| Question | Answer |
| What does climate mean? | The general weather of a place Ex: Northern Canada=Cold Southern Mexico=Warm |
| What is weather | Current atmospheric conditions even if the zone is usually in a different atmospheric condition. |
| How are particles positioned when the object is a)Solid b)liquid c)Gas | a) when solid, the particles are close together b)When liquid, the particles have some space, c)When a gas, the particles have a lot of space and move around a lot |
| What causes pressure? | Pressure is caused when particles re hitting the sides of a large container. The more they hit the sides, the more pressure there is |
| What are the key elements needed to form a cloud | -Dust particles -Water -Temperature or pressure changes |
| What is a cloud? | a cloud is water vapor that can only be seen when the water particles condense around a dust particle. |
| How does a cloud form? | When temperature or pressure decreases, air can't hold as much water so the small water droplets group together into larger droplets around the dust and becomes a cloud |
| How come clouds drop water in the form of rain? | as clouds go higher into the skies the air gets colder. The particles group closer together. Since the cloud cant hold that much heavy water it drops it in the form of rain. |
| What are the steps of a cloud forming? | 1) sun heats water, water evaporates, 2)water groups around dust particle 3)Cloud is formed 4)Cools down with altitude and rains And repeat |
| What do you use to show pressure in a map? | Isobars |
| How do you know if you are in a high or low pressure system | If you are in in a high pressure system the pressure will get higher towards the center. If you are in a low pressure system the pressure will get lower towards the center |
| Which way does low and high pressure wind go in the northern hemisphere? | low pressure wind will go counter-clockwise in the northern hemisphere high pressure will go clockwise in the northern hemisphere. |
| Which way do low and high pressure wind go in the southern hemisphere? | Low pressure wind will go clockwise in the southern hemisphere High pressure wind will go counter-clockwise in the northern hemisphere |
| if there is high pressure wind near low pressure wind what will happen? a) high will go towards low b) low will go towards high | a) High will go towards low |
| What does a weather front describe? | A front describes the boundary between two air masses with different temperature and/or water vapor content. |
| what do fronts mark | the boundary between two air masses |
| what is a warm front | it is when cold and warm masses collide and the warm is overtaking the cold rising over the cold because it is lighter |
| what is a cold front | a cold front is when a cold mass of air meets a warm one. The cold air is coming with greater force therefore lifts the warm air from underneath |
| what is a stationary front | a stationary front is when a cold and warm mass meet with equal force and stay in the same place like an endless battle between hot and cold |
| what is an occluded front | it is when a cold and warm front meet in the same place |
| what are the basic cloud types | -cirro-form -strato-form -cumilo-form -nimbo-form |
