3The Answer is weathering C Natural weathering breaks up rocks into smaller pieces forming sediments.
4Who Wants To Be A Scientist ? Next question.What are large, heavy slabs of ice that move back andforth across the land depositing weathered rocks andsediments over time called?hailiciclesglaciersicebergsABCD
5The 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.
6Who Wants To Be A Scientist ? Next question,Which process moves sedimentsaway from one place to another place?depositionerosionweatheringexpansionABCD
7The Answer iserosionBErosion takes away the land in one place and builds land in another, moving weathered rock sediments by wind, water, ice or gravity.
8Who Wants To Be A Scientist ? Next question pleaseWhich event suddenly releases waves of energythrough the Earth moving huge slabs of crust?volcanoesweatheringerosionearthquakesABCD
9The Answer is D earthquakes Earthquakes shake and shift the crust as slabs of the Earth move against each other under the surface.
10Who Wants To Be A Scientist ? The next question isWhat kind of rock forms when matterdeposited in layers becomes cemented together?sedimentarydepositoryigneousmetamorphicABCD
11The 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.
12Who Wants To Be A Scientist ? New question.Which shows the correct order of events in theformation of igneous rock?weathering, erosiondeposit, cementationmelting, magma,cooling, hardeningsqueezing, heatingmelting, coolinghardening, magmaABCD
13The 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.
14Who Wants To Be A Scientist ? Next question pleaseWhich type of rock is most likelyto contain fossils?mineraligneoussedimentarymetamorphicABCD
15The 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.
16Who Wants To Be A Scientist ? Next questionWhat type of rock forms between a plateboundary when magma wells up and hardens?fossiligneoussedimentarymetamorphicABCD
17The Answer isigneousBPlate boundaries are places where lava escapes from the mantle of the Earth. As lava cools it forms newigneous rocks.
18Who Wants To Be A Scientist ? Next question,Which black, glassy rock formswhen lava rapidly cools in the water aftera volcanic eruption?graniteslateobsidianmarbleABCD
19Obsidian is an igneous rock formed when lava super cools in the water. The Answer isobsidianCObsidian is an igneous rock formed when lava super cools in the water.
20Who Wants To Be A Scientist ? Next questionWhich change in the weather would mostlikely result in some erosion?precipitationtemperatureair pressurehumidityABCD
21The Answer is A precipitation Rain is a form of precipitation that moves sediments from one place to another causing errosion.
22Who Wants To Be A Scientist ? And the next question is Which tool helps you seesmall pieces of matter?compassrulerscalemagnifyingglassABCD
23The Answer is magnifying D glass A magnifying glass has a concave lens that refracts light making objects appear bigger.
24Who Wants To Be A Scientist ? Next question please.This landform consistsprimarily of what typeof rock?fossilsedimentarymetamorphicigneousABCD
25Volcanic activity forms igneous rock land formations. The Answer isigneousDVolcanic activity forms igneous rock land formations.
26Who Wants To Be A Scientist ? And the next question is Which phase of the Moon is visible at night whenthe Sun, Earth, and Moon form a straight line?new mooncrescentfull moongibbousABCD
27The 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.
28Who Wants To Be A Scientist ? Next question,Why does the Moon shine brightlyin the night sky?It reflects lightfrom the Sunfrom the EarthIt produces itsown lightvolcanic eruptionson the moonABCD
29The 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.
30Who Wants To Be A Scientist ? Here is your next question. The moon causes which of the followingnatural events on the Earth?night and dayseasonstideserosionABCD
31The Answer istidesCThe moon’s gravitational pull on the Earth causes the ocean tides on the Earth. Tides can cause erosion.
32Who Wants To Be A Scientist ? Next question,Which is an effect of the 23.5 degree tiltof our Earth on its axis?day and nightthe seasonsgravityocean tidesABCD
33The Answer is B the seasons Earth’s tilt causes different seasons to occur in the northern and southern hemispheres.
34Who Wants To Be A Scientist ? Next question,Which property is least useful foridentifying a mineral sample?lusterhardnesscolorstreakABCD
35The Answer iscolorCMost minerals can occur in a variety of colors, so color isnot a reliable test for identifying a mineral sample.
36Who Wants To Be A Scientist ? Next question,What are Earth and all the other planets in thesolar system constantly doing?shrinkingglowingmovingvibratingABCD
37The Answer ismovingCEarth and all the planets rotate and orbit around the sun and are constantly in motion.
38Who Wants To Be A Scientist ? New question,The spinning motion of Earth is called rotation.Exactly how long does it take the Earth to completeone rotation on it axis?23 hours, 56 minutes356 days, 16 hours,6 minutes29.5 days24 hours, 37 minutesABCD
39The 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.
40Who Wants To Be A Scientist ? Next question,As longer summer days become shorterin the fall and winter months in North America,what happens to the available solar energy?it increasesit’s the samenothingit decreasesABCD
41The Answer is D it decreases Less sunlight means less available energy so temperatures decrease in the northern hemisphere in the fall and winter months.
42Who Wants To Be A Scientist ? Next question,During which season are the sun’s raysthe most direct in the northern hemisphere?summerfallwinterspringABCD
43The Answer issummerAAlthough 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
44Who Wants To Be A Scientist ? Next question,What is the path of Earth’s revolution around theSun called?rotationorbittrekjourneyABCD
45The Answer isorbitBAn orbit is the path an object takes around another object in space. Planets orbit stars and moons orbit planets.
46Who Wants To Be A Scientist ? Your next question,How long does it take for Earth to make one orbitaround the Sun?24 hoursdays29.5 days9 monthsABCD
47The Answer isdaysBOne 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.
48Who Wants To Be A Scientist ? Next question,Which of the following factors causes thechange of seasons on the Earth?the tilt ofEarth’s axisthe length ofEarth’s orbitthe distance fromEarth to the Sunthe length of dayand nightABCD
49The 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.
