We have been talking with the Higher class today about the Biosphere section of work. We completed soils back in September but are now coming to complete the course by studying psammoseres (sand dune systems.) Some of the terminology was new and over the next few lessons we will be looking at the specific conditions under which these seres develop. This links in with the fieldwork we will complete next week.
The seres mentioned today included hydrosphere, lithosere, xerosere, psammosere and of course halosere ( hence the angel clue). Can you recall the meaning of all the terms ?
The link below will take you to a fantastic powerpoint shown at the Dalkeith Pupil Conference in March about psammoseres
