Soil in Barbados

What is soil?

  • Watch the two animations at



Task: Describe what soil is made from?

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.

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

How are soils different?

  • Their texture depends on the mix of clay, silt and sand in them.

The structure of the soil

Other differences

  • pH – acid or alkali

  • Water content –

  • Nutrient level

  • Organisms in it

Is there a pattern of world Soils?

Can you see any link to this?

Or to this map of climate zones?

Longer Answer Task

  • From looking at the maps of climate, vegetation and soils, describe any patterns that you see and try and explain them

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

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

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


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.
