SCIENCE 10 Q1 REVIEW

What do you call the theory of moving lithospheric plates?

• tectonic plates

• plates

• plate boundaries

• plate tectonics

Which is TRUE about Earth's crust?

• Crust is divided into inner and outer core.

• Crust is made up of igneous rock only

• The crust moves fast every year that makes its segments collide from one another

• The crust is thickest in a part where a relatively young mountain is present and thinnest along the ocean floor.

You were asked to locate the epicenter of a recent earthquake. Which correct sequence of events should you follow?

• Determine the difference in the arrival time of S and P waves recorded from each of the seismological stations.

• Use the triangulation method to locate the center.

• Obtain data from three different seismological stations.

• Determine the distance of the epicenter from the station.

In the formula d=Td/8s X 100km, why is time difference (Td) divided by 8 seconds?

• The difference in arrival time is 8 s per 100 km.

• The scientist's favorite number is 8.

• The velocity of the P wave is 100km per 8s.

• Eight is a lucky number.
