Solar System
This lunar phase occurs when the Moon is between the Earth and the Sun but is not visible from Earth.
What is the new moon?
This massive gaseous object, composed mainly of hydrogen and helium, is the largest object in our solar system.
What is the sun?
If Earth had no axial tilt but maintained the same orbit, this global pattern would remain constant year-round (2 things).
What is temperature and daylight length?
Galaxies shaped with a central bulge and pinwheel like arms; our solar system is found in one.
What are spiral galaxies?
The distance that light travels in 365 days.
What is one light year?
This type of eclipse can only occur during a full moon.
What is a lunar eclipse?
The layer of the sun where energy from the core travels outward mainly as gamma rays (electromagnetic radiation).
What is The Radiative Zone?
This type of tide is produced when the combined gravitational pull of the sun and moon causes the greatest difference between consecutive high and low tides.
What is a spring tide?
This Law explains how mass and distance affect gravitational force.
What is Newton's Law of Universal Gravitation?
29.5 days is the amount of time it takes for this particular revolution.
What is the moon revolving around Earth?
This is the area of the eclipse is the darkest part of the shadow because the suns light is fully blocked.
What is the umbra?
Very hot fluid like gas consisting of electrically charged particles.
What is plasma?
When the sun and moon form a right angle with Earth, this specific tidal pattern results.
What are neap tides?
A comet speeds up as it approaches the sun because of this change in gravitational interaction.
What is increased gravitational force due to decreased distance?
What is Saturn?
Astronomers use this unit to describe the average distance between the centers of the Earth and the sun.
What is one astronomical unit (AU)?
The suns outer atmospheric layer that can extend millions of kilometers into space and is visible as a glowing halo.
What is the corona?
If Earth's axis were tilted at 0 degrees, this observable pattern would no longer occur.
What are seasons?
A planet with greater inertia requires this change to alter its orbit significantly.
What is a larger gravitational force?
What are solar prominences?
Name the four terrestrial planets made primarily of rock and metal, in order from the sun outward.
What are Mercury, Venus, Earth, and Mars?
Areas of plasma that are cooler than the plasma around them resulting in a darker appearance. They can be seen on the largest object in the solar system.
What are sunspots?
This reasoning best explains why coastal locations experience two high tides approximately every 24 hours.
What is Earth's rotation combined with the gravitational pull creating tidal bulges?
Galileo's telescopic observations provided this evidence that directly contradicted the geocentric model and supported a sun centered system governed by gravitational interactions.
What are the phases of Venus?
Saturns largest moon, known for its icy surface and methane- ethane rivers, and larger than Earth's moon.
What is Titan?
