events are major pieces of evidence towards proving that plate tectonics theory is valid (40 marks) The theory of plate tectonics states that the Earth’s lithosphere (top layer of the Earth’s crust) is split up into rigid sections called plates that are moving relative to one another as they move on top of the underlying semi-molten mantle. These plates are either continental‚ The North American Plate‚ or oceanic‚ The Nazca Plate. Tectonic plates are powered by convection currents‚ which is the circular

Tectonics Division of Pakistan Defination: Tectonics zones of Pakistan are the Eurasian Plate‚ Arabian Plate and Indian Plate which is part of Indo-Australian Plate. Eurasian Plate: The Eurasian Plate is a tectonic plate which includes most of the continent of Eurasia (a landmass consisting of the traditional continents of Europe and Asia)‚ with the notable exceptions of the Indian subcontinent‚ the Arabian subcontinent‚ and the area east of the Chersky Range in East Siberia. It also

Lecture How do we explain behavior Behaviour generally refers to actions or reactions (an activity or response of some kind) of an object or organism usually in relation to the environment or surrounding world of stimuli. Behaviour can be conscious or unconscious‚ overt or covert‚ voluntary or involuntary‚ sometimes it can be common‚ unusual‚ acceptable‚ or outside acceptable limits. The acceptability of behavior is evaluated relative to social norms and regulated by various means of social control

1.0 Introduction The Himalayas are the longest and most well known mountain range in the world. It is located just north the Indian sub-continent. It is also home to some of the highest points in the world above sea level‚ Mt. Everest‚ standing at 8‚848 metres above sea level and K2 standing at 8‚611 metres.The main Himalayan range runs from the Indus river valley in the west‚ to the Brahmaputra river valley in the east‚ forming a range with a length of 2‚400 km long‚ which varies in width from

The theory of plate tectonics states that the Earth’s lithosphere is broken up into many different pieces separated by jagged cracks. These are called the tectonic plates. They are in slow‚ constant motion pushed by the convection currents in Earth’s asthenosphere. This theory explains the process of sea floor spreading at mid-ocean ridges‚ and subduction at deep ocean trenches. It was proposed by J. Tuzo Wilson in 1965. He combined the discoveries of Harry Hess and Alfred Wegner to support this

The Indian Himalaya belt is prone to various types of natural disaster due to its inherent nature and climatic conditions. Earthquakes ranging in severity‚ floods or flash flood‚ and glacial lake outbursts are common among other hazards. Monsoon is the time (almost every year) when few water-induced disasters take place in some form or another in various places across this mountain. Cloudbursts‚ that is sudden and violent rainfall‚ followed by flash floods are generally reported in the monsoon period

Volcanic and seismic events are major pieces of evidence towards proving that the plate tectonics theory is valid. The theory of tectonic plates was first posed by Alfred Wenger in 1912. Is the theory of how the earth lithosphere is made up of many separate pieces of the earth’s crust known as tectonic plates. He put forward the idea that all the earth’s continents were once conjoined in one supercontinent called Pangaea‚ and that these continents were moved by convection currents over a period

Explain the use of the word ‘Natural’ in Natural Moral Law (25) In society today‚ we define Nature as something that is not made by humankind but rather is instinctual. St Thomas Aquinas (1225-74) believed our telos can be discovered by using our human reason to reflect on our human nature and work out what we need to do in order to achieve our particular telos. And so Natural Moral Law is defined as the moral Law of God which has been built into us at creation by God. Aquinas’s ideas of Natural

What happens when an oceanic plate converges with a continental plate? The denser oceanic plate slides under the less dense continental plate. 3. A divergent boundary is a boundary between two plates that __________. Move away from each other. 4.Do two colliding continental plates always
