1.1 Sky from Earth/ 1.2 Earth in Space
What does rotation cause?
Change of day and night
This force pulls objects toward each other
Gravity
This is the term for the different shapes of the Moon seen from Earth.
Phases
What are tides?
The rise and fall of ocean water.
Which scientist was the first to use a telescope to observe the Moon?
Galileo Galilei
What shape is Earth's orbit?
elliptical
This scientist developed the Universal Law of Gravitation.
Isaac Newton
What is an eclipse?
When one object in space blocks another and casts a shadow.
How many high tides occur each day?
2
What are maria?
The large, dark, flat areas formed by lava.
What are constellations used for?
Storytelling, farming, navigation
What is mass?
This is the amount of matter in an object.
What is a solar eclipse?
This type of eclipse occurs when the Moon is between Earth and the Sun.
What are spring tides?
The tides that have the greatest difference between high and low tide
What are craters?
Large round pits caused by meteoroid impacts.
What is the difference between meteors and comets?
Meteors: Streaks of light appear when space rocks burn in Earth’s atmosphere.
Comets: Cold objects that develop a glowing tail when they get close to the Sun.
This changes depending on location due to gravity.
Weight
What is an umbra?
The darkest part of a shadow during an eclipse.
What moon phases do neap tides occur in?
Neap tides occur during first and third quarter moons.
What are highlands?
The mountainous regions that cover most of the Moon’s surface
What two factors cause the seasons on Earth?
Earth’s tilt and revolution
What is Newton's First Law?
This law states that an object in motion stays in motion unless acted on by a force.
Put the Moon phases in order starting from New Moon.
New Moon → Waxing Crescent → First Quarter → Waxing Gibbous → Full Moon → Waning Gibbous → Third Quarter → Waning Crescent?
What causes tides on Earth?
The gravitational pull of the Moon and the Sun
What is collision theory?
An explanation that the Moon formed after a large object hit Earth.
