What is end moraine in geology?
GeologyA terminal, or end, moraine consists of a ridgelike accumulation of glacial debris pushed forward by the leading glacial snout and dumped at the outermost edge of any given ice advance. It curves convexly down the valley and may extend up the sides as lateral moraines. How does end moraine form? How do end moraines
What are biophysical factors?
GeologyBiophysical factors generally refer to the non-living environment (lithosphere, hydrosphere, atmosphere), while ecological factors generally refers to the living components of the environments (biosphere – special environments, animals, plants, etc). What are biophysical examples? The biophysical environment can vary in scale from microscopic to global in extent. It can also be subdivided according to its
Why do people live and farm on volcanoes?
GeologyFor starters, many people depend on volcanoes for their survival. The geothermal energy of a volcano can power technological systems for nearby communities. Soil near active volcanoes is often rich in mineral deposits and provides excellent farming opportunities. Why do people farm by volcanoes? Farming.

Was the Montserrat Volcano predicted?
GeologyThe observatory’s staff failed to predict the explosion of magma on 17 September 1996, which caused a 40,000-feet high plume of ash, and deposited 600,000 tonnes of ash on the south of the island. Their prediction of a similar eruption in December the same year turned out to be a false alarm.1 апр. 1998 What

What is tensional stress?
GeologyTensional stress is the stress that tends to pull something apart. It is the stress component perpendicular to a given surface, such as a fault plane, that results from forces applied perpendicular to the surface or from remote forces transmitted through the surrounding rock. What is caused by tensional stress? Compressional stresses cause a rock
