Weather and Climate 1
What is Precipitation? what are the forms of precipitation?
Precipitation is amount of water falling from the atmosphere. Rain, snow, sleet or hail
How do you instrument shows the direction of the wind?
wind vane or wind sock
How many types of climate around the world? give 5
desert (arid), polar, tropical, continental and temperate
Barometer measures? unit?
Air pressure Mb
What greenhouse gas is produced by the burning of fossil fuels?
2.Carbon Dioxide
What are the elements of weather?
Wind, temperature, atmospheric pressure, humidity, precipitation
What is the equipment used to measure humidity and unit of measurement?
Hygrometer and %
What instrument measures the air temperature? and units of measurement
Thermometer, oC/ oF
The distance a location is north or south of the equator is measured by its ?
Latitude
List four ways that cause carbon dioxide levels to increase
burning fossil fuels
deforestation
volcanic eruptions
cement covering
_____________ is the temporary state of the atmosphere over a short period of time.
Weather
What is a climate?
Climate is the average weather condition of a place over a long period of time. usually 30years
What happens to temperature as you go up in altitude?
The temperature decreases
What is altitude?
The height of a place above sea level.
Give 2 clues for climate change
Ocean sediments
Layers of ice sheets from snow.
True or False- Weather changes constantly.
True
True or False- the farther from the equator, the hotter the climate.
False. Places far from the equator are cooler but places close to Equator have hot climate
How do you find the density of a sample of salt water?
Get a small sample, find its mass and volume.
Divide mass by volume to get density
How does air move in a high pressure area? is it warm or cold?
Air moves down and out. It is cold (more dense and sinks)
A warm air mass meets the cold air mass, the warm air rises, and its water vapour condenses. clouds form, it rains.
what type of rainfall is described above?
frontal rainfall (cyclonic rainfall)
Explain the main difference between weather and climate
Weather is the atmospheric condition over a short period of time and climate is over a long period of time (average weather pattern of 30years)
What are four factors affecting climate?
Latitude(the main factor)
Altitude
Distance from the sea.
PREVAILING WIND DIRECTION, ocean current
What instrument measures precipitation? and unit of measurement
Rain gauge, Litre, mm
What type of weather is associated with a warm front?
A little drizzly that lasts for a few days, followed by warm air
Give 2 effects and solutions to climate change
Effects; flood, drought, heat waves, hunger,
Solutions; Afforestation, renewable energy, 3Rs, walking/use public transport
