AbstractAn outline is given of the Quaternary geology and geomorphology of Court Hill Col in Failand Ridge near Clevedon, Avon County, from observations made during the construction of the M5 Motorway.A glacial col-gully about 100 m wide and approximately 25 m deep is described. The col-gully, eroded through the Carboniferous Limestone, opens and deepens northward. Associated with the Col and the col-gully is a complex sequence of Quaternary deposits. Uppermost in the sequence is a layer of red sandy silt (cover sand) approximately 0.5 m thick, of periglacial origin, probably of Devensian (Weichselian) age. Largely confined to the col-gully are unstratified tills, stratified ice-contact deposits and glacio-lacustrine deltaic deposits. The glaciogenic deposits are up to 25 m thick. Boulders of about 8 Mg in weight have been observed.The geomorphology of the col-gully, and the stratification and composition of the glaciogenic deposits, demonstrate that an ice sheet at least 85 m thick had impinged against the south flank of Failand Ridge and was discharging immense quantities of water and sediment down an ice-contact slope through the Col into a small ice-marginal lake north of the col-gully. The ice sheet is regarded as being Wolstonian, or Anglian, in age.The precise origins of the col-gully and the interpretation of the glacial sequence are not yet completely clear. However, it is believed that the balance of evidence indicates that both the col-gully itself and the glaciogenic deposits represent a complex sub-, en- and pro-glacial sequence associated with the downwasting and division of an ice mass into two parts by the "emergence" of Failand Ridge. The possible extent and geomorphological implications of ice-sheet penetration into the Bristol area are briefly discussed.

SynopsisThe Quaternary features and deposits provide a record of the geological history of the past 18,000 years and only a few elements of the landscape, such as the glaciated rock platforms and cliffs of marine origin, can be ascribed to earlier times. Mainland ice almost certainly covered the islands during the last glaciation, its retreat being temporarily reversed or halted perhaps more than once. There was a final well-marked, but short-lived episode of valley glaciation some 10,000 to 11,000 years ago. Glacial deposits, raised beaches, periglacial features, landslips and the post-glacial accumulations of peat, shell sand and diatomite are discussed briefly.

This study was conducted based on the facts about the lack of maximal outcomes of learning English in almost all levels of education, especially in vocational school. Although English has been studied for many years, but the majority of students can not master English well, especially speaking. Many factors cause this phenomenon, and all parties should concern to work together to formulatebetter system and process of English learning at vocational school.The research was conducted at SMK Negeri 1 Pacitan, by taking the students of class XII as subjects research. The sample of this research consists of 94 students of Business Travel and Tourism,Network Computer Engineering, and Engineering Software classes. This research uses descriptive qualitative method. It is used to describe the students’ speaking competence, particularlyin presenting final task report. This research also identifies the internal and external functions to formulate a strategy to improve the students’s speaking competence. The results showed that based on the analysis of English speaking competency of SMK Negeri 1 Pacitan students, it can be concluded as follows: a). Based on the students absorption analysis of presenting final project report, shows that English competency level of students is in the category of “pretty”, with evidence of the studentsvalue average in presenting final project report is more than the passing grade value (7.50),it is 79.5. While the number of student, who passed the presentation test,is 66 students.So it can be obtained the percentage level of mastery learning students on the presentation test of final report is only 70.21%, and it is categorized “less”, because the percentage of students who passed this exam is still under 75%. b). While the analysis of the questionnaire can be scribed that the average overall score of 3.44 speaking competence components are categorized “pretty”, and it can be concluded that the level of competence of English speaking students generally categorized “enough”. Based on the level ofstudents’ English speaking competence , it can be formulated the strategies to increase its competence. They are: a). Maximizing the use of English as a language instruction and reducing the use of Indonesian, especially in the learning process, to improve English language competency, so that students can have the ability to explain the sequence of events and the students can pass the exam well. b). Having more English presentation activitiesin other topics to encourage the students’ bravery and self-confidence in speaking English, so that students have good Englishcompetence as preparation to getjobs or to continue their study at university.c). Having more exercise of using body language to improve the mastery of speech, and smooth attitude, so that students have good English competence,and they are able to compete in the global world in obtaining employment. d). And maximizing the use of school’s facilities by using various methods of learning, and focusing on the students’ center method to improve the studentsEnglish competency so that they are able to compete for educational scholarships in this country and abroad.
