Q1. Sketch and describe one environment in which mountains typically form, including its plate tectonic setting, changes affecting the crust, structural and metamorphic features, and the life cycle of the mountain range. Create a concept sketch of the region, including appropriate thickness and location of the lithosphere and asthenosphere. Label, using arrows, the direction of plate movement. As the mountains form, what happens to the thickness and elevation of the crust? Explain why this happens. b. d. Within that setting, in what specific locations does metamorphism occur (indicate this on your diagram by circling these locations)? Name two types of metamorphic rock that might be found within the mountains: Describe the parent rock, the type of metamorphic rock it would become, and where within the mountain belt each of the two types of metamorphic rocks would be found. Name and describe 2 types of deformation features that might be observed in this setting (indicate these on your diagram). Explain why these features form where they do-in your answer consider: direction and velocity of plate motion, temperature, pressure, and rock type. What will happen to the mountains over the next 100 million years, and what will they look like then? What will happen and what will the mountains look like after 1 billion years? What type of bedrock will be exposed at the Earth's surface at the mountains' location after 1 billion years? Where will the material that made up the original mountain range eventually end up, and why? e. g. h. i.Explanation / Answer
This is also known as fold montain which is formed due to collision of two plates towards each other. changes occur in the form of upliftment and upfolding of the crust which results into mountain building.
Structural fearures must be like folding ,faulting, fractures, as well as cleavages got developed on the rock body due to continous pressure exercting on that body.
where as metamorphic features which forms due to pressure , temperature and chemical reaction acting on the rock body will depend on the rock type, weathering factor as well as on pressure temperature condition.
Its life cycle depend on stabilizing or destabilizing links, As the mountains grow taller, erosion increases, and start reducing the growth rate and finally a peneplain feature occur.
As the mountain form, its elevation of crust depends upon the thickness and density of the crust and this whole phenomena is ralated to isostasy.
2 metamorphic rocks formed within the mountain are (1) QUARTZITE AND (2) MARBLE, Quartzite forms from sandstone and Marble forms from Limestone and they are non- foliated metamorphic rocks and are found deep buried in an orogenig belt.
the mountain which is at its peak at present after 100 millions of years it will be a plain area or a small elevation would be left as there is one saying also, the one which goes high ultimately comes down too.
