Earth's Interior Quiz

The theory that the outer core of the Earth is composed of liquid material is best supported by

• seismic studies which indicate that shear waves do not pass through the outer core

• seismic studies which show that compressional waves can pass through the outer core

• density studies which show that the outer core is slightly more dense than the inner core

• gravity studies which indicate that gravitational strength is greatest within the core

Which zone of the Earth has the greatest density?

• crust

• mantle

• outer core

• inner core

In which region of the Earth's interior would material with a density of 10 grams per cubic centimeter most likely be found?

• outer core

• inner core

• crust

• mantle

The inference that a liquid outer core exists within the Earth is based primarily on the analysis of

• crustal rock samples

• the Earth's revolution

• seismic data

• core samples

The P-waves (compressional waves) from an earthquake travel through the Earth's

• crust, mantle, outer core, and inner core

• crust, only

• crust, mantle, and inner core, only

• crust and mantle, only

The density of Earth’s crust is

• less than the density of the outer core but greater than the density of the mantle

• greater than the density of the outer core but less than the density of the mantle

• greater than the density of both the outer core and the mantle

• less than the density of both the outer core and the mantle

Based on the passage and cross section, compared to the surrounding material, mantle plumes rise toward Earth's surface from the core-mantle boundary because they are

• hotter and less dense

• cooler and less dense

• hotter and more dense

• cooler and more dense

The igneous material along this mid-ocean ridge was found to be younger than the igneous material farther from the ridge. This fact supports the theory of

• superposition

• dynamic equilibrium

• crustal subsidence

• seafloor spreading

A piece of a plant in a classroom fishtank moved upward and across the tank, away from the water heater. When the plant reached the other side of the tank, it sank before moving back toward the heater. What type of energy transfer does this movement represent?

• convection

• refraction

• conduction

• radiation
