sediments over time called?
hail
icicles
glaciers
icebergs
A
B
C
D
The Answer is
glaciersC
Glaciers are sheets of ice which move like rivers slowly over the land carving up rocks and sediments as they
advance and recede.

weathering
expansion
A
B
C
D
Next question,
Who Wants To Be A Scientist ?

deposit, cementationsqueezing, heating
melting, coolinghardening, magma
A
B
C
D
The Answer is
melting, magma,cooling, hardening B
Igneous rock is born of fire and volcanic activity and forms when magma or lava cools and becomes solid.

Which type of rock is most likely to contain fossils?
mineral
igneous
sedimentary
metamorphic
A
B
C
D
The Answer is
sedimentaryC
Fossils are the remains or traces of organisms that lived in the past. Over time organisms die and are covered with
sediments which are eventually cemented together forming layers of sedimentary rock.

What type of rock forms between a plateboundary when magma wells up and hardens?
fossil
igneous
sedimentary
metamorphic
A
B
C

Plate boundaries are places where lava escapes from the mantle of the Earth. As lava cools it forms new
igneous rocks.

a volcanic eruption?
granite
slate
obsidian
marble
A
B
C
D
Next question,

Obsidian is an igneous rock formed when lava super cools in the water.
Which change in the weather would mostlikely result in some erosion?
precipitation
temperature
air pressure
humidity
A
B
C
D
Next question
Who Wants To Be A Scientist ?
The Answer is
precipitationA
Rain is a form of precipitation that moves sediments from one place to another causing errosion.

C
D
Who Wants To Be A Scientist ?And the next question is
The Answer is
magnifyingglass
D
A magnifying glass has a concave lens that refracts light making objects appear bigger.

This landform consists primarily of what type of rock?
fossil
sedimentary
metamorphic
igneous
A
B
C
D
Next question please.
The Answer is
igneousD
Volcanic activity forms igneous rock land formations.
Which phase of the Moon is visible at night whenthe Sun, Earth, and Moon form a straight line?
new moon
crescent
full moon
gibbous
A
B
C
D
Who Wants To Be A Scientist ?And the next question is
The Answer is
full moonC
Both the new and full moons phases occur when the Sun, Earth and Moon form a straight line, but only the full
moon phase is visible in the night sky.
Why does the Moon shine brightlyin the night sky?
It reflects light from the Sun
It reflects light from the Earth
It produces its own light
volcanic eruptions on the moon
A
B
C
D
Who Wants To Be A Scientist ?Next question,
The Answer is
It reflects lightfrom the sun
A
The moon doesn’t make any light of its own. The light we see is sunlight that hits the moon and is reflected to
Earth.
The moon causes which of the followingnatural events on the Earth?
night and day
seasons
tides
erosion
A
B
C
D
Who Wants To Be A Scientist ?Here is your next question.
The Answer is
tidesC
The moon’s gravitational pull on the Earth causes the ocean tides on the Earth. Tides can cause erosion.
Which is an effect of the 23.5 degree tilt of our Earth on its axis?
day and night
the seasons
gravity
ocean tides
A
B
C
D
Who Wants To Be A Scientist ?Next question,
The Answer is
the seasonsB
Earth’s tilt causes different seasons to occur in the northern and southern hemispheres.
Which property is least useful foridentifying a mineral sample?
luster
hardness
color
streak
A
B
C
D
Who Wants To Be A Scientist ?Next question,
The Answer is
colorC
Most minerals can occur in a variety of colors, so color is not a reliable test for identifying a mineral sample.
What are Earth and all the other planets in the solar system constantly doing?
shrinking

A
B
C
D
Who Wants To Be A Scientist ?Next question,
The Answer is
movingC
Earth and all the planets rotate and orbit around the sun and are constantly in motion.
The spinning motion of Earth is called rotation.Exactly how long does it take the Earth to complete
one rotation on it axis?
23 hours, 56 minutes
356 days, 16 hours, 6 minutes
29.5 days
24 hours, 37 minutes
A
B
C
D
Who Wants To Be A Scientist ?New question,
The Answer is
23 hours,56 minutes
A
Earth actually makes one rotation on its axis in just under one day. We round up to 24 hours for practical
time keeping on Earth. Mars takes just over 24 hours to make one rotation, or day, on Mars.
As longer summer days become shorter in the fall and winter months in North America,
what happens to the available solar energy?
it increases
it’s the same
nothing
it decreases
A
B
C
D
Who Wants To Be A Scientist ?Next question,
The Answer is
it decreasesD
Less sunlight means less available energy so temperatures decrease in the northern hemisphere in the fall and
winter months.
During which season are the sun’s raysthe most direct in the northern hemisphere?
summer
fall
winter
spring
A
B
C
D
Who Wants To Be A Scientist ?Next question,
The Answer is
summerA
Although Earth is furthest away from the sun in its orbit in the summer, the northern hemisphere gets the most
direct sunlight and available solar energy in the summer season because Earth is tilted on its axis
What is the path of Earth’s revolution around theSun called?
rotation
orbit
trek
journey
A
B
C
D
Who Wants To Be A Scientist ?Next question,
The Answer is
orbitB
An orbit is the path an object takes around another object in space. Planets orbit stars and moons orbit planets.
How long does it take for Earth to make one orbit around the Sun?

365.25 days
29.5 days
9 months
A
B
C
D
Who Wants To Be A Scientist ?Your next question,
The Answer is
365.25 daysB
One Earth orbit, or year, takes exactly 365 days, 6 hours, and 16 minutes. We round down to 365 days for practical
time keeping and add one day, “leap day in leap year”, every 4 years to adjust our calendars.
Which of the following factors causes thechange of seasons on the Earth?
the tilt of Earth’s axis
the length of Earth’s orbit
the distance fromEarth to the Sun
the length of dayand night
A
B
C
D
Who Wants To Be A Scientist ?Next question,
The Answer is
the tilt of Earth’s axis
A
The Earth’s tilted axis causes the change of seasons in the northern and southern hemispheres. Both the length of day and night and change in temperatures are effects
of the tilt.
