Multiple Choice Game
Welcome to the Multiple Choice Game section! Here you can test your knowledge on the earth's
surface and related information. Click on "Answers" at the end of the game to find how
well you did. Enjoy!
A. What happens when two continental plates collide?
- 1) The plate moving with lesser force subducts under the one moving with greater force.
- 2) The two plates will both subduct under each other.
- 3) One of the plates will be forced under the other slightly, but no subduction takes place.
B. What happens when volcanoes erupt?
- 1) Pyroclastic and mud flows, tsunamis, release of poisonous gases, smoke, lava and ash.
- 2) Prolonged thunder and lightning, and destructive thunderstorms.
- 3) More plate movements, causing earthquakes.
C. Are fold mountains still forming on Earth?
- 1) Yes, as long as there are plate movements, fold mountains will form from the compressional forces.
- 2) No, the current plate movements are too insignificant to form fold mountains.
- 3) No, the plates are moving in the wrong way.
D. The surface of the earth will:
- 1) keep changing as plates keep moving
- 2) remain the same until the end of the world
- 3) slowly sink beneath the water surface
E. Where is the mantle found?
- 1) Between the crust and the core.
- 2) The innermost part of the Earth.
- 3) The outermost part of the Earth.
F. Which is the hottest part of the Earth?
- 1) The mantle
- 2) The core
- 3) The crust
G. Why are settlements still found near volcanoes?
- 1) To facilitate the study of volcanoes, and to send out immediate warnings to others in the near vicinity when the volcano show any signs of erupting.
- 2) To reap the benefits of volcanos, like the fertile soil from pyroclastic flows and lava for rich harvest, and minerals for mining.
- 3) People are unaware of the dangers of living near volcanoes.
H. What is a shield volcano made of?
- 1) Basic lava
- 2) Acidic lava
- 3) Ash and cinders
I. What are the effects of an earthquake measuring 7 on the Richter scale?
- 1) Wide cracks appear on the ground, damages buildings and landslides.
- 2) Concrete structures destroyed, complete destruction of a settlement.
- 3) Objects drop and vibration is felt by most.
J. How are plates moved?
- 1) By convection currents in the Mantle
- 2) By compressional forces
- 3) By the eruptions of lava from volcanos.
K. Where can coal only be formed?
- 1) warm and humid places
- 2) cold places like Antarctica
- 3) underwater
L. How do we reduce the effects of earthquakes?
- 1) Build settlements on softer ground and high areas such as mountains.
- 2) Proper planning and siting of settlement, construct flexible steel structures
that sway with ground movement, install automatic shutoff systems and conduct earthquake drills.
- 3) Build settlements of complete steel structures.
M. What can be formed at a convergent boundary?
- 1) Acid lava volcano
- 2) Shield volcano
- 3) New crust
N. What happens at divergent boundaries?
- 1) Sea floor spreads and magma rises up to fill the gap, forming oceanic ridges and submarine volcanoes.
- 2) Magma rises up and heat up the surrounding water to form tsunamis.
- 3) A gap is formed and surrounding water rushes in to cool the magma
into a lower layer of crust.
O. What is the structure of the earth most like?
- 1) a watermelon
- 2) an orange
- 3) an apple
