           Section 1:  Earth in Space      

How does Earth move in space?

Earth has 2 major ways that it moves through space: Rotation and Revolution

The Earth spins on an imaginary line called axis. Earths axis is the center of the Earth and it runs north and south. The Earths axis is tilted at an angle of 23.5 degrees. It spins around on its axis is called rotation and as it rotates it causes day and night. Each rotation is 1 day. As Earth rotates around the sun, we call is revolution. It takes 365.25 days to finish 1 orbit and we call that 1 orbit 1 year.

What causes the cycle of seasons on earth?

Earth has seasons because it axis is titled as it revolves around the sun.Earth seasons depend on how the sun hits the Earth.

Section 2: Gravity and Motion

What determines the strength of the force of gravity between two objects?

The strength of the force of gravity between two objects depends on the distance between them. If mass increases force also increases. Gravity attracts all objects toward one another. If the distance increases the gravity decreases.

What two factors combine to keep the moon and earth in orbit?

Newton concluded that two factors-inertia and gravity- combine to keep the earth in orbit around the sun and the moon in orbit around the earth.

Section 3: Phases, Eclipse, and Tides.

What causes the phases of the moon?

The changing relative positions of the moon, Earth, and sun causw the phases of the moon, eclipses, and tides.

What are solar and lunar eclipses?

The phase of the moon you see depends on how much of the sunlit side of the moon faces earth. A solar eclipse is when the new moon blocks your view of the sun. A lunar eclipse is when the Earth

What causes the tides?

When the moons shadow hits Earth or Earths shadow hits the mo

Section 4: Earths moon

What features are found on the moons surface?

features on the moons surface include maria, craters, and highlands. Maria is a flat land and is very dark. Galileo thought that Maria was an ocean but actually it was hardened rock formed from lava flows from billions of years ago.

What are some characteristics of the moon?

The moon is dry and airless. Compared to Earth, the moon is small and has large variations in its surface temperature.

How did the moon form?

Scientists theorize that a planet sized object collided with Earth to form the moon.

you have some spelling mistakes like you pictures but take a look at the rubric and make you answers to the questions a little bit longer
