G10 Earth Science

How many MAJOR segments are there in the Earth’s lithosphere?

• eight

• nine

• seven

• six

Which of the following is NOT a minor tectonic plate?

• African plate

• Caribbean plate

• Nazca plate

• Philippine plate

Which of the following is NOT a sub-layer of the mantle?

• asthenosphere

• Mohorovicic Discontinuity

• lower mantle (mesosphere)

• outermost rigid layer of the mantle

What type of plate boundary interaction is taking place between Philippine and Pacific plate?

• oceanic-oceanic

• continental-continental         

• continental-oceanic

• continental-crustal

Which shows the correct type of plate boundary and interaction of forces?

• convergent-pulling    

• divergent-colliding    

• divergent-pushing

• transform fault-past each other

What geologic feature is present on the three types of plate boundaries?

• earthquake

• mountains

• rift valleys      

• volcanoes

What do you expect to find at the mid-ocean ridge?

• . reverse faults

• very ancient rocks

• relatively young rocks

• thick accumulation of sediments

Most of earth’s earthquakes, volcanoes, and mountains occur and can be found:

• in the Himalayas        

• at plate boundaries    

• at volcanic arcs

•  in the center of continents

Complex mountain system such as the Himalayas are the result of:

• hot spots

• oceanic-oceanic convergence

• transform faults

• continental-continental convergence

The motion of the convection current in the mantle beneath the Atlantic Ocean appears to be mainly making the ocean basin _________________________.

• deeper

• narrower

• shallower

• wider
