How big is the earth around the equator and poles? ✔Correct Answer-25,000 Miles
How do we know that the Earth consists of different layers? ✔Correct Answer-by studying the
propagation of seismic waves that detect differences in density
surface waves ✔Correct Answer-seismic waves that travel along the Earth's surface
body waves ✔Correct Answer-seismic waves that travel through the Earth's interior
S waves (secondary waves) ✔Correct Answer-Seismic waves that vibrate up and down and
side to side
P waves (Primary waves) ✔Correct Answer-a type of seismic wave that involves alternating
compression and expansion of the material through which it passes (slinky)
The inner core of the earth is made of? ✔Correct Answer-Solid Fe and Ni (Solid Iron)
Are there other oceans in our solar system? ✔Correct Answer-Yes, there are other liquid, salty
oceans
What are two types of crust? ✔Correct Answer-oceanic and continental
How thick is the continental crust? ✔Correct Answer-35 km
How thick is the oceanic crust? ✔Correct Answer-6 km
Isostasy ✔Correct Answer-is the state of gravitational equilibrium between Earth's crust and
mantle such that the crust "floats" at an elevation that depends on its thickness and density.
If I drop several blocks of wood into a bucket of water, which block will float higher? ✔Correct
Answer-A thick block made of light wood
Oceanic trenches are most abundant in the ✔Correct Answer-Pacific Ocean

The continents slide over ocean floor
Slow spreading oceanic ridges: ✔Correct Answer-Are tall and narrow with well-defined
central rift valleys
Will California "fall into the sea"? ✔Correct Answer-No, it is a transform fault so there is no
separation
