What does altitude mean?
Altitude means how high land is above sea level.
How much degrees celcius does the tepreture drop for every___meters of altitude?
Temperature falls by about 1°C for every 100 metres.
Why do very high mountains often have snow on them, even in summer?
Because the higher above sea level a place is, the cooler it is!
Why do places have different climates?
Ocean currents are movements of warm or cold water around the oceans. Ocean currents can raise or lower the temperatures of coastal areas.
What does latitude mean?
Latitude means how far north or south a place is from the equator.
What is the factor of climate?
Latitude is the main factor which affects climate.
True or False
Places on or near the equator have higher temperatures.
true
Places that are further away from the equator are cooler.
Does the shape of the earth affect dhow the sun rays heats diffrent areas?
Yes, the earth is a globe and this affects how different areas are heated by the Sun’s rays.
why are smaller areas on the equator more warm than other areas?
Because the sun rays hit smaller areas. This makes those areas warmer
Why is the polar areas cooler than the areas in the equators?
Because in the equator the sun rays that go through it is shining at a smaller area because the middle of the earth (equator) is very wide and the heat rays cant rap around it. But at a polar area since its the tips of the earth they’re easy to rap around by sunlight and so it does and most of it shines untill the range it can and stop around the tips of the globe ( the polar areas) and a little amount of sunlight is shining through the polar areas thus making them cooler.
What are the 6 main components of weather?
1) Weather
2) precipitation
3) cloudiness
4) atmospheric pressure
5) wind
6) humidity
What is temperature and what device do you use to measure it?
Weather temperature is how hot or cold the atmosphere is.
Temperature is measured with a thermometer
What unit of measurement of temperature does South Africa use
Celsius
What is atmospheric pressure AND what do you use to measure it
Atmospheric pressure is the WEIGHT of the atmosphere and it is measured with Barometer
high atmospheric pressure=?
High atmospheric pressures= cool temperature & clear skies
Low atmospheric pressure=?
Low atmospheric pressure = warmer weather, storms & rain
What is wind and what is it MEASURED with? (2 devices)
Wind is the movement of air.
An anenometer measures wind speed
Wind vanes measure wind direction
How does wind form?
Wind forms because of differences in temperature and atmospheric pressure between nearby regions
What is humidity and what is it MEASURED with?
Humidity is the amount of water Vapor in the air.
It is measured with a HYGROMETER
Does colder or warmer air hold more water?
Warmer air holds more water
What is precipitation AND what is it measured with?
Precipitation is any liquid or ice that forms in the atmosphere.
It is measured with a rain gauge
Describe clouds and what they do.
Clouds produce precipitation (rainfall/ snow) they come in different shapes.
What does weather mean?
What does weather mean
Weather is the temporary conditions of the atmosphere
What is climate?
Climate is the long-term pattern of weather in an area.
What are types of climate?
Polar and tropical wet climates
What are the five components of climate
Atmosphere
Cryosphere
Biosphere
Topography
Hydrosphere
