| Question | Answer |
|---|---|
| Isobar | a line on a map connecting points having the same atmospheric pressure at a given time or on average over a given period |
| Conduction | heat spreads through a substance when faster atoms and molecules collide with neighboring slower ones |
| Precipitation | rain, snow, sleet, or hail that falls to the ground |
| Front | he front end or advancing edge of an air mass that will soon replace the air mass that’s over a specific region |
| Humidity | the amount of water vapor in the atmosphere or in a gas |
| Condensation | the change of the physical state of matter from gas phase into liquid phase |
| Air pressure | the weight of air molecules pressing down on the Earth |
| Radar | a tracking system used to determine the location and velocity of a storm, clouds, precipitation |
| Latitude | imaginary lines that measure the distance north or south of the equator from 0° to 90° |
| Longitude | imaginary lines that measure the distance east or west of the prime meridian from 0° to 180° |
| difference between weather and climate. | Weather is a short-term condition while climate is the weather of a specific region averaged over a long period of time. |
| What Can Clouds Tell Us about Weather? | Predict weather in the near future. |
| What happened in the Activity 2.2: A Little Heat from Me to You experiment | The thermal energy from heat source was being conducted/transferred through the metal rod and the closer crisco ball stayed faster and the other ones travelled away. |
| How Do Differences in Temperature Affect Air Masses? | When the air is hot the air moves faster and is lighter. The molecules need more space. When the air is colder the air is denser and moves slower. The two different temperatures collide and create a storm. |
| Barometer | A barometer is a specific instrument used to measure the air pressure. |
| What Can Weather Maps Tell Us? | Maps can tell us the temperature, air, pressure, wind, cloud, cover, and precipitation. |
| Isobar Map | Air pressure is measured in millibars. The air pressure is in Mb therefore the air pressure is increasing and becoming denser/cooler and the air is becoming dryer. |
| difference between a low pressure and high pressure system. | Low: low pressure systems suck air into them so there can be equal pressure. High: High pressure systems have more air than their surroundings. |
