of the sun in June, the north will be six days continuously, and six months in the south pole.

• In the south half of the Sun in December, the South Pole is six months continuously in the northern hemisphere and six months in the northern hemisphere.

• It is celebrated as the winter festival in December of the Christmas Festival, as countries like England India are in the Northern Hemisphere. At the same time, countries in the Southern Hemisphere such as Australia celebrate the summer festival.

Day and night

• Solar light is only one side of the earth. So, on that page all the places are daylight. At that time, on the other side of the earth, So, there's night time. Night will change from day to night; Daylight will change from day to night.

• Because the Earth rotates through the North and South Poles. It's about 24 hours for the earth to rotate itself. At night, we get light from the bright stars and the moon.

Earth and season

• The earth itself is surrounded by itself; The Sun also comes around.

• The rotation of a rotating earth will be equal to daylight and night time when it is perpendicular to the direction of sunlight. Sun in the East Disappear in the west.

• In the summer, there is no more time than night time. The sun rises in the north and disappears in the northwest.

• In winter the nights are longer than night time.

• The sun rises in the south and southwest. The reason for this is that the rotating axis of the Earth is not at 90 Degree angles for the direction of sunlight.

New moon and Full moon

• Moon is the natural satellite in nature.

• The moon does not automatically light up the light. By reflecting the light from the sun, we can see the moon.

• The moon rotates itself about its axis. Earth is also around. Time for these two types of operations, ie 29.5 days.

• We can only see one side of the moon. You can not see the page again.

• When the moon is around the Earth, we can not see the moon when the sun is on the same side of the sky.

• Because the light that is reflected in the light does not come to us. This is the moon, we call the new moon.

• When the moon is around the Earth, we can see the moon when the Sun is in the opposite opposite.

• Because the light reflected by the light comes to us. This is the moon, we call the whole moon full moon, full moon moon
