How does pressure change as you move from Earth’s surface to the inner core?

• Pressure is highest in the crust, then decreases steadily in the mantle and core.

• Pressure decreases as temperature increases in the mantle and core.

• Pressure increases steadily as the weight of rocks above increases.

• Pressure increases and decreases depending on the density of the rock layer.

What natural process or processes shaped this amazing rock?

• weathering and erosion

• deposition

• volcanic activity

• heat and pressure

A 2016 study found that nearly one-third of deaths in China are linked to outdoor air pollution. Smog sometimes closes schools and grounds airplanes. Hospitals are overwhelmed with patients struggling to breathe. Which of the following would improve outdoor air quality?

• use gasoline instead of biofuels

• increase the use of wind turbines

• decrease the use of geothermal energy

• increase ozone levels by using more CFCs

The geologic time scale is a record of the major geologic events and evolution of life. Its divisions are determined through evidence in the rock and fossil records. What might cause geologists to make changes to a period on the geologic time scale?

• the discovery of a new method of relative dating

• the discovery of an asteroid collision cooling Earth

• the discovery of a new species of dinosaur

• the discovery of a new unconformity in the rock record

What is the relationship between mountain building, volcanoes, and earthquakes?

• They mostly occur in the oceans and in the center of plates at land boundaries because of convection currents.

• They mostly occur at plate boundaries and are generated from eruptions that occur on land due to convection currents.

• They mostly occur in the oceans and change the sea floor by spreading apart to make new rock.

• They mostly occur at plate boundaries and are generated by plate motions from convection currents.

While drinking one day, a girl notices an odd illusion shown in the image below. The image illustrates how light is affected when passing through liquids and gases. Is sound affected the same way?

• Yes, because sound waves are also slowed by traveling through B.

• No, because sound waves travel faster when traveling through B.

• Yes, because traveling through D also makes sound waves slower.

• No, because traveling through D makes sound waves faster.
