How does Earth move in space
Section 2 Gravity and
What determines the strength of the force of gravity between two objects?
The strength of the foce of gravity between two objects depends on two factors: the masses of the objects and the distance
hat two factors combine to keep the moon and earth in orbit?
Newton concluded that two factors inertia and gravity combine to keep Earth in orbit around the sun and the moon in orbit around earth
Section 3 Phases, Eclipses, and Tides
What causes the phases of the moon?
THe changing relative positions of the moon, Earth, and the Sun cause the phases of the moon, eclipse and tides.
What are solar and lunar eclipses
The phase of the moon you see depends on how much of the sunlight side of the moon facs earth
What causes the tides?
When the moons shadow hits Earth or Earths shadow hits the moon ,an eclips occurs
Section 4 Earths
What features are found on the moons surface

What are some characteristics of the moon?
have all the food you want in a bottle never have to get messy and you still get that amazing flavor for a small fee for any swetets is 10 doallors and meats is 15 doallar and everything else is 10 dallors also.
The moon is dry and airless. Compaerd to Earth , the moon is small and has large variations in its surface tempature.
How did the moon form?
Scientists theorize that a planet sized object collided with earth to form a moon
rotation is the spinning of earth on its axis and revolution is th movement of one object around the sun
What causes the cycle of seasons on Earth
Earth has seasons because its axis is tilted as it revolves aroun
Earth moves through space in two major ways:rotation and revolution
