Particles moving towards Earth's magnetic poles circulate around magnetic field lines and become energized. When they return to their original energy levels, they emit light. What is this light called?
Spectral light
Auroras
Rainbow
Nebula
In history, how was a month defined?
From sunrise to sunset
From new moon to new moon
The Sun completing a zodiac cycle
28 days
The critical part of the atmosphere that protects life on the ground from excessive ultraviolet radiation is:
Troposphere
Ozone layer
Stratosphere
Ionosphere
The region around Earth where the magnetic field traps charged particles is:
Ozone layer
Exosphere
Van Allen radiation belts
Corona
How many tides occur each day?
1 high, 1 low
2 high, 2 low
2 high, 1 low
1 high, 2 low
What is the name for the effect shown in the diagram to the right?
Coriolis Effect
Van Allen Effect
Aurora Effect
Earth's Motion Effect
Why do oceans contain higher levels of carbon dioxide than the atmosphere?
There are many organisms in the sea producing carbon dioxide.
The salt reacts with the water to produce carbon dioxide.
The sea floor sediments contain all of the carbon dioxide.
Carbon dioxide dissolves in rainwater and accumulates in the oceans.
What technique is used to determine the age of Earth's rocks and fossils?
Radium dating
Radioactive dating
Earth rock dating
Isotope dating
What happens when two tectonic plates collide?
They both stop moving
Volcanoes always mark the boundary between them
That region is safe from earthquakes
They continue moving, creating a variety of formations
Which of the following is NOT caused by the rotation of the Earth?
Wind currents
Seasons
Magnetic field
Ocean currents
At which lunar phase would the tidal variation be the greatest?
New moon
Waxing crescent
Waning gibbous
Third quarter moon
What caused the Earth to be a sphere?
Its rotation
Gravity
Its revolution
The Moon
From the center outward, the correct order of Earth's layers is:
Liquid iron inner core, solid nickel outer core, rocky mantle, silicate crust
Solid metallic inner core, molten metal outer core, silicate mantle and crust
Solid rock core, liquid metal mantle, solid rock crust
Molten metal inner core, molten rock mantle, solid silicate crust
Which of the following statements is NOT true regarding the greenhouse effect?
The increased emission of greenhouse gases is a natural process.
Life on Earth is possible due to the greenhouse effect.
Increased emissions of greenhouse gases in the atmosphere increase Earth's temperature.
The greenhouse effect is a natural process that maintains Earth's temperature.
How are magnetic fields generated?
By solid metallic materials
By spinning molten rock
By the motion of electric currents
By the Dynamo effect
How old do scientists believe the Earth to be?
4.5 million years
3.5 billion years
4.5 billion years
3.5 trillion years
Why is the orbit of our Moon considered an oddity?
It is a perfect circle, instead of an ellipse.
It is much further away than most orbits.
It lies at an angle instead of in its planet's equatorial plane.
Its rotation in orbit is synchronized with its revolution around the Earth.
Which section of the atmosphere contains the ozone layer?
Troposphere
Stratosphere
Mesosphere
Thermosphere
Which major atmospheric component is primarily a product of life processes?
Carbon dioxide
Water
Oxygen
Nitrogen
Daylight Saving Time originally started in an effort to conserve energy during which war?
World War I
World War II
Vietnam War
Korean War
Earth's magnetic field partially shields us from charged particles emitted by the Sun and energy particles produced by violent cosmic events in space. What are these particles called?
cosmic rays
charged ions
isotopic radiation
space pollution
Which theory of the Moon's origin is now most favored?
Like the moons of Jupiter, our moon condensed from leftovers around the equator of the newly formed Earth.
The rapidly spinning Earth slung the Moon off from what is now the Pacific Ocean Basin.
The Moon was a large comet, from the Oort Cloud, which has now lost almost all of its ices.
A Mars-sized body struck the young Earth, tilting us over 23.5 degrees and blowing out ejecta that condensed into the Moon.
In which part of our atmosphere do we live?
troposphere
stratosphere
mesosphere
thermosphere
What is the name for the areas around Earth shown above?
tidal bulge
magnetic field
Van Allen radiation belts
auroras
The best way to find the exact distance to the Moon is to:
Measure its exact size in the telescope.
Use radar reflection times, about 2.56 seconds.
Bounce lasers off the retro reflectors left on the surface by the Apollo landings.
Make parallax measurements from observatories on opposite sides of the Earth.
Which of the following is NOT true regarding the Moon's atmosphere?
The Moon's interior is too cold to have an atmosphere.
The Moon lacks the gravity necessary to hold captured gases for an atmosphere.
The Moon contains a small amount of gases near its poles and around its body.
The Moon has an atmosphere with large amounts of hydrogen and helium.
Where does the Earth's magnetic field originate from?
Crust
Mantle
Liquid Outer Core
Solid Inner Core
Why is heat trapping by gases in the atmosphere called the greenhouse effect?
Because like a greenhouse, the atmosphere is permeable to both heat and sunlight.
Because like a greenhouse, the atmosphere is impermeable to sunlight.
Because like a greenhouse, the atmosphere is permeable to sunlight and impermeable to heat.
Because like a greenhouse, the atmosphere is impermeable to both sunlight and heat.
At which phase would the tidal variation be the least during the entire day?
New moon
First quarter
Waxing gibbous
Waning crescent
What is the primary gas in our atmosphere?
Oxygen
Carbon Dioxide
Nitrogen
Hydrogen
How do scientists study the inside of the Earth?
Sending probes down volcanoes
Drilling holes down into the mantle
Using SONAR to see reflected objects
Using waves from earthquakes
