1. Soil in Barbados From MYP unit – factors affecting the physical Environment of Barbados – Codrington School Piers Tainsh

2. What is soil? Watch the two animations at http://whs.moodledo.co.uk/file.php/1365/E cosytems%20and%20Soil/What%20is%20So il.swf http://whs.moodledo.co.uk/file.php/1365/E cosytems%20and%20Soil/What%20is%20So il.swf http://www.montereyinstitute.org/courses/ AP%20Environmental%20Science/course%2 0files/multimedia/lesson51/animations/4c_ soil_profile.html http://www.montereyinstitute.org/courses/ AP%20Environmental%20Science/course%2 0files/multimedia/lesson51/animations/4c_ soil_profile.html Task: Describe what soil is made from?

3. What is soil made of made up of a mixture of organic material and minerals. organic matter comes from dead plants the minerals come from the rocks underground. These rocks are called bedrock. Because the plants grow on top of the soil and the rocks are found underground, soil is made up of layers.

4. The Soil Profile There are different sections O and A – the organic layers made from broken up dead material to make humus B – the topsoil a mix of humus and minerals broken down by weathering of rock C – weathered parent rock Below this is the rock. Task: Draw a labeled diagram of a Soil Profile

5. How are soils different? Their texture depends on the mix of clay, silt and sand in them.

6. The structure of the soil

7. Other differences pH – acid or alkali Water content – Nutrient level Organisms in it

8. Is there a pattern of world Soils?

9. Can you see any link to this?

10. Or to this map of climate zones?

11. Longer Answer Task From looking at the maps of climate, vegetation and soils, describe any patterns that you see and try and explain them Longer Answer Task From looking at the maps of climate, vegetation and soils, describe any patterns that you see and try and explain them

12. I notice that places with tropical soil have rainforest biomes this is because of the tropical-wet temperature levels

13. So What Should the Soil of Barbados be like if it was a Zonal Soil? What do you notice about this soil (a tropical latasol) Annotate a copy of this photo to show the A, B and C horizons

14. Soil in Barbados is Intrazonal In this case it is not climate or vegetation that is so important in creating the type of soil it is the rock - LIMESTONE Task: Take a picture of a profile of Barbados soil. Import it onto a graphics package and annotate it with explanations. Upload it onto your Google map.
