Which evidence recorded at seismic stations following an earthquake supports the inference that Earth’s interior changes from solid rock to molten iron and nickel at the mantle-core boundary?

• P-waves arrive earlier than S-waves.

• P-waves and S-waves are both recorded at all stations.

• Only S-waves are recorded at all stations.

• Only P-waves are recorded on the opposite side of Earth.

What are the inferred pressure and temperature at the boundary of Earth’s stiffer mantle and outer core?

• 1.5 million atmospheres pressure and an interior temperature of 4950°C

• 1.5 million atmospheres pressure and an interior temperature of 6200°C

• 3.1 million atmospheres pressure and an interior temperature of 4950°C

• 3.1 million atmospheres pressure and an interior temperature of 6200°C

Many scientists infer that one cause of the mass extinction of dinosaurs and ammonoids that occurred approximately 65.5 million years ago was

• tectonic plate subduction of most of the continents

• an asteroid impact that resulted in climate change

• a disease spreading among many groups of organisms

• severe damage produced by worldwide earthquakes
