This investigationcompares and contrasts views that children and scientists haveon landforms, particularly on two New Zealand mountains (Mounts Egmont and Cook).Individual interviews were conducted with 37 students during which they observedcolored photographs of'various, well-known New Zealandlandforms and described what they saw. Questioningwas then directed toward eliciting their ideas concerningprocesses behind the appearances of mountains. Sample responses are-presentedrelated to such, questions as: What is a mountmin? Is Mount.Egmont a volcano? When did Mount. Egmont. appear? How do volcanb-es develop?What is a range? How did Mount Cook develop? Responses indicatethat children/adolescents hold views about the two mountains whichare likely to be different from scientifically accepted ideas. For example',approximately 63 percent were not aware that Mount Egmont hes thepotential to erupt again. In addition, the majority of studentshad not attained an appreciation of plate tectonics,even at an elementary level of understanding.

INFORMATION CENTER (E 2 WORKING PAPER 202 . The Science Education Research Unit at the University of Waikato emerged 'from theresearch activity generated by the original Learning in Science Project (1979-1982). The aim of the unit is to facilitate and encourage Science Education Research. One of the most successful innovations ot the Learning in Science Project was the productionof working papersvhereby research findings couldbe shared with practising teachers and-curriculum developers. This present series of papers (the 200 series) continues that tradition for .research undertaken by members of the Unitbut which does not form pait of the Learning in Science Project. We would welcome comment or information related to the topic of this paper. Roger Osborne DIRECTOR, S.E.R.U. MOUNTAINS John C. Happs, Science EducationResearch Unit, University of liaikato, Hamilton, New Zealand. March 1982 Working Paper 202 1 :INTRODUCTION : 4 The Learning in ScienceProject (rRr YBERG, OSBORNE and TASKER,1980) has adopted the view that science teaching,at, all levels might be improved if teachers can be givensome appreciation of students' views ofthe world and the beliefs, expectationsand language that -- learners bring to thenew learning situation. The emphasis throughout the L.I.S.Project hasbeen in the probing of difficulties by means ofsmall-scale, in-depth situdieS that can be relatedto science teaching. The majority of these investigations have beenidentified with the Forms 1 4 science programmes. Many of thd_earlierin-depth stUdiep, . from the L.I:S.Project havetended to concentrate on areas of biology(STEAD, 1980(a); STEAD, 1980(b)) physics(OSBORNE, 980; STEAD and OSBORNE,'1980) and chemistry (HAPPS,1980; scliciuum,ipal). Research into students'concepts and understanding in areas within theearth sciences, has beenundertaken (MOYLE, 1980; HAPPS, 1981(a)) and thispaper contin- ues.to add to our understanding Of teaching and. learnirig problems in thisarea. .This investigationlooks at the,topic.-landforms" and, in particular,focuses attention on two ofNew Zealand's better known mountains, i.e. MountEgmont and Mount Cook. This paper considers these landforms whilst comparingand contrasting 'the views that childrenand adolescents hold, regarding these mountains,with the scientifically acceptable /views. In this way, it is hopedthat a satisfactory 'base-line' can beconstructed so that later teaching can more readilymodify, students' existing knowledge. The topic ,11andformsthas been identified asan important teachingarea, by practising earth scientistsand, secondary teachers, (see HAPPS, 1981(b)) andis included in sections 4(level 4) and 8 (level 5) of the Science: Forms 1 4 Draft Syllabus. The relevant extracts from this syllabusare shown in AppendiX A. WHY STUDY. MOUNTAINS? Ndw Zealand hasexperienced volcanic activity since the mid-Tertiary Iperiod.

