Types of rainfall

There are three common types of rainfall, all of which occur in Spain. All have the common theme of air being forced to rise.
As air rises it cools it cannot hold as much moisture as it could when it was warmer. Eventually the rising air reaches a point where it is 100% saturated, in other words it cannot hold any more water. This is called dew point, and it is above this point that condensation occurs.
Condensation is the process by which the water vapour (a gas) held in the air is turned back into water droplets (a liquid), which fall as rain.
Very common in areas where the ground is heated by the hot sun, such as the Tropics. This is why those areas experience heavy rainfalls most afternoons. The United Kingdom does experience some convectional rainfall during the summer, particularly in the South East of the country.
Convectional rainfall occurs when:
  • The surface of the earth is heated by the sun.
  • The warm surface heats the air above it. Hot air always rises so this newly heated air does so.
  • As it rises the air-cools and begins to condensate.
  • Further rising and cooling causes a large amount of condensation to occur and rain is formed.
Convection tends to produce towering cumulo-nimbus clouds, which produce heavy rain and possible thunder and lightning.

The United Kingdom experiences a lot of frontal rainfall, as it is associated with the movement of depressions over the country, which are described in more detail elsewhere in this topic.
Frontal rainfall occurs when:
  • Two air masses meet, one a warm air mass and one a cold air mass.
  • The lighter, less dense, warm air is forced to rise over the denser, cold air.
  • This causes the warm air to cool and begin to condense.
  • As the warm air is forced to rise further condensation occurs and rain is formed.
  • Frontal rain produces a variety of clouds, which bring moderate to heavy rainfall.

This is also called orographic rainfall, which is very common in the United Kingdom, especially on the West coast since the prevailing weather comes from that direction.
Relief Rainfall occurs when:
  • The prevailing winds pick up moisture from the sea as they travel across it, making the air moist.
  • The moist air reaches the coast and is forced to rise over mountains and hills.
  • This forces the air to cool and condense, forming clouds.
  • The air continues to be forced over the mountains and so it drops its moisture as relief rain.
  • Once over the top of the mountain the air will usually drop down the other side, warming as it does so. This means it has a greater ability to carry water moisture and so there is little rain on the far side of the mountain. This area is called the rain shadow. ( link to this material)

Environmental Problems´ Investigation: How to Save the Polar Bear?

We will go to make a Power Point about one  environmental problems: How we can to save the Polar Bear. You can look for ideas about the Enviromental Problems   in  your book, pag 64-65 or in these links:

 To know more about the Polar Bear use this link or  this.
 To know more about Polar bear and Climate Change.

Use the Drive to make these presentations. Work in groups of 2 people. 
Every presentation have different points:
  • Global Environmental problems, 
  • Polar Ecosystem, 
  • How affect the environmental problems to the Polar bear, 
  • Solutions to save the  Polar Bear, ....
Every presentation need use nice pictures to show the problems and impress our thoughts.

    Eart 100 million Years from now

    Practicing maps

    To learn physical map we need practice

    How Noth America go its shape

    Continents, countries, and even mountain ranges didn't always look the way they look now. Millions of years ago, every continent had a different shape. The force that changes continents and mountains is called tectonics, and each continent sits on a tectonic plate.

    Read pages 28 and 29 in the textbook, and answer the questions.
    Also think about why tectonic plates, volcanoes, and earthquakes are connected. link

    After watching the video, answer:
    • What happens when one plate goes underneath another? 
    • What did the continents look like  millions of years ago? 
    • What does "rift" mean? 
    • Name the different tectonic plates in this region

    • Cardinal Points: we use it to establish direction. The principal cardinal points are north, south, east and west.
    • Graphic scale: It is the way to relate the reality with the map. It is a bar divided into equal segments (1 cm).
    • Longitude: It is measured by using the meridians which start at the prime meridian.
    • Meridian: It  is a semicircle which go from one pole to the other.
    • Prime meridian: It is the point of reference for other meridians. It divides the Earth into two hemispheres.
    • Compass: It is an instrument with a magnetic needle which always points north.
    • Hemisphere: It is each part of Earth dividing for prime meridian (the western hemisphere and the eastern hemisphere) or for the equator (the northern hemisphere and the southern hemisphere).
    • Numeric scale: It is expressed as a fraction. The numerator represents a unit on the map. The denominator represents its size in the real world.
    • Political map: It gives information on political organisation, such as international or regional frontiers.
    • Thematic map: It gives information on particular subjects, such us climate or vegetation.
    • Geographical coordinate: They are latitude and longitude. It´s indicate the exact location of a place on the Earth.
    • Latitude: It is measured by using the parallels which start at the equator.
    • Parallel: It is a circle which is perpendicular to the meridian.
    • Physical map: It gives information on relief, and show features such as rivers.

    Different ways of representing the Earth

    Look at this aerial photograph of the United States. Answer these questions in your notebook or  by e-mail.

    • What features can you see in this photograph?
    •  Can you see the area clearly? Can you see details or just a general view?
    •  What is the purpose of aerial photographs? Where are they taken from?
     This map shows the same part of the Earth as the photograph. Answer these questions.

    • Is the map identical to the photo?
    • Which countries are on the map?
    • Are aerial photographs useful in making maps? Why?

    Types of maps

    There are many types of maps.  Today, we will look at relief maps that show topography, population maps that show density, and different types of thematic maps.

    Look at the thematic maps slide show.  What does each map show us?
