One Complete revolution of Earth around the sun takes about...
one rotation
one season
one year
one eclipse
Earth has seasons because
It rotates on its axis
The distance between Earth and the sun changes
its axis is tilted as it moves around the sun
the temperature of the sun changes
All objects are attracted to each other by the force of
gravity
mass
inertia
weight
The strength of the force of gravity depends on
the masses of the objects and their speeds
the masses of the objects and the distance between them
the weight of the objects and their speeds
the masses of the objects and their weights
The phase of the moon you see depends on
where you are on Earth
How much of the sunlit side of the moon faces Earth
How much of the moons surface is lit by the sun
whether or not an eclipse is occurring
Earths rotation takes about
365 days
6 months
24 hours
1 month
Day and night are caused by
the tilt of Earths axis
Earths revolution around the sun
eclipses
Earths rotation on its axis
An equinox occurs when
neither hemisphere is tilted toward or away from he sun
the Northern Hemisphere is tilted away from the sun
the Northern Hemisphere is tilted toward the sun
Earths axis is parallel to the suns rays
The amount of the lit side of the moon you can see is the same during
new moon and full moon phase
new moon and first quarter phase
first quarter and third quarter phase
full moon and third quarter phase
The different shapes of the moon seen from Earth are called
eclipses
penumbras
umbras
phases
you are less likely to see a total solar eclipse than a total lunar eclipse
the moons shadow covers all of Earth during a solar eclipse
new moon phases occur less often than full moon phases
only people on the daytime side of Earth can see a solar eclipse
the moons umbra only covers a small area on Earths surface
A total eclipse is visible from
all over Earth
only within the moon's umbra
only within the moon's penumbra
only the dark side of Earth
During a total lunar eclipse the moon is in Earth's
corona
penumbra
umbra
orbit
Maria on the moon's surface were formed by ancient
oceans
lava flows
ice flows
meteroid impacts
The temperature of the moon's surface varies greatly from day to night because the moon has
maria
no atmosphere
many craters
highlands
Which parts of the sun's atmosphere become visible during a total solar eclipse?
photosphere and corona
chromosphere and corona
photosphere and chromosphere
prominences and flares
What layer are you looking at when you look at an image of the sun?
photosphere
chromosphere
corona
prominence

In which process do producers use carbon from carbon dioxide to produce other carbon-containing molecules.
the nitrogen cycle
photosynthesis
precipitation
the water cycle
The many overlapping food chains in an ecosystem make up a
food web
niche
energy pyramid
feeding level
Consumers that eat both plants and animals are
omnivores

scavengers
Vultures, which feed on the bodies of dead organisms are
first level consumers
scavengers
producers
herbivores
The first organism in a food chain is always
consumer
herbivore
carnivore
producer
Magnetic field lines around a bar magnet
are only perpendicular
spread out from one end and curve to the other pole
cross back and forth over one another
are perfectly straight
Every magnet, regardless, has 2
magnetic fields
magnetic poles
magnetic charges
magnetic needles
You can increase the strength of an electromagnet' s field by
decreasing the current in the current solenoid
decreasing the number of loops in the solenoid
using a stronger ferromagnetic core
winding the coils more loosely
Magnetic poles that are unlike
attract each other
repel each other
do not interact
point in the same direction
An electric current produces a
magnet
magnetic field
insulator
solenoid
A solenoid with a ferromagnetic core is also called a
elecromagnet
magnetic pole
lodestone
temporary magnet
Magnetic poles that are alike
attract each other
repel each other
do not interact
have the same shape
A device used to measure small currents is called
