    To which type of sand stone belong?

    Sedimentary

  • 8

    Which is a biotic component of the ecosystem?

    Organism

  • 9

    What type of thermonuclear reaction that occurs in the sun which generates a tremendous amount of energy?

    Fusion

  • 10

    How can you help minimize the heavy pollution that is caused by excessive carbon dioxide emissions in the surroundings?

    Burry garbage rather than burn it

  • 11

    What phenomenon occurs when the length of day and night varies depending on the inclination of the earth’s axis? a. c. b. d.

    Solstice

  • 12

    Why do four seasons occur on Earth?

    The earth’s axis is tilted.

  • 13

    A teacher demonstrated the possible effects of acid rain by placing several types of rocks in separate beakers containing a vinegar solution with a pH of 3. As time passed, some of the solutions retained a pH of 3 while other solutions gradually reached a pH of 7. Which of the following best explains this variation of pH in this demonstration?

    The rocks have varying chemical composition, so some but not all of them react with acid.

  • 14

    A day on Saturn takes about 10 Earth hours. Which fact would best explain this short day?

    Saturn rotates more rapidly than Earth.

  • 15

    In an area where a river has cut deep into Earth, there are several layers of very different rock exposed. The oldest rock layer is most likely to be the layer that is

    below the other layers.

  • 16

    Which of the following statements best describes how the planets of the solar system formed?

    They formed from a nebular cloud of dust and gas

  • 17

    The existence of extraterrestrial life may never be proven, but this idea will become more scientifically acceptable over time if

    increasing scientific evidence supports the idea.

  • 18

    Which of the following is the best evidence that Earth’s continents were once in vastly different positions than they are today?

    Fossils of tropical plants are found in Antarctica

  • 19

    Evidence suggests that Earth is about 4.6 billion years old, even though no Earth rocks have been found that can be dated at more than 4 billion years old. This discrepancy is most likely caused by Earth’s original crust being

    subject to extensive erosion.

  • 20

    As part of the modern theory of the origins of the elements, it is hypothesized that before the formation of the stars, most of the matter in the universe consisted of what atoms?

    hydrogen and helium

  • 21

    Stars begin their life cycle in ___

    A rift valley is evidence of which kind of plate boundary?

    divergent

  • 24

    The convergence of two continental plates would produce

    folded mountains

  • 25

    It is generally true that igneous rocks

    are composed of silicate minerals.

  • 26

    Which type of volcano would be the least explosive?l

    shield volcano

  • 27

    The Richter scale measures which of the following earthquake characteristics?

    magnitude

  • 28

    Only about 50% of the solar energy directed toward Earth penetrates directly to the surface. What happens to the rest of the radiation?

    It is absorbed or reflected by the atmosphere.

  • 29

    The Moon is very hot on the side facing the Sun and very cold on the dark side. This extreme temperature difference is primarily due to the Moon’s

    thin atmosphere.

  • 30

    Venus is warmed by solar radiation, but its thick cloud cover increases the temperature because the clouds ____

    prevent the escape of heat into space.

  • 31

    Which of these could increase average global temperatures?

    fuels increased use of fossil

  • 32

    More solar energy reaches the equatorial regions than the polar regions because the equatorial regions _____

    receive sun rays closest to vertical.
