Earth Science
CA review 3rd quarter
| Question | Answer |
|---|---|
| What two elements make up the earth's atmosphere? | Nitrogen and Oxygen |
| What can water vapor in the atmosphere become? | Clouds and rain |
| When water changes from gas to a liquid due to cooling it is called what? | Condensation |
| What do we call tiny particles (dust, pollen) in atmosphere that help form clouds? | Condensation nuclei |
| What is the type of cloud formation when moist winds are lifted over mountains? | Orographic lifting |
| The temperature to which air must be cooled reach saturation is called what? | Dew point |
| What do we call the effect of the rotation of the earth's effect on Global wind patterns? | Coriolis effect |
| What basic wind system impacts weather in Missouri? | Prevailing Westerlies |
| What causes weak winds at the Horse latitudes (30*)? | Sinking air |
| What kind of front is cold, dense air that replaces warm air? | cold front |
| What kind of front is advancing warm air that displaces cold air? | warm front |
| What two factors determine relative humidity? | Air temperature and water vapor |
| What three things are required for thunderstorms to form? | moisture, unstable atmosphere, rising air |
| what kind of weather do you associate with low pressure systems? | cloudy |
| What is latent heat? | Heat stored in water vapor released during condensation |
| What do we call an extremely powerful thunderstorm that has intense rotating updrafts? | Super cells |
| What time of year do Tornadoes typically occur and why? | Spring, greatest difference in temperatures between polar and tropical air masses |
| What causes the intense updrafts and downdrafts that are present in severe thunderstorms? | Unstable air caused by temperature differences between upper and lower part of a storm |
| What causes lightning? | Electricity caused by rapid rush of air in a cumulonimbus cloud |
| What three factors are needed for hurricanes to form? | Warm ocean water, low pressure disturbance, release of latent heat |
| What is a storm surge? | Mound of water driven towards coast by high winds (such as a hurricane) |
| What is the sequence of hurricane development? | Tropical disturbance, depression, storm, hurricane |
| What is wind chill factor? | When the effects of cold air are worsened by the strength of the wind |
| What conditions would threaten human health and safety in regards to Heat Index? | Continental, 95* heat, above 60% relative humidity |
| What do we call the circular rising and falling of hot and cold air? | Convection |
| What causes Sea breeze thunderstorms? | cool moist air from water meets warmer air on land |
| The method of heat transfer that brings us energy from the sun? | Radiation |
| What type of climate is located in between the polar and tropical zones and is characterized as having violent weather changes with extreme summer and winter temperatures | Continental |
| Two climates at the same latitude may differ due to what factor? | Proximity (how close they are) to water |
| What kind of temperatures may you see when there is a cycle of low sunspot activity | Cold temperatures |
| When earth's orbit is elliptical it comes closer to the sun. What effect does this have on average temperatures? | Warmer temperatures |
| Volcanic eruptions that put large amounts of dust into the air and blocking energy from the sun would have what effect on global temperatures? | cooler/lower temperatures |
| The amount of energy that the atmosphere absorbs is affected by what gas? | Carbon Dioxide |
| When we burn fossil fuels, how does that effect global temperatures? | Global warming, energy from sun is trapped and reflected back to earth |
| If global warming continues, what is expected to happen | Average global temperatures will continue to increase |
| What is the expected outcome on sea levels if Global warming continues? | Sea levels will rise |
