Cards in this deck (21)
- 1What does climate mean?The general weather of a place
Ex:
Northern Canada=Cold
Southern Mexico=Warm - 2What is weatherCurrent atmospheric conditions even if the zone is usually in a different atmospheric condition.
- 3How are particles positioned when the object is a)Solid b)liquid c)Gasa) 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 - 4What 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
- 5What are the key elements needed to form a cloud-Dust particles
-Water
-Temperature or pressure changes - 6What is a cloud?a cloud is water vapor that can only be seen when the water particles condense around a dust particle.
- 7How 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
- 8How 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.
- 9What 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 - 10What do you use to show pressure in a map?Isobars
- 11How do you know if you are in a high or low pressure systemIf 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 - 12Which 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. - 13Which 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 - 14if there is high pressure wind near low pressure wind what will happen? a) high will go towards low b) low will go towards higha) High will go towards low
- 15What does a weather front describe?A front describes the boundary between two air masses with different temperature and/or water vapor content.
- 16what do fronts markthe boundary between two air masses
- 17what is a warm frontit is when cold and warm masses collide and the warm is overtaking the cold rising over the cold because it is lighter
- 18what is a cold fronta 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
- 19what is a stationary fronta 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
- 20what is an occluded frontit is when a cold and warm front meet in the same place
- 21what are the basic cloud types-cirro-form
-strato-form
-cumilo-form
-nimbo-form
