9. The diagram below shows the result of leaving an empty, dry clay flowerpot in a full container of water for a period of time. The water level in the container dropped to level A. The top of the wet area moved to level B.
Level B is higher than level A because water
- (1) is less dense than the clay pot
- (2) is more dense than the clay pot
- (3) traveled upward in the clay pot by capillary action
- (4) traveled downward in the clay pot by capillary action
10. Which weather condition most directly determines wind speeds at Earth’s surface?
- (1) visibility changes
- (2) amount of cloud cover
- (3) air-pressure gradient
- (4) dewpoint differences
11. Which statement best explains why an increase in the relative humidity of a parcel of air generally increases the chance of precipitation?
- (1) The dewpoint is farther from the condensation point, causing rain.
- (2) The air temperature is closer to the dewpoint, making cloud formation more likely.
- (3) The amount of moisture in the air is greater, making the air heavier.
- (4) The specific heat of the moist air is greater than the drier air, releasing energy.
12. The two elements that make up the largest percentage by mass of Earth’s crust are oxygen and
- (1) silicon
- (2) potassium
- (3) hydrogen
- (4) nitrogen
13. The weather instrument below can be used to determine relative humidity.
Based on the temperatures shown, the relative humidity is
- (1) 19%
- (2) 2%
- (3) 33%

18. What is the origin of fine-grained igneous rock?
- (1) lava that cooled slowly on Earth’s surface
- (2) lava that cooled quickly on Earth’s surface
- (3) silt that settled slowly in ocean water
- (4) silt that settled quickly in ocean water
19. Why does the oceanic crust sink beneath the continental crust at a subduction boundary?
- (1) The oceanic crust has a greater density.
- (2) The oceanic crust is pulled downward by Earth’s magnetic field.
- (3) The continental crust has a more mafic composition.
- (4) The continental crust is pulled upward by the Moon’s gravity.
20. Based on fossil evidence, most scientists infer that
- (1) life has not changed significantly throughout Earth’s history
