6 A. Top Soil Most Fertile soil Humus Top Soil Humus

7 D. Deep within the Earth Metamorphic rocks most likely forms Heat and Pressure Heat and pressure is usually deep in the Earth

8 C. The mountain was once below water Seashell fossil discovered on top of a mountain, what is a good scientific reason? Mountain Seashells (sea animals) normally live in oceans. Mountain are formed on land in the oceans

10 D. Z At which point are the oldest rocks? New Old

11 D. One year (365 ¼ days) One revolution of Earth around the SUN equal to Spring Summer Sun Fall Winter 1 year

12 C. The length of the day would increase If Earth’s rotation (spin) slowed I would take more time to make one spin Day and Night would take longer. We would see longer days and longer nights.

13 A. A Which layer contains the humus? Humus Top Soil, layer A

14 C. Outer Core Which layer is made up of liquid Iron and Nickel? Solid Iron Liquid Iron Molten Rock Solid Rock

15 C. Inner core, outer core, mantle, crust Highest to the lowest pressures Highest Pressure Lowest Pressure

16 B. Drought What could happen during long period of low precipitation? Precipitation = rain, snow, sleet, hail… mostly RAIN Low Precipitation = Very little rain = Dry Drought = little or no rain

17 A. Y, W, X, Z Soil horizons: the correct sequence 2 Decaying organic matter Silt and Clay Rock fragments Bedrock 3 1 4

18 B. Water Renewable resource Things that can be used over and over. Things that will not run out Trees Water Sun Wind.

19 C. Continental Slope What is letter “Y” ? Continental SHELF Continental RISE Continental SLOPE

20 D. Continental drift theory What theory do the maps support? PANGEA ( Supercontinent ) The continents are moving apart (at the mid-ocean ridges)

21 D. Winter If It is SUMMER in the NORTH, then south is … Summer Winter

22 C. Choice “C” How much of the Earth’s SURFACE is COVERED with water Equal A C B D About 2/3 Too much land Too much water

23 C. Jupiter Earth 1 moon Mars 2 moons Jupiter Pluto 30 -70 moons 3 moons Which Planet is it Gas Giants ( Jupiter, Saturn, Uranus, & Neptune) All have A LOT of moons.

24 D. Coal Which is NON-renewable ? Things that cannot be replaced. Once used, it is gone. Wind /Air Water Soil Coal Renewable CANNOT Things that are burned are NOT renewable

25 D. The moon Object that is responsible for the tides on Earth L H H H L L L H

26 C. A day would be longer Time it took the Earth to rotate increased Time increased = It took longer to rotate It took more time to spin It did not say it took longer to go around the Sun

27 D. 40 km/h What would produce the highest waves Strongest winds

28 B. Gravity What is the force at “X” ? Gravity Without this force, The planet would fly away Gravity holds the universe together

29 B. Which illustration is rotation Rotation = Spin Rotation Revolution

30 What is the moon phase for the following alignment A B C D

31 D. The Earth Which object is the smallest. Universe is the BIGGEST SUN Earth Galaxy There are BILLIONS of galaxies in the Universe

32 B. Continental plate is colliding with another continental plate What is occurring in the illustration ? Building mountains Collision Continent The picture does not show any ocean information

33 D. The moon would fly away from earth What would happen to the moon if gravity is no more gravity? Without gravity, The moon would fly away

34 C. 70 % What Percent of the Earth is covered by water? About 70%

35 C. Precipitation What is occurring at point Y? Condensation Evaporation Precipitation

36 D. Part solid and part liquid Earth Core is made of: There are 2 cores ( Inner core and Outer core ) Solid Iron Liquid Iron Molten Rock Solid Rock

37 B. Mantel Layer marked “X” Inner core Outer core Mantel Crust

38 A. Which is a crescent moon? A B C D Crescent looks like a “C” White part is what you see, not the black.

39 C. More dense than the air rising over the land Air over the sea during daytime… Warm, less dense Cool, more dense
