Scientist suggest that the movement of Earth's liquid iron core results in electrical currents. These currents would then result in Earth's magnetic field. Recent satellite data suggest that the strength of Earth's magnetic field has weakened by about 3.5 percent in some areas. In other areas, Earth's magnetic field strength has increased by about 2 percent. Which statement best explains the differences in Earth's magnetic field strength based on the movement of Earth's liquid iron core?
The movement of Earth's liquid iron core stopped in both locations.
The movement of Earth's liquid iron core changes direction in some locations.
The movement of Earth's liquid iron core is the same in all locations
The movement of Earth's liquid iron core increased speed in both locations.

Scientist are planning an investigation to collect evidence to help predict future magnetic pole reversals of Earth's magnetic field. Using information from figure 3, describe how scientists can collect data on changes in Earth's magnetic poles and explain how the data can be used to predict future magnetic pole reversals.
Scientist can use the ocean floor rocks to measure the amount of (force/time) between each change in (time/direction) of the magnetic poles.

Scientist claim that tree growth glowed during the period from AD 1100 to 1300, resulting in thinner tree rings. Based on the information in Table 1, which statement can best be used as evidence to support the claim?
More than 40 percent of the west in typically affected during dry periods.
The average precipitation in the west significantly increased during this period.
A large percentage of the west was affected by dry conditions during this period.
The average precipitation in the west increased after AD 1300.
