• asthenosphere

• outer core

• inner core

Why is Earth’s outer core inferred to be a liquid?

• P-waves can pass through the outer core.

• P-waves cannot pass through the outer core.

• S-waves can pass through the outer core.

• S-waves cannot pass through the outer core.

Where is the thickest part of the Earth's crust?

• at mid-ocean ridges

• at transform faults

• under continental mountain ranges

• under volcanic islands

Compared to the oceanic crust, the continental crust is usually

• thicker, with a less dense granitic composition

• thicker, with a more dense basaltic composition

• thinner, with a less dense granitic composition

• thinner, with a more dense basaltic composition

The observed difference in density between continental crust and oceanic crust is most likely due to differences in their

• composition

• thickness

• porosity

• rate of cooling

The pressure at the interface between Earth's outer core and inner core is inferred to be

• 0.2 million atmosphere

• 1.5 million atmospheres

• 3.1 million atmospheres

• 3.6 million atmospheres

The inferred temperature and pressure of Earth's interior at a depth of 3,000 kilometers are approximately

• 1000°C and 0.5 million atmospheres

• 1000°C and 1.0 million atmospheres

• 5000°C and 1.5 million atmospheres

• 5000°C and 3.0 million atmospheres

Compared to Earth’s crust, Earth’s core is believed to be

• less dense, cooler, and composed of more iron

• less dense, hotter, and composed of less iron

• more dense, hotter, and composed of more iron

• more dense, cooler, and composed of less iron
