The breaking down and wearing
away of rock by atmospheric forces is called?
deposition
erosion
weathering
subduction A B C D

3. The Answer is weathering C
Natural weathering breaks up rocks into smaller pieces forming sediments.

4. Who Wants To Be A Scientist ?
Next question.
What are large, heavy slabs of ice that move back and
forth across the land depositing weathered rocks and
sediments over time called?
hail
icicles
glaciers
icebergs A B C D

5. The Answer is C glaciers
Glaciers are sheets of ice which move like rivers slowly over the land carving up rocks and sediments as they advance and recede.

6. Who Wants To Be A Scientist ?
Next question,
Which process moves sediments
away from one place to another place?
deposition
erosion
weathering
expansion A B C D

7. The Answer is
erosion B
Erosion takes away the land in one place and builds land in another, moving weathered rock sediments by wind, water, ice or gravity.

8. Who Wants To Be A Scientist ?
Next question please
Which event suddenly releases waves of energy
through the Earth moving huge slabs of crust?
volcanoes
weathering
erosion
earthquakes A B C D

9. The Answer is D earthquakes
Earthquakes shake and shift the crust as slabs of the Earth move against each other under the surface.

10. Who Wants To Be A Scientist ?
The next question is
What kind of rock forms when matter
deposited in layers becomes cemented together?
sedimentary
depository
igneous
metamorphic A B C D

11. The Answer is A sedimentary
Sedimentary rocks form when pieces of rocks, minerals and the remains of living things are cemented together by water into new rock layers.

12. Who Wants To Be A Scientist ?
New question.
Which shows the correct order of events in the
formation of igneous rock?
weathering, erosion
deposit, cementation
melting, magma,
cooling, hardening
squeezing, heating
melting, cooling
hardening, magma A B C D

13. The Answer is B melting, magma, cooling, hardening
Igneous rock is born of fire and volcanic activity and forms when magma or lava cools and becomes solid.

14. Who Wants To Be A Scientist ?
Next question please
Which type of rock is most likely
to contain fossils?
mineral
igneous
sedimentary
metamorphic A B C D

15. The Answer is C sedimentary
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.

16. Who Wants To Be A Scientist ?
Next question
What type of rock forms between a plate
boundary when magma wells up and hardens?
fossil
igneous
sedimentary
metamorphic A B C D

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

when lava rapidly cools in the water after
a volcanic eruption?
granite
slate
obsidian
marble A B C D

19. Obsidian is an igneous rock formed when lava super cools in the water.
The Answer is
obsidian C
Obsidian is an igneous rock formed when lava super cools in the water.

20. Who Wants To Be A Scientist ?
Next question
Which change in the weather would most
likely result in some erosion?
precipitation
temperature
air pressure
humidity A B C D

21. The Answer is A precipitation
Rain is a form of precipitation that moves sediments from one place to another causing errosion.

22. Who Wants To Be A Scientist ? And the next question is
Which tool helps you see
small pieces of matter?
compass
ruler
scale
magnifying
glass A B C D

23. The Answer is magnifying D glass
A magnifying glass has a concave lens that refracts light making objects appear bigger.

24. Who Wants To Be A Scientist ?
Next question please.
This landform consists
primarily of what type
of rock?
fossil
sedimentary
metamorphic
igneous A B C D

25. Volcanic activity forms igneous rock land formations.
The Answer is
igneous D
Volcanic activity forms igneous rock land formations.

26. Who Wants To Be A Scientist ? And the next question is
Which phase of the Moon is visible at night when
the Sun, Earth, and Moon form a straight line?
new moon
crescent
full moon
gibbous A B C D

27. The Answer is C full moon
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.

28. Who Wants To Be A Scientist ?
Next question,
Why does the Moon shine brightly
in the night sky?
It reflects light
from the Sun
from the Earth
It produces its
own light
volcanic eruptions
on the moon A B C D

29. The Answer is It reflects light A from the sun
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.

30. Who Wants To Be A Scientist ? Here is your next question.
The moon causes which of the following
natural events on the Earth?
night and day
seasons
tides
erosion A B C D

31. The Answer is
tides C
The moon’s gravitational pull on the Earth causes the ocean tides on the Earth. Tides can cause erosion.

32. Who Wants To Be A Scientist ?
Next question,
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

33. The Answer is B the seasons
Earth’s tilt causes different seasons to occur in the northern and southern hemispheres.

34. Who Wants To Be A Scientist ?
Next question,
Which property is least useful for
identifying a mineral sample?
luster
hardness
color
streak A B C D

35. The Answer is
color C
Most minerals can occur in a variety of colors, so color is
not a reliable test for identifying a mineral sample.

36. Who Wants To Be A Scientist ?
Next question,
What are Earth and all the other planets in the
solar system constantly doing?
shrinking
glowing
moving
vibrating A B C D

37. The Answer is
moving C
Earth and all the planets rotate and orbit around the sun and are constantly in motion.

38. Who Wants To Be A Scientist ?
New question,
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

39. The Answer is 23 hours, A 56 minutes
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.

40. Who Wants To Be A Scientist ?
Next question,
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

41. The Answer is D it decreases
Less sunlight means less available energy so temperatures decrease in the northern hemisphere in the fall and winter months.

42. Who Wants To Be A Scientist ?
Next question,
During which season are the sun’s rays
the most direct in the northern hemisphere?
summer
fall
winter
spring A B C D

43. The Answer is
summer A
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

44. Who Wants To Be A Scientist ?
Next question,
What is the path of Earth’s revolution around the
Sun called?
rotation
orbit
trek
journey A B C D

45. The Answer is
orbit B
An orbit is the path an object takes around another object in space. Planets orbit stars and moons orbit planets.

46. Who Wants To Be A Scientist ?
Your next question,
How long does it take for Earth to make one orbit
around the Sun?
24 hours
days
29.5 days
9 months A B C D

47. The Answer is
days B
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.

48. Who Wants To Be A Scientist ?
Next question,
Which of the following factors causes the
change of seasons on the Earth?
the tilt of
Earth’s axis
the length of
Earth’s orbit
the distance from
Earth to the Sun
the length of day
and night A B C D

49. The Answer is the tilt of A Earth’s axis
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.
