A student makes this particle model of atoms that make up part of the bridge. The model shows the atoms when the bridge is at 18°C.

The student wants to make a new model to show the atoms when the bridge is heated to 23°C.

Which of the following changes should the student include in the new model?

• making the atoms bigger

• making the atoms a different shape

• making larger spaces between the atoms

• making chemical bonds between the atoms

Small earthquakes are relatively common near the Golden Gate Bridge, but major earthquakes occur less often. Major earthquakes only occur when a large amount of energy is carried by seismic waves.

Which of the following must be large for a major earthquake to occur?

• the speed of the seismic waves

• the frequency of the seismic waves

• the amplitude of the seismic waves

• the wavelength of the seismic waves
