| Radioactive dating of Moon rocks brought back by Apollo astronauts showed the age of the moon to be __. | 4.5 billion years |
| Which lunar phase occurs 2 weeks after a new moon? | full moon |
| What landform is made where oceanic crust sinks at a convergent boundary? | deep ocean trench |
| What causes the movement of air? | differences in air pressure |
| What is the cause of differences in air pressure? | unequal heating |
| Changing seasons on Earth are produced by changes in the AMOUNT & DIRECTNESS of ___. | sunlight |
| The amount & directness of sunlight on Earth changes throughout the year due to ___. | Earth's 23.5 degree axis tilt |
| Which type of crust is thicker but less dense? | continental crust |
| Which boundary is produced by the stress force tension? | divergent boundary |
| Which landform is produced by diverging oceanic crust? | midocean ridge |
| What process returns oceanic crust to the mantle? | subduction |
| Warm surface currents form near ___ and flow towards ___. | the equator; the poles |
| Which type of current affects coastal climates? | surface currents |
| Faster wind speeds & stronger storms occur between air masses that have greater differences in ___. | temperature |
| Air masses are classified by ___. | temperature & humidity |
| When are tornadoes most likely to occur? | spring & early summer (April, May, June) |
| Hurricanes are most likely to occur during which 5 month period? | June 30 - November 30 |
| Land breezes occur during ___ because land heats up & cools off ___ than water. | nighttime; faster |
| Identify the local wind being described: rising warm air over land produces low pressure, so higher pressure air moves from the water to land. | sea breeze |
| The climates of coastal areas typically have steady temperatures, and the climates of inland areas typically experience more temperature extremes. This is due to the stabilizing effects of ___. | surface currents |
| Hurricanes lose energy over ___ and ___. | land; cooler ocean water |
| What meteorological feature is common among thunderstorms, tornadoes, and hurricanes? | low pressure produced by rising warm, humid air |
| The idea that many geologic features & events are caused by the constant, slow motion of large pieces of Earth's crust is ___. | the theory of plate tectonics |
| What is the most important agent of weathering? | water |
| What is the most powerful agent of erosion? | moving water |
| The water cycle & the movement of air in Earth's atmosphere are both caused by ___. | the Sun |
| Earth's longest mountain chain is ___ & is located at ___ boundaries. | the midocean ridge; divergent |
| Which boundary type produces volcanic mountains, very strong earthquakes, and tsunamis? | convergent boundary |
| Lithospheric plates move due to ___ in ___. | convection currents; asthenosphere |
| The idea that all geologic change on Earth is caused by slow but constant processes is known as ___. | uniformitarianism |
| The idea that all geologic change on Earth is caused by sudden, devastating events is known as ___. | catastrophism |
| What is the current scientific thinking about the cause(s) of geologic change? | MOST change is caused by gradual processes, but SOME change is caused by catastrophic events. |
