Answer:

This is your project soory I can't help you but I can give you hint that In one year earth takes rounds across sun or on it axis. so you are asked to mention those phases and paste picture in scrap book

Answer:

ok

Explanation:

1) In 1 Pg wrote name ,class , section , topic , and subject.

2) in 2pg draw index.

3) after index write information.

this are the I formation

  • Earth’s Revolution
  • For Earth to make one complete revolution around the Sun takes 365.24 days. This amount of time is the definition of one year. The gravitational pull of the Sun keeps Earth and the other planets in orbit around the star. Like the other planets, Earth’s orbital path is an ellipse so the planet is sometimes farther away from the Sun than at other times. The closest Earth gets to the Sun each year is at perihelion (147 million km) on about January 3rd and the furthest is at aphelion (152 million km) on July 4th. Earth’s elliptical orbit has nothing to do with Earth’s seasons.During one revolution around the Sun, Earth travels at an average distance of about 150 million km. Earth revolves around the Sun at an average speed of about 27 km (17 mi) per second, but the speed is not constant. The planet moves slower when it is at aphelion and faster when it is at perihelion.The reason the Earth (or any planet) has seasons is that Earth is tilted 23 1/2oon its axis. During the Northern Hemisphere summer the North Pole points toward the Sun, and in the Northern Hemisphere winter the North Pole is tilted away from the Sun.

  • Earth’s Rotation
  • Description of relations between Axial tilt (or Obliquity), rotation axis, plane of orbit, celestial equator and ecliptic. Earth is shown as viewed from the Sun; the orbit direction is counter-clockwise (to the left).Imagine a line passing through the center of Earth that goes through both the North Pole and the South Pole. This imaginary line is called an axis. Earth spins around its axis, just as a top spins around its spindle. This spinning movement is called Earth’s rotation. At the same time that the Earth spins on its axis, it also orbits, or revolves around the Sun. This movement is called revolution.A pendulum set in motion will not change its motion, and so the direction of its swinging should not change. However, Foucault observed that his pendulum did seem to change direction. Since he knew that the pendulum could not change its motion, he concluded that the Earth, underneath the pendulum was moving. An observer in space will see that Earth requires 23 hours, 56 minutes, and 4 seconds to make one complete rotation on its axis. But because Earth moves around the Sun at the same time that it is rotating, the planet must turn just a little bit more to reach the same place relative to the Sun. Hence the length of a day on Earth is actually 24 hours. At the equator, the Earth rotates at a speed of about 1,700 km per hour, but at the poles the movement speed is nearly nothing.

  • The Earth Moves Two Ways
  • The earth moves two ways. It spins and it moves around the sun. The spinning of the earth is called rotation. It takes the earth abut 24 hours, or one day, to make one complete rotation. At the same time, the earth is moving around the sun. This is called a revolution. It takes a little over 365 days, or one year, for the earth to make one full revolution around the sun
  • Earth's Tilt
  • The rotation and revolution of the Earth does not cause our seasons. You must add the tilt of the earth.
  • Imagine a spinning top, with it spinning straight up and down. Now, imagine the top tilted to one side. As the earth spins, it also tilts. It is because of this tilt that we have seasons. This will change how high the sun will get in the sky.

  • As the Earth revolves around the sun, its axis is tilted from perpendicular to the plane of the elliptic by ~23.45 degrees. It is on this axis that the earth rotates every 24 hours. Since the axis is tilted, the effects of revolution of the Earth is different for different parts of the globe.
  • Certain areas are tipped towards, or away from, the sun at different times of the year. This tilting causes the four seasons of the year. This tilting also creates opposite seasons in the Northern and Southern Hemispheres
  • The Earth's seasons are not caused by the distance from the sun, but rather, by the tilt of the Earth's axis. Summer is warmer than winter because the sun's rays shine more directly than during winter, and also because the days are longer than the nights. During the winter, the sun's rays hit the Earth at a steeper angle, producing shorter days.
  • The equinoxes are days in which day and night are of equal duration, while the solstices are the days when the sun reaches its farthest northern and southern declinations, creating both the shortest and longest day of the year.

you can stick IMG of earth rotation and evolution.
