Earth, Moon, Space, and Sun
Section 1, Earth in Space
How does Earth move in space?
The Earth rotates around the sun in two ways, rotation and revolution. Rotation is the spinning of the Earth on its axis. When Earth rotates on its axis, the side of earth facing the sun is day and the dark side of Earth is night. Revolution is the movement of one object around another. Earth orbits as it revolves around the sun.
What causes the cycle of the seasons on Earth?
The seasons are caused by the Earth's tilted axis. As Earth revolves around the sun, the axis is tilted which makes the sun more direct in some places and less direct in others. The place where the sun is more direct is experiencing summer. The place where it is less direct is experiencing winter.
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 mass of the objects and the distance between the two.
What two factors combine to keep the moon and Earth in orbit?
Inertia and gravity keep the moon and Earth in orbit. Inertia is the tendency of an object to resist a change in motion.
Section 3, Phases, Eclipses, and Tides
What causes the phases of the moon?
The phases of the moon are caused by the changes of the positions of the Earth, Moon, and Sun. The sun almost always lights up half of the moon, but since the moon revolves around Earth, we see the moon in many different ways.
What are solar and lunar eclipses?
A solar eclipse occurs when the moon passes directly between Earth and the sun, blocking sunlight from Earth.
A lunar eclipse is when Earth blocks sunlight from reaching the moon.
What causes the tides?
Tides are caused by the differences in how much the moon's gravity pulls on different parts of Earth.
Section 4, Earth's Moon
What features are found on the moon's surface?
On the moon's surface there are maria, craters, and highlands.
Maria-The moon's surface has dark, flat areas, which Galileo names Maria.
Craters-Galileo saw that the moon's surface is marked by large round pits, (Craters).
What are some characteristics of the moon?
Some characteristics of the moon are that the moon is dry and airless. Comparing the moon to earth, it is small. The moon is 3,476 kilometers in diameter. The moon also has a variety of temperatures. Temperatures range from 130 degree's C to -180 degree's C.
How did the moon form?
Scientists theory is that the a planet-sized object collided with Earth 4.5 billion years ago. The material of the object and Earth's outer layers was ejected into an orbit around Earth. Gravity caused both materials to combine, and the moon was formed.
