| Question | Answer |
|---|---|
| How old is the earth? | 4.5 billion years old |
| What gas makes up the largest percent of today's atmosphere? | Nitrogen |
| What gas made up the largest percent of the atmosphere's gases when Earth was first formed? | Carbon Dioxide |
| What is the hypothesis that states that Earth and Theia collided, forming the Earth & Moon? | Giant Impact Hypothesis |
| Oxygen was first infused into the atmosphere by what organism? | cyanobacteria |
| Could animal life as we know it existed in the early atmosphere? | No |
| What three solids are part of earth's atmosphere? | pollen, dust, salts |
| What layer of the atmosphere is where satellites reside? | Exosphere |
| What layer of the atmosphere is where the ozone layer resides? | Stratosphere |
| In what layer of the atmosphere do we live? | Troposphere |
| What layer of the atmosphere is warmest and thickest? | Thermosphere |
| List the layers of the atmosphere in order from ground up. | Troposphere, Stratosphere, Mesosphere, Thermosphere, Exosphere |
| What region of the atmosphere contains charged particles that create the Northern Lights and the light of meteors. | ionosphere |
| The ozone layer absorbs much of what type of radiation? | ultraviolet |
| What human-produced substance depletes the ozone layer by destroying the molecules? | chlorofluorocarbons (CFCs) |
| Coal, oil, gas, and other fossil fuels are burned to produce what greenhouse gas? | carbon dioxide |
| The atmosphere helps to keep the earth's surface warm. What is the name of this effect? | greenhouse effect |
| Name the five greenhouse gases | Carbon dioxide, nitrous oxide, CFCs, methane, water vapor |
| Where is the largest hole in the ozone layer? | Antarctica |
| What are the three types of energy transfer in the atmosphere? | radiation, conduction, convection |
| What type of energy transfer is done through rays & waves? | radiation |
| What kind of energy transfer is through direct contact? | conduction |
| What kind of energy transfer is the flow of liquid or gas from areas of high density (cool) to areas of low density (warm)? | convection |
| What kind of breeze blows from the sea during the day? | sea breeze |
| What kind of breeze blows from the land toward the sea at night? | land breeze |
| What is a region of warm, rising air called? | Low pressure system |
| What is a region of cool, sinking air called? | High pressure system |
| What tool is used to measure air pressure? | barometer |
| What tool is used to measure humidity? | psychrometer |
| Will molecules moving closer together be more or less dense? | more dense |
| Is there greater air pressure in the Troposphere or in the Mesosphere? | Troposphere |
| The equator receives more or less insolation than the polar regions? | more |
| What is the reason for lower insolation with increasing latitude? | The curve of the earth's surface |
| The day-to-day changes in atmospheric conditions. | weather |
| The typical weather patterns of a given location, averaged over many years. | climate |
| All of earth's waters on the surface and in the atmosphere. | hydrosphere |
| Water changing from liquid to gas. | evaporation |
| Water changing from gas to liquid. (forming clouds, dew) | condensation |
| Water leaving the atmosphere in the form of rain, snow, sleet, etc. | precipitation |
| Water flowing on the earth to the sea. | runoff |
| Water flowing into the ground, but still toward the sea. | infiltration |
| Water evaporating from plant's leaves through respiration. | transpiration |
| The four major factors affecting climate | latitude, elevation, proximity to water, position of mountains |
| Three major climactic zones. | Polar, Temperate, Tropical |
| Climate where temperatures are always cold, little sunlight in winter, and long days during summer. | Polar climate |
| Climate where there are four seasons and temperatures are moderate. | Temperate climate |
| Climate nearest the equator. | Tropical climate |
| What instrument measures wind speed? | anemometer |
| Lines connecting regions of the same temperatures on a map. | isotherms |
| Lines connecting regions of the same pressure on a map. | isobars |
| The amount of moisture in the air compared to what the air can hold. | relative humidity |
| The temperature at which water vapor condenses at the same rate as evaporation. | dew point |
