Weather Flashcards
What is evaporation?
Energy from the sun that changes water from a liquid to a gas (water vapour) in the atmosphere
What are the three stages of the water cycle?
Evaporation,
condensation,
percipitation
What is condensation?
As water vapour rises, it cools and condenses into tiny water droplets to form clouds
What is percipaitation?
Water is released from the clouds and returns to earth in the form of rain, sleet, snow or hail
What is a run off?
Water moves down-hill and across the land
What is the underground
Some water seeps into the ground, where it is stored in the rocks and in the soil
What are the factors that influence climates?
Latitude, distance from the sea, prevailing winds, aspect and altitude
What is latitude?
The angular distance north or south of the equator. The closer you are to the equator the warmer the place. The sun is high and concentrated on a smaller area of the earth
How does the distance from the sea effect the climate?
The sea heats up much more slowly than the land during the summer but the sea also takes longer to lose heat during winter. As a result coastal areas have cool summers and warm winters and inland areas have warm summers and cool winters
How does the prevailing winds influence the climate?
Since winds influence the temperature and percipitation it depends on what direction the wind comes from and if the wind comes came from the land or the sea
How does the aslect influence the climate?
The aspect is the direction that slopes face. If the slope faces the south the slope would be warmer because the sun’s rays strike the ground at a more direct angle
What is altitude?
This is how something is above sea level. The higher the place is the colder it is
What is the greenhouse effect?
When the greenhouse gases such as CFC’s, nitrous oxide, carbon dioxide and methane let heat in but prevent most of the heat from getting out. There used to be a balance between heat but now because of the greenhouse gases we use it causes global warming
Types of Rainfall
Relief rainfall
Convectional rainfall
Cyclonic rainfall
Cirrus cloud
High wispy clouds
