True or False: The moon has layers?
True
Which is the closest star to Earth?
the Sun
Name 2 of the 4 terrestial planets
mercury, venus, earth, or mars
Name 2 radiation types used in telescopes - not visible light
Any two: gamma, x-ray, ultraviolet ( UV ), infrared ( IR ), radio, or microwaves
Name the shape and name of our galaxy.
spiral and Milky Way
Name any two landforms found on the moon.
crater, rilles, mountains, mare, or rays
List 3 ways we can categorize stars.
size, luminosity, temperature, or color
Explain the motion of the Red Spot on Jupiter
It is a tremendous storm that has been ongoing for hundreds of years.
What does a lens do to light waves?
Bend them ( refract)
Why does a comet's tail point away from the Sun and get bigger the closer it comes to the Sun?
Solar winds push dust from the tail away.
The heat of the Sun makes more gases form and more ionization occur.
Why are there so many more craters on the moon, than on Earth?
With no weather, weathering and erosion do not erase the craters.
Explain nuclear fusion.
when the temperature rises in a star's core, the elements or atoms start to fuse with each other
generating tremendous amounts of energy.
Explain why an atmosphere can be a good thing for a planet.
Shields us from incoming debris - meteors, asteroids, etc. It also blocks harmful radiation from the Sun.
Why are space telescope images clearer than ones taken on telescopes on earth?
no light pollution, no interference with atmosphere, closer to some objects
What do galaxies contain? Name at least 3 objects.
Stars, gases, dust, moons, planets, asteroids, meteors
Explain the order of the Sun, Earth, and Moon during a lunar eclipse or a solar eclipse.
Lunar eclipse - sun, earth, and moon
Solar eclipse - earth, moon, and sun
What is the name of the chart that shows the categories of stars?
The H-R Diagram
Explain the Greenhouse Effect on Venus. What gas is creating it.
Infrared radiation enters the atmosphere of venus, but when it is re-radiated from the surface; it gets trapped in a super thick carbon dioxide atmosphere, creating a very hot planet.
If you have a high energy wave, it has _________ frequency and ___________ wavelength.
high frequency, and long wavelengths
What is a force that creates motion between stars?
Gravity
Explain why the phases of the moon occur.
As the moon revolves around the Earth, it is illuminated by the Sun in different areas. For
a new moon, most of the Sun's light is blocked by the Earth.
What are the two possible end points of a super massive star?
Neutron star or black hole
In a circle, what is the distance from one side to the other called?
diameter
Why are reflecting telescopes larger than refracting telescopes?
Reflecting telescopes use mirrors that are easier to make larger and lighter than lenses.
True or False: We are able to estimate the mass of the Sun by calculating motion in the planets orbiting the Sun.
True
because the gravitational pull depends on the planet's mass and velocity.
