How is temperature measured , and what do we use to express it?
It is measured with a thermometer, and we use Centigrade to express it.
What causes humidity?
evaporation of water from oceans, lakes, rivers, wetlands, and plants
What is used to measure atmoshperic pressure?
barometer
Where is the hot (tropical) zone? The temperate zones ? The polar zones?
hot (tropical) zone - between the Tropic of Cancer and the Tropic of Capricorn
temperate zones - between the tropics and the polar circles
polar zones - the poles
What is the order of events of the water cycle?
evaporation, condensation, precipitation
What are isotherms?
the lines that join areas with the same temperature
How are clouds formed?
the atmosphere cools and water vapor becomes liquid (condensation)
What factors affect atmospheric pressure?
altitude and temprature
Give an example of a country or region with hot (tropical) climates, temperate climates, and cold climates.
Answers may vary
How are polar bears being affected by climate change?
The ice caps where they live andhunt are melting.
What are the main climate zones?
hot zone (tropical), temperate zones, and polar zones
Describe the process of precipitation. What are three forms of precipitation?
Drops that form clouds get colder and increase in size and weight. When they are too heavy, they fall to the Earth´s surface. Three forms are rain, snow, and hail.
What does a weather map show?
atmospheric pressure at sea level
Why are there four seasons?
the inclination of the sun´s rays
What causes climate change and what are the negative effects of it?
Greenhouse gases from fossil fuels cause climate change. The negative effects are drought, starvation, and hurricanes.
What three factors affect why temperature is not the same everywhere? Describe how each factor affects temperature.
latitude - temperatures are higher near the equator and lower near the poles
altitude - temperatures are higher in low areas and lower in high areas
distance from the sea - the sea makes coastal climates milder
What three factors affect precipitation? Explain how.
latitude - there is more rain in regions near the equator
altitude - it rains more in the mountains
humidity - it rains more on the coast because oceans and seas are a source of humidity
What symbols are on a weather map? Describe them.
isobars - connect areas that have the same atmoshperic pressure
H - high pressure area
L - low pressure area
fronts - cold fronts and warm fronts
List the three climates in the hot (tropical) zone, the four climates in the temperate zone, and the two climates in the cold zones.
Hot zone: equatorial, tropical, hot desert
temperate zones: mediterranean, humid sub-tropical, oceanic, continental
cold zone: polar, mountain
Name each layer of the atmosphere and describe each.
troposphere - lowest level
hydrosphere - oceans, lakes , and rivers that cover 75% of Earth´s surface
stratosphere - the ozone layer
