Earth, Moon, and Sun

Section 1 Earth In Space

How does earth move in space?

Earth Rotates on its axis. Its axis is an imaginary line that passes through Earths center. The Earth revolves around the sun while it rotates on its axis. Earth follows a path or an orbit as it revolves around the sun.

Rotation is the spinning of earth on its axis.

Revolution is the movement of one object around another.

What causes the cycle of seasons on Earth?

Most places outside the tropics have four distinct seasons, winter, spring, summer, and fall. Sunlight hits earth more directly at the equator. This is why it is warmer at the equator than the poles.

Earth has seasons because its axis is tilted as it revolves around the sun. The Earths axis is tilted away from the sun for part of the year and towards the sun for part of the year.

An imaginary line that passes through Earths center and the north and south poles is Earths axis.

Section 2 Gravity and Motion

What determines the force of gravity between two objects?

The strength of the force of gravity between two objects depends on two factors: the masses of the objects and the distance between them. The strength of gravity is affected by the distance between two objects as well as their masses.

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

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

Inertia is the tendency of an object to resist a change in motion.

Gravity attracts all objects towards it.

Section 3 Phases, Eclipses, and Tide

What Causes the Phases of the Moon?

The different shapes of the moon you see from Earth are called phases. The phases of the moon you see depends on how much of the sunlit side of the moon faces Earth.                                                        

What are solar and Lunar Eclipses?

Eclipse is when the moons shadow hits Earth or Earth's shadow hits the moon, an eclipse occurs.

A lunar eclipse occurs at a full moon when Earth is directly between the moon and the sun.

What Causes tides?

Tides are mainly caused  by differences in how much the moon's gravity pulls on different parts of Earth.

Section 4 Earths Moon

What features are found on the Earth's surface?

Some features that are fond on the Earth's surface are maria, craters, and highlands.

Maria is dark flat surfaces, it is the Latin word for "seas". Craters are large round pits.Craters are caused by meteoroids, chunks of rock or dust from space.

What are some of the 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?

The theory of the moons origin that seems to fit the evidence is called the collision-ring theory. Scientists theorize that a planet-sized object collided with Earth to form the moon. Material from the object and Earth's outer layers were ejected into orbit around Earth, where it formed a ring.
