Which statement describes velocity?
30 m/s
30 m East
30 m/s East
30 m
What is the difference between speed and velocity?
Velocity is the change over time; while speed is the change in velocity over time.
Velocity has a specific direction associated with it while speed has no specific direction
Velocity has no direction associated with it while speed has a specific direction attached to it.
The forces acting on an object that do not change an object's motion or cause no motion are called:
unbalanced forces
balanced forces
net forces
terminal forces
An object at rest or in motion will remain that way until acted upon by an unbalanced force. This is Newton’s -
First Law
Second Law
Third Law
Gravity Law
Which situation best explains the law of force and acceleration (Newton’s Second Law)? (Force = Mass X Acceleration)
restraints keep passengers from falling out of a roller coaster when it travels upside down
a larger force will be required to accelerate a roller coaster car with more people
Riders must be certain heights so they have enough mass to ride the roller coaster
Which is NOT a component of galaxies?
Universe
Stars
Nebulae
Planets
Which shape does NOT describe a type of galaxy?
Spiral
Elliptical
Circular
Irregular
The Sun is classified as a main sequence star. This indicates the Sun is -
at the center of our galaxy
a medium - sized star
a star fueled by hydrogen
a massive star
Scientists use light years as a measurement of distance in space. A light year is a specific distance in space. It is the distance light travels in -
from the Sun to the edge of our Solar System
in one year
from the Sun to the edge of our galaxy
from the Sun to Earth
Which would represent Newton’s Law of Action-Reaction?
toy car rolling down a ramp
toy rocket being launched
toy boat floating in the water
toy tractor being pushed over a hill
Which of these best compares the conditions at Location X and Location Y?
It is day at Location X and night at Location Y
It is winter at Location X and summer at Location Y
There are more hours of daylight at Location X than at Location Y.
The moon is brighter when viewed from Location X than when viewed from Location Y
Earth would not have seasons if it —
no longer tilted on its axis
stopped rotating on its axis
took an additional month to orbit the sun
revolved around the sun in the opposite direction
When the Northern Hemisphere is tilted away from the Sun -
it is night in the Northern Hemisphere.
the Sun's rays do not strike the Northern Hemisphere.
the South Pole is pointing directly at the Sun.
it is summer in the Southern Hemisphere.
If the moon is ‘growing’ or appearing to get bigger, it is called -
Waxing
Waning
A student keeps a record of the phases of the moon for one month. On the first night of the student’s observations, the full moon is visible in the sky. After the full moon, (getting smaller) which of these phases will the student observe next?
Waxing crescent moon
Waxing gibbous moon
Waning crescent moon
Waning gibbous moon
Most of Earth's volcanoes are formed by —
meteorites that strike continental plates.
water evaporating on continental plates.
the meeting or separation of continental plates.
the melting of ice on continental plates.
The diagram shows Earth, the Moon, and the Sun during spring tides.
At new moons and full moons, Earth, the Moon, and the Sun are aligned. This means that when there are new moons and full moons, high tides on Earth are —
everywhere simultaneously.
unusually high.
unusually low.
at their average height.
According to the theory of plate tectonics, where do activities such as earthquakes and volcanic eruptions occur?
Above the surfaces of plates
In the outer regions of plates
Along plate boundaries
In the centers of plates
What is the difference in elevation in meters between Point X and Point Y on the map?
380
360
460
440
The erosion features represented by branching lines are —
river valleys
glaciers
inland seas
oceans
