ES Hmwk; Earth's Interior

In developing a model of Earth's deep interior, most of the evidence was derived from

• deep wells

• mining operations

• observation of other planets

• seismic data

According to the ESRT, in which group are the zones of Earth's interior correctly arranged in order of increasing average density?

• crust, mantle, outer core, inner core

• crust, mantle, inner core, outer core

• inner core, outer core, mantle, crust

• outer core, inner core, mantle, crust

What evidence has been obtained concerning the existence of the Moho and Earth's mantle?

• satellite images

• well drillings

• exposures in deep canyons like the Grand Canyon

• refraction of earthquake waves

What is the relationship among density, temperature, and pressure inside Earth?

• as depth increases, density, temperature and pressure decrease

• as depth increases, density and temperature increase, but pressure decreases

• as depth increases, density increases, but temperature and pressure decrease

• as depth increases, density, temperature, and pressure increase

In which parts of Earth's interior would melted or partially melted material be found?

• stiffer mantle and inner core

• stiffer mantle and outer core

• crust and inner core

• asthenosphere and outer core

An earthquake occurs in city A. Recordings on a seismograph in city B show only the presence of P-waves. City A and B are opposite sides of Earth - 180 degrees apart. What does this information allow you to infer about the structure of Earth's interior?

How does the composition of the oceanic crust compare with the composition of the continental crust?

• the oceanic crust is mainly limestone, while the continental crust is mainly sandstone

• the oceanic crust is mainly limestone, while the continental crust is mainly granitic

• the oceanic crust is mainly basaltic, while the continental crust is mainly sandstone

• the oceanic crust is mainly basaltic, while the continental crust is mainly granitic

As one travels from an ocean shore to the interior of a continent, the thickness of Earth's crust generally

• decreases

• increases

• remains the same

The overall density of Earth is approximately 5.5 g/cm3. The average density of Earth's crust is between 2.5 g/cm3 and 3.0 g/cm3. What does this suggest about the density of Earth's core?
