Earth in Space
1.How does Earth move in space?
Earth travels around the moon, this is called revolution. Earth also spins around its axis.
2. What causes the cycle of seasons on Earth?
Earths axis causes the cycle of seasons. The Earths axis is tilted as it revolves around the sun causing the temperatures to be spread differently.
Gravity and Motion
1. What determines the strength of the force of gravity between two objects.
The mass and distance determines the strength of the force.
2. What two factors combine to keep the moon and earth in orbit.
Inertia and gravity keep the Earth and Moon in orbit. Earths gravity pulls the moon towards it so the moon cant travel in a straight line.
Phases, Eclipses and tides
1. What causes the phases of the moon?
The changing relative positions of the moon, Earth, and sun because the phases of the moon, eclipses , and tides.
2. What are Lunar and Solar Eclipses?
When the moons's shadow hits Earth or Earth's Shadow hits the moon, and eclipses occurs.
3. What causes the tides?
Tides are mostly caused by differences in how much the moon's gravity pulls on different parts of the earth.
1.What features are found on the moon's surface.
Some features are maria, craters, and highlands.
2. What are some characteristics of the moon?
The moon is dry, and airless. Compared to the earth , the moon is small and has large variations in its temperature.
3. How did the moon form?
Scientists theorize that a planet size object collided with Earth to form the moon.
