1. During convection currents in fluid, what happens to the Movement
of fluid when heat source is being applied?
A. change direction
B. continue to move at the same rate as before
C. eventually stops
D. speed up
2.
What part of the Earth's Layer do scientist think that convection currents flow?
A. core
B. crust
C. lithosphere
D. mantle
3. What cause the movement of Earth's plates based from most geologists?
A. conduction
C. earthquakes
B. convection current in the mantle D. Earth's magnetic field
4. What do you call the event in which the lithospheric plates move away from
midocean ridges cooled and eventually become more dense than the
underlying hot mantle, causing the plate to move?
A. ridge push
C. thermal convection
B. slab pull
D. trench suction
5. What do you call the hypothetical force, caused by the horizontal spreading of
the near-surface asthenosphere at constructive margins, which is thought to
be one of the two main driving forces for the movement of lithospheric plates?
A. ridge push
C. thermal convection
B. slab pull
D. trench suction
6. How does sea floor spreading occurs as observed in the convection current that
occur underneath the crust?
A. earthquakes break apart the ocean floor
B. molten material beneath Earth's crust rises to the surface
C. new materials is being added to the asthenosphere
D. sediments accumulate at the area of spreading
7. What kind of differences in the hot, plastic like rock in the asthenosphere that
causes the plates to rise toward the Earth's surface?
A. composition B. density
C. magnetism D. composition
8. What characteristics of the asthenosphere that help explains the evidence of
crustal-plate motion?
A. ability to absorb heat energy C. magnetic properties
B. ability to deflect solar wind D. semiliquid physical state​