This fault, which has beendis- placed a distance of 480km represents a geologically interesting feature withina landmass where two major lithospheric plates interactand form a common boundary. THE EARTH SCIENTISTS' VIEW OF VOLCANISM AND MOUNTAIN BUILDINGIN NEW ZEALAND Prior to any consideration of the ideas and viewsthat children and adolescents may have, concerning Mount Egmont and Mount-Cook, it shouldprove useful and appro- priate to look at theways in which the earth scientist might regard thosesame itwo land forms. ( ") A common mechanism : : It is now generaly acceptedthat almost all volcanic activity, earthquakes and mountain building (collectivelytermed tectonic activity)is located close to plate margins. Where theseplates interact much of the present day geological activity is taking place. New Zealand is situated astride the boundary where two lithospheric platesmeet, The theory. of plate tectonics proposes that the earth's lithosphereis 'broken' intoa number of large 'plates'. Theseldates range in size fromseveral hundred to several thoutand km across, moving at velocities of severalcm per.year. As the plates are in motion, so too..-are the continents. Tlates are able to _change both their size and shape with time, thusnew plates can form as origi- nal ones breakup. or plates may be 'fused' together during'collision. Some platetcanidisappear completely as one plate underridesanother and, at times, the plates have become stationary. (ii) Mount Egmont : This feature is a stratovolcano(significantly larger than Mount St Helens,-in the U.S.A.) which has been built up,fromalternating deposits of lava and ash.to a height of 2,518 metres. Activity probably started at theMount Egmont siteikeout.70,900years before present (B.P.) witha substantial cone having been developed by 2 35,000 years B.P. At about this time a large eruptionled to the collapse : 2.

This .deposit covered an:area of 200 kmato a depth of at least 30 metres and this.H'. kind of 'event'has taken place severaltimes since. Four eruptions have occurred during, the last 500years with the most recent activity, from Mount.. Egmont', taking place in 1755. Future eruptions are highly likely, with the present main crater being the most probable site. Such an eruption would most likely be towardshe west and thereis ample evidence to show that largegmud and debris flows'havc, in thepast, reached Inglewood, Kapuni, Cape EgMont and Opunake. The type of plate margin which isassociated with volcanism in the North. Island of New Zealand,3is destructive, i.e. atanocean trench, two plates approach each other with one'underriding theother.'

Plateaus occur on every continent and take up a third of the Earths land. Plains. A plain is a flat, sweeping landmass that generally does not change much in elevation. Plains occur as lowlands along valleys or on the doorsteps of mountains, as coastal plains. Characteristics and types of plateaus and plains. Plateaus. A plateau is a flat, elevated landform that rises sharply above the surrounding area on at least one side. Plateaus occur on every continent and take up a third of the Earths land. They are one of the four major landforms, along with mountains, plains, and hills. There are two kinds of plateaus: dissected plateaus and volcanic plateaus. A dissected plateau forms as a result of upward movement in the Earths crust. The uplift is caused by the slow collision of tectonic plates. The Colorado Plateau, in the western United States, has been rising about .03 centimeter (.01 inch) a year for more than 10 million years. A volcanic plateau is formed by numerous small volcanic eruptions that slowly build up over time, forming a plateau from the resulting lava flows. The North Island Volcanic Plateau covers most of the central part of the North Island of New Zealand. This volcanic plateau still has three active volcanoes: Mount Tongariro, Mount Ngauruhoe, and Mount Ruapehu. Erosion can influence the shape of a plateau. Soft rock often erodes away on the top of a plateau.

    www.nature.com/scientificreports OPEN Rifting of the oceanic Azores Plateau with episodic volcanic activity B. Storch1*, K. M. Haase1, R. H. W. Romer1, C. Beier1,2 & A. A. P. Koppers3 Extension of the Azores Plateau along the Terceira Rift exposes a lava sequence on the steep northern fank of the Hirondelle Basin. Unlike typical tholeiitic basalts of oceanic plateaus, the 1.2 km vertical submarine stratigraphic profle reveals two successive compositionally distinct basanitic to alkali basaltic eruptive units. The lower unit is volumetrically more extensive with ~ 1060 m of the crustal profle forming between ~ 2.02 and ~ 1.66 Ma, followed by a second unit erupting the uppermost ~ 30 m of lavas in ~ 100 kyrs. The age of ~ 1.56 Ma of the youngest in-situ sample at the top of the profle implies that the 35 km-wide Hirondelle Basin opened after this time along normal faults. This rifting phase was followed by alkaline volcanism at D. João de Castro seamount in the basin center indicating episodic volcanic activity along the Terceira Rift. The mantle source compositions of the two lava units change towards less radiogenic Nd, Hf, and Pb isotope ratios. A change to less SiO2-undersaturated magmas may indicate increasing degrees of partial melting beneath D. João de Castro seamount, possibly caused by lithospheric thinning within the past 1.5 million years. Our results suggest that rifting of oceanic lithosphere alternates between magmatically and tectonically dominated phases. Oceanic plateaus with a crustal thickness to 30 km cover large areas in the oceans and these bathymetric swells afect oceanic currents and marine life 1,2.

