| Question | Answer |
|---|---|
| Define, "Air Pressure" | the weight of air as it presses down |
| Define, "Atmosphere" | a layer of gases surrounding Earth |
| Define, "Troposphere" | lowest layer of the atmosphere it starts at sea level. |
| Define, "Stratosphere" | the second layer of the atmosphere which keeps the sun's harmful rays from harming the Earth |
| Define, "Mesosphere" | the third layer of the atmosphere the coldest temperatures of the atmosphere are found here |
| Define, "Thermosphere" | top layer of the atmosphere space begins at the top of this layer |
| Define, "Greenhouse Effect" | the process by which heat from the Sun builds up near Earth's surface and is trapped there by Earth's atmosphere |
| Define, "Weather" | the conditions of the atmosphere at a certain place and time |
| Define, "Nitrogen" | a gas that makes up the largest portion of air plans need it to grow |
| Define, "Oxygen" | the second most common gas in the air we need it to breathe |
| Define, "Carbon Dioxide" | a colorless odorless gas that helps hold heat to the Earth |
| Evaporation is the... | first part of the water cycle and the change of state from a liquid to a gas caused by the sun or heat |
| Condensation is the... | second part of the water cycle and the change of state from a gas to a liquid |
| Precipitation is the... | last part of the water cycle and its any type of form of water that fall from the clouds to Earth's surface |
| Define, "Water cycle" | the movement of water into the air as water vapor and back to Earth's surface as precipitation. |
| Define, "Water Vapor" | water in a gas form |
| What is a stratus? | Stratus is a cloud that stays at a low level and forms layered it usually means steady rain |
| What is a cumulus? | Cumulus is a cloud which is fluffy and fave flat bases usually means OK weather and forms low in the sky |
| What is a cirrus? | A thin feathery cloud made of ice crystals and they form high in the sky |
| What is a cumulonimbus? | A cloud that brings thunderstorms |
| Define, "Air mass" | a large body of air that has the same temperature, air pressure, and moisture throughout |
| Define, "Front" | the place where two air masses meet |
| Define, "Humidity" | the amount of water vapor in the air |
| What does a thermometer do? | measures temperature in degrees Celsius or degrees Farenheit |
| What does a rain gauge do? | measures the amount of precipitation that has fallen in an area |
| What does an anemometer do? | measures the speed of wind |
| What does a barometer do? | measures air pressure |
| What gases are the air made of? | Nitrogen, oxygen, etc. |
| The Troposphere is... | The first layer of the atmosphere and it starts at sea level. Where we live on the ground. |
| The Stratosphere is... | The second layer of the atmosphere. the Sun's powerful rays heat up this layer. |
| The Mesosphere is... | The third layer of the atmosphere the coldest temperatures of the atmosphere are here. |
| The Thermosphere is... | The fourth layer of the atmosphere and space begins at the top of this layer. |
| What are the three main factors that affect climate? | Altitude, latitude and bodies of water. |
| Hurricanes can... | Produce floods and strong winds. Along with, destroying houses and get people in danger. |
| When a cold front moves in... | Thunderstorms are being created. |
| Evaporation is... | The first part of the water cycle and water gets heated up and forms clouds. |
| Condensation is... | When the clouds form eventually the water vapor or clouds turns back into water. |
| Precipitation is... | Finally, the clouds get so heavy it uses the bathroom and empty's out it's bladder leaving us with either rain, sleet, hail, or snow. |
