A geologist is studying an area where earthquakes are likely to occur. What might the geologist expect to see after an earthquake?

• The streams’ directions have changed after the formation of a hot spot in Earth’s crust.

• The direction of the water flow in the streams has changed as a result of a change in the slope.

• The streams on one side of the fault have shifted in relation to the streams on the other side of the fault.

• Additional streams have formed on both sides of the fault as a result of new faults forming in Earth’s crust.

A sharp, jagged mountain becomes smoother over time. Which of these is most responsible for this change?

• deposition

• weathering and erosion

• movement of continents

• collisions between continental plates

Which area most likely has the greatest number of fast, large-scale changes?

• along seashores

• at high elevations

• near magnetic poles

• near plate boundaries

A mountain range is forming as a result of moving tectonic plates. In which of the Major Earth Systems are these formation taking place?

• biosphere

• geosphere

• atmosphere

• hydrosphere

Which type of change best describes folded mountain belts that sometimes form at plate boundaries?

• a slow, large-scale change

• a slow, small-scale change

• a fast, large-scale change

• a slow, small-scale change

Which geologic evidence could be the result from an asteroid impact on Earth’s surface?

• alternating layers of lava and volcanic ash erupted from a volcano

• fossils that show a steady rate of evolution in a certain type of organism

• petrified trees that have tree rings showing several years of stunted growth

• ice cores that show a gradual change in the carbon dioxide content of the atmosphere

Early in the history of geology, scientists debated different views of how geologic processes worked. Which statement explains how scientists generally view geologic changes or processes today?

• Earth’s surface is reshaped only through slow, gradual geologic processes.

• Early in Earth’s history, most geologic change was sudden, but now it’s mostly slow.

• Some geologic processes happen quickly, while others happen over millions of years.

• Geologic changes that reshape Earth’s surface only occur in sudden, devastating events.