  • Volcanic Features of New Mexico Analogous to Volcanic Features on Mars
    Volcanic features of New Mexico analogous to volcanic features on Mars Larry S. Crumpler. Jayne C. Aubele New Mexico Museum of Naniral History and Science. Albuquerque and James R. Zimbelnian Center for Earlh and Plunctury Studies, national Air and Space Museum, Smithsonian Insiiiuiion. Wasliington 4.1 Introduction The arid climate, extensional rift setting, range in type and age of volcanic eruptions, and generally widespread and geologically youthful volcanism in New Mexico contribute to an environment rich in geologic processes and landforms analogous to many of those on Mars. Young (<5 Ma) volcanoes and associated volcanic rocks are more widely distributed throughout the state than in many other volcanic localities on the North American continent. All of the principal volcanic landforms occur including long lava flows, viscous domes, calderas, composite volcanoes, monogenetic scoria cones, small shield volcanoes, and numerous hydromagmatic vents. The morphol- ogies, volcanic emplacement processes, and dissected structures, and the arid environment, result in many volcanic landforms analogous to those on Mars. These features provide some clues to the details of geologic processes respon- sible for their Martian counterparts that are uncommon in areas where volcanism is less abundant and where the environments are less arid. The largest young caldera (Valles Caldera), largest young lava flows (McCartys and Carrizozo), abundance of Quaternary volcanic fields, volatile-rich magmatism, including non-juvenile (maars) and juvenile types (Shiprock-Narbona Pass), spring deposits, and one of the great modern rift valleys on Earth (Rio Grande rift) occur in an arid setting where annual precipitation is between 8 and 15 inches (20-40 cm) per year.

Cesta B.S. (Geology), The Richard Stockton College of New Jersey, May 2013 June, 2015 Cincinnati, OH Advisory Committee: Dr. Dylan J. Ward, Ph.D. (Chair) Dr. Craig Dietsch, Ph.D. (Member) Dr. Lewis A. Owen, Ph.D. (Member) Keywords: Alluvial fans, debris flows, cosmogenic nuclides, Atacama Desert, central Andes Timing of alluvial fan development along the Chajnantor Plateau, Atacama Desert, northern Chile: Insights from cosmogenic 36Cl Jason M. Cesta Abstract An extensive alluvial apron of coalescing gravel fans blankets the western flank of the Chajnantor Plateau in the Atacama Desert of northern Chile. Remnant alluvial surfaces, terraces, and intermittent debris flow deposits preserved in this bajada indicate multiple intervals of aggradation, incision and terrace abandonment, and deposition. The high preservation potential and sensitivity to climate shifts of the region provides a unique opportunity to elucidate the sedimentary response to climate variations at an extreme of Earth’s climate. Cosmogenic 36Cl exposure dating, aided by mapping, is used to establish a detailed chronology of the depositional history of the Chajnantor alluvial apron. Alluvial surfaces and gravel deposits yield cosmogenic exposure ages ranging from 20.7 ± 1.4 ka to 419.2 ± 39.6 ka. Debris flow boulders confined to modern and ancient channels yield cosmogenic exposure ages ranging from 9.3 ± 1.1 ka to 202.5 ± 19.6 ka.

Extensive volcanic activity in the Georgian part of the Caucasian mobile belt took place during the Late Miocene−Holocene. Five volcanic regions have been identifi ed in Georgia; each of them reveals in a greater or lesser degree similarity of tectonic and magmatic processes. Volcanic products are represented by basaltic, doleritic, andesitic basaltic, andesitic dacitic, rhyolitic lavas and their pyroclastics with andesites and dacites prevailing. Using petrochemical and geochemical data the volcanics can be divided into two main rock groups: calc-alkaline and subalkaline series. Th e marker petrogeochemical series is presented by the medium- to high-K calc-alkaline volcanics. Relative to the heavy elements (HFSE) Y, Nb they are enriched in some large ion lithophile elements (LILE) Rb, Sr, Ba and light rare earth elements (REE) La, Ce.
