MODUL 1 - RUANG LINGKUP GEOLOGI

1

Pengertian dan cara belajar geologi Geology is the study of the Earth as a whole, its origin, structure, composition, and history (including the development of life), and the nature of the processes which have given rise to its present state.

Whitten, DGA and Brooks, JRV. 1977. The Penguin Dictionary of Geology. Middlesex: Penguin Books. p. 204.

Pertanyaan: Cari definisi lain dari buku-buku geologi berbahasa Inggris di Perpustakaan Pusat.MODUL 1 - RUANG LINGKUP GEOLOGI 2

Pengertian dan cara belajar geologi Mengikuti pendidikan kebumian Lokatama untuk belajar geologi: Perpustakaan termasuk internet Laboratorium (studio) dan museum geologi Lapangan Sebagaimana pembelajaran ilmu alam yang lain, dalam menghadapi bahan atau fenomena geologi perlu dilakukan: Observasi (pengamatan), Analisis, dan SintesisMODUL 1 - RUANG LINGKUP GEOLOGI 3

Perhatikan Belum dikatakan belajar geologi sebelum ke perpustakaan, laboratorium, dan lapangan (survei)! Apakah FTM UPN Veteran Yogyakarta memfasilitasi pembelajaran di 3 (tiga) lokatama termasuk museum- RUANG LINGKUP di atas? tersebut MODUL 1GEOLOGI

Why Study Geology?Because geology is all around us. 1. Geological Resources 2. The Environment Environmental 3. Geological Hazards Geology(Changes posing risks)

4. Engineering 5. Landforms and Surface Processes 6. Historical GeologyGeology forms the basis of our great civilizationsMODUL 1 - RUANG LINGKUP GEOLOGI 14

Why Study Geology?1. Geological Resources The Cradle of Civilization (Fertile Crescent) Development limited by availability, e.g., soil, water, energy Conflicts based on resources, e.g., water, minerals, oilMODUL 1 - RUANG LINGKUP GEOLOGI

Misuse of Resources2. The EnvironmentThese Maps illustrate the Fertile Crescent in 1973 (top) and 2000 (bottom). Permanent marshlands, pictured in green, have shrunk 90 percent in that period.

To prevent slope failure engineers must understand the geology that forms and controls the slopeMODUL 1 - RUANG LINGKUP GEOLOGI 24

Geology in EngineeringThe Leaning Tower Straightens UpIn Pisa the tilted one is back in business after an 11-year effort to keep it from collapsingCommittee member John Burland, an engineer, promoted soil extraction as the best way to save the tower.
